背景技术Background technique
饮水问题是民众非常关注的问题，水中有很多不利于健康的物质已是不争的事实，这也是老百姓健康饮水已是得到加强的主要原因，也是净水设备市场火爆的根源。The problem of drinking water is a matter of great concern to the public. It is an indisputable fact that there are many substances that are not conducive to health in the water. This is also the main reason why people's healthy drinking water has been strengthened, and it is also the root of the hot water purification equipment market.
现有净水系统的核心部件是膜滤芯，与其连接的管路包括原水管路、纯水管路、废水管路以及回流管路，该回流管路将废水管路和原水管路连通，以使得膜滤芯过滤后产生的废水有一部分能够重新回流至膜滤芯内进行过滤，这样就提高了整个净水系统的产水率，也提高了水的利用率。The core component of the existing water purification system is the membrane filter element, and the pipelines connected to it include raw water pipelines, pure water pipelines, waste water pipelines and return pipelines. The return pipeline connects the waste water pipelines with the raw water pipelines to Part of the wastewater generated after filtration by the membrane filter element can flow back into the membrane filter element for filtration, thus improving the water production rate of the entire water purification system and improving the water utilization rate.
然而，现有的膜滤芯的内部水路中水流速度较缓，这样就容易沉积污垢和杂质，进而导致膜滤芯的内部水路被堵塞，进而导致整个净水系统产水率低，造成了水的浪费。However, the water flow rate in the internal water channel of the existing membrane filter element is relatively slow, so it is easy to deposit dirt and impurities, which leads to the blockage of the internal water channel of the membrane filter element, resulting in low water production rate of the entire water purification system, resulting in waste of water .

需要说明的是，多个反渗透膜片组123沿着中心管121的周向一同卷至多个排废管122的外侧时，由每一反渗透膜片组123对折形成的进水通道和由两个相邻反渗透膜片组123共同构成的产水通道均呈螺旋状设置，如此设置，一方面保证了膜元件12的进水通道和产水通道的长度，从而使得该膜元件12的进水通道能够容纳更多的原水，并且较长的进水通道和产水通道能够保证整个膜元件12的过滤效率；另一方面，每一进水通道位于最外侧的一端均呈敞口设置，以形成进水通道的原水入口，壳体11与膜元件12之间的原水可以通过进水通道的原水入口进入进水通道内。由于设置于膜元件12侧面的原水入口要大于设置于膜元件12两端的原水入口，这样就使得该膜元件12的进水通道的进水速度要大于传统膜元件12的进水速度，并且在进水通道内水流速度快的情况下，污垢和杂质是不易沉积于进水通道内，这样就能够避免反渗透膜片组123被堵塞，有利于延长膜滤芯10的使用寿命。It should be noted that when a plurality of reverse osmosis membrane groups 123 are rolled together to the outside of the plurality of waste discharge pipes 122 along the circumferential direction of the central pipe 121, the water inlet channel formed by each reverse osmosis membrane group 123 folded in half and formed by The water production channels jointly formed by two adjacent reverse osmosis membrane groups 123 are arranged in a spiral shape, so that, on the one hand, the length of the water inlet channel and the water production channel of the membrane element 12 is guaranteed, so that the membrane element 12 The water inlet channel can accommodate more raw water, and the longer water inlet channel and water production channel can ensure the filtration efficiency of the entire membrane element 12; on the other hand, the outermost end of each water inlet channel is open. , to form the raw water inlet of the water inlet channel, the raw water between the casing 11 and the membrane element 12 can enter the water inlet channel through the raw water inlet of the water inlet channel. Since the raw water inlet arranged on the side of the membrane element 12 is larger than the raw water inlet arranged at both ends of the membrane element 12, the water inlet speed of the water inlet channel of the membrane element 12 is greater than the water inlet speed of the traditional membrane element 12, and in When the water flow in the water inlet channel is fast, dirt and impurities are not easily deposited in the water inlet channel, so that the reverse osmosis membrane set 123 can be prevented from being blocked, which is beneficial to prolong the service life of the membrane filter element 10 .

The amount of wastewater discharged from the system 100 increases the water production rate of the water purification system 100 . And because the membrane element 12 in the membrane filter element 10 is side water inlet, the water inlet velocity of the membrane element 12 has been guaranteed like this, that is to say, the water flow velocity of the water inlet channel of the membrane element 12 has been ensured, and the water inlet channel has a faster water flow velocity. In the case of low temperature, dirt and impurities are not easy to deposit in the water inlet channel, which ensures that the membrane element 12 will not be blocked, thereby ensuring that the water purification system 100 can fully filter the raw water, which is conducive to improving the water purification system 100. water production rate.
在本实用新型的一实施例中，请参照图3，该反渗透膜片组123包括反渗透膜片123a、纯水导流网123b以及进水导流网123c；该反渗透膜片123a的正面在反渗透膜片123a的一端从中心管121和一排废管122之间穿过后对折，形成上述进水通道，相邻两反渗透膜片123a的反面之间形成产水通道。进水导流网123c安装于进水通道内，原水在进水导流网123c的导流作用下在进水通道内流动，并在渗透压力的作用下从进水通道向产水通道渗透，即进水通道内的原水穿过反渗透膜片123a进入产水通道形成纯水。纯水导流网123b安装于产水通道内，产水通道内的纯水在纯水导流网123b的导流作用下向中心管121流动。In an embodiment of the present utility model, please refer to FIG. 3 , the reverse osmosis membrane group 123 includes a reverse osmosis membrane 123a, a pure water guide net 123b and an inlet water guide net 123c; the reverse osmosis membrane 123a The front side is folded in half after one end of the reverse osmosis membrane 123a passes between the central pipe 121 and a row of waste pipes 122 to form the above-mentioned water inlet channel, and a water production channel is formed between the opposite sides of two adjacent reverse osmosis membranes 123a. The water inlet diversion net 123c is installed in the water inlet channel, and the raw water flows in the water inlet channel under the diversion action of the water inlet diversion net 123c, and permeates from the water inlet channel to the water production channel under the action of osmotic pressure, That is, the raw water in the water inlet channel passes through the reverse osmosis membrane 123a and enters the product water channel to form pure water.

需要说明的是，每一进水通道远离排废管122的一侧呈敞口设置，也即每一反渗透膜片123a垂直排废管122的侧边均通过防水胶密封粘接；每一产水通道邻近中心管121的一侧呈敞口设置，也即相邻两反渗透膜片123a除邻近中心管121的侧边未通过防水胶密封粘接外，其他侧边均通过防水胶密封粘接，这样使得进水通道和产水通道完全隔绝，进而避免了进水通道内的原水进入产水通道内，而导致产水通道内的纯水被进水通道内的原水污染。It should be noted that the side of each water inlet channel away from the waste discharge pipe 122 is open, that is, the sides of each reverse osmosis membrane 123a vertical to the waste discharge pipe 122 are sealed and bonded by waterproof glue; One side of the water production channel adjacent to the central tube 121 is open, that is, the two adjacent reverse osmosis membranes 123a are sealed with waterproof adhesive except for the side adjacent to the central tube 121 which is not sealed with waterproof adhesive. In this way, the water inlet channel and the water production channel are completely isolated, thereby preventing the raw water in the water inlet channel from entering the water production channel, and causing the pure water in the water production channel to be polluted by the raw water in the water inlet channel.
另外，对折后的反渗透膜片123a的正面在进水导流网123c的作用下呈相互间隔设置，相邻两反渗透模片的反面在纯水导流网123b的作用下呈相互间隔设置，这样就有利于保证反渗透膜片123a的过滤面积，从而有利于提高膜元件12的过滤效率。In addition, the fronts of the folded reverse osmosis membranes 123a are arranged at intervals from each other under the action of the water inlet guide net 123c, and the opposite sides of two adjacent reverse osmosis membranes are arranged at intervals from each other under the action of the pure water guide net 123b , which is beneficial to ensure the filtration area of the reverse osmosis membrane 123a, thereby improving the filtration efficiency of the membrane element 12.
为了保证每一个产水通道内的纯水都能够及时的收集到中心管121中，请参照图4，该中心管121上设有多个纯水入水孔121a，并且多个纯水入水孔121a沿着中心管121的长度方向间隔排布，由此，使得产水通道邻近中心管121的每个位置都能够通过纯水入水孔121a快速流入中心管121中，进而有利于提高膜滤芯10的产水速度。In order to ensure that the pure water in each water production channel can be collected in the central tube 121 in time, please refer to Figure 4, the central tube 121 is provided with a plurality of pure water inlet holes 121a, and a plurality of pure water inlet holes 121a Arranged at intervals along the length direction of the central tube 121, thus, each position of the water production channel adjacent to the central tube 121 can quickly flow into the central tube 121 through the pure water inlet hole 121a, which is conducive to improving the performance of the membrane filter element 10. Water production rate.
为了保证每一排废管122所在的进水通道内的废水能够及时收集至排废管122中，请参照图5，每一排废管122上设置有多个废水入水孔122a，且多个废水入水孔122a沿着该排废管122的长度方向均匀排布，如此，使得废水通道的邻近排废管122的每个位置都能够通过废水入水孔122a快速流入排废管122中，有利于膜滤芯10内废水的排出，避免了废水滞留于进水通道内的时间过长而导致废水中的杂质在反渗透膜片组123上结垢，进而影响反渗透膜片组123的过滤效果。In order to ensure that the waste water in the water inlet channel where each waste pipe 122 is located can be collected into the waste pipe 122 in time, please refer to FIG. The waste water inlet holes 122a are evenly arranged along the length direction of the waste discharge pipe 122, so that each position of the waste water channel adjacent to the waste discharge pipe 122 can quickly flow into the waste discharge pipe 122 through the waste water inlet holes 122a, which is beneficial to The discharge of the wastewater in the membrane filter element 10 avoids the impurities in the wastewater from fouling on the reverse osmosis membrane set 123 caused by the waste water staying in the water inlet channel for too long, thereby affecting the filtering effect of the reverse osmosis membrane set 123 .
在本实用新型的一实施例中，请参照图1，该废水回流阀20的开度为可调节设置，为了方便控制废水调节阀的开度，该净水系统100还设置有第一TDS检测装置30，该第一TDS检测装置30安装于废水回流阀20上或者第一TDS检测装置30安装于废水回流阀20的进水端或出水端。第一TDS检测装置30用于检测通过废水回流阀20的废水的TDS值，并将检测结果发送至控制器，控制器根据第一TDS检测装置30发送的检测结果调节废水回流阀20的开度。In an embodiment of the present utility model, please refer to FIG. 1 , the opening of the wastewater return valve 20 is adjustable. In order to facilitate the control of the opening of the wastewater regulating valve, the water purification system 100 is also provided with a first TDS detection A device 30 , the first TDS detection device 30 is installed on the wastewater return valve 20 or the first TDS detection device 30 is installed at the water inlet or outlet of the waste water return valve 20 . The first TDS detection device 30 is used to detect the TDS value of the wastewater passing through the waste water return valve 20, and send the detection result to the controller, and the controller adjusts the opening of the waste water return valve 20 according to the detection result sent by the first TDS detection device 30 .
具体的，在净水系统100工作时，若第一TDS检测装置30检测到的废水的TDS值大于第一预设TDS值，控制器控制废水回流阀20的开度减小。由于通过废水回流阀20的废水的TDS值偏高，也就表明从膜滤芯10的废水口c排出的废水的水质较差，将废水回流阀20的开度减小，这样就可以减少水质较差的废水回流至膜滤芯10内，进而能够有效地避免膜滤芯10内的膜元件12被废水中杂质所封堵。若第一TDS检测装置30检测到的废水的TDS值小于或等于第一预设TDS值，控制器则控制废水回流阀20的开度增大或保持不变。由于通过废水回流阀20的废水的水质较好，将废水回流阀20的开度增大或保持不变，能够保证有足够多的废水回流至膜滤芯10内，从而减少了膜滤芯10的废水排出量，进而使得更多的废水得到重新过滤，提高了水的利用率。Specifically, when the water purification system 100 is working, if the TDS value of the wastewater detected by the first TDS detection device 30 is greater than the first preset TDS value, the controller controls the opening of the wastewater return valve 20 to decrease. Because the TDS value of the waste water passing through the waste water return valve 20 is relatively high, it also shows that the water quality of the waste water discharged from the waste water outlet c of the membrane filter element 10 is relatively poor, so the opening of the waste water return valve 20 is reduced, so that the poor water quality can be reduced. Poor waste water flows back into the membrane filter element 10, thereby effectively preventing the membrane elements 12 in the membrane filter element 10 from being blocked by impurities in the waste water. If the TDS value of the wastewater detected by the first TDS detection device 30 is less than or equal to the first preset TDS value, the controller controls the opening of the wastewater return valve 20 to increase or remain unchanged. Because the water quality of the waste water passing through the waste water backflow valve 20 is better, increasing or keeping the opening of the waste water backflow valve 20 unchanged can ensure that enough waste water flows back into the membrane filter element 10, thereby reducing the waste water of the membrane filter element 10 discharge, which in turn enables more wastewater to be re-filtered, improving water utilization.
在本实用新型的一实施例中，请参照图1，该净水系统100还包括与控制器电性连接的废水电磁阀40和第二TDS检测装置50，该废水电磁阀40和第二TDS检测装置50均安装于废水管上，第二TDS检测装置50用于检测通过废水管并排至外界的废水的TDS值，并将检测结果发送至控制器；控制器根据第二TDS检测装置50发送的检测结果调节废水电磁阀40的开度。In an embodiment of the present utility model, please refer to FIG. 1, the water purification system 100 also includes a waste water solenoid valve 40 and a second TDS detection device 50 electrically connected to the controller, the waste water solenoid valve 40 and the second TDS The detection devices 50 are all installed on the waste water pipes, and the second TDS detection device 50 is used to detect the TDS value of the waste water that passes through the waste water pipes and is discharged to the outside, and sends the detection results to the controller; The detection result adjusts the opening degree of the waste water solenoid valve 40.
具体的，在净水系统100工作时，若第二TDS检测装置50检测到通过废水管排至外界的废水的TDS值小于或等于第二预设TDS值时，控制器控制废水电磁阀40的开度减小或保持不变。由于从废水管排至外界的废水的水质较好，将废水电磁阀40的开度减小，就可以使得更多的废水回流至膜滤芯10内并重新过滤，这样就提高了水的利用率。若第二TDS检测装置50检测到通过废水管排至外界的废水的TDS值大于第二预设TDS值，控制器控制废水电磁阀40的开度增大。由于从废水管排至外界的废水水质较差，也就是说从废水管排至外界的废水中含有的杂质过多，将废水电磁阀40的开度增大，这样就使得从膜滤芯10排出的废水基本上通过废水管排至外界，进而就避免了膜滤芯10内的膜元件12被废水中的杂质所封堵。并且，在废水电磁阀40的开度增大时，膜滤芯10的废水排出的速度也会得到提高，废水流速的增大使得吸附于膜滤芯10的膜元件12的杂质容易被冲洗出来，这样有利于延长膜滤芯10的使用寿命。Specifically, when the water purification system 100 is working, if the second TDS detection device 50 detects that the TDS value of the waste water discharged to the outside through the waste pipe is less than or equal to the second preset TDS value, the controller controls the waste water solenoid valve 40 to The opening decreases or remains the same. Since the water quality of the waste water discharged from the waste water pipe to the outside is better, reducing the opening of the waste water solenoid valve 40 can make more waste water flow back into the membrane filter element 10 and re-filter, thus improving the utilization rate of water . If the second TDS detection device 50 detects that the TDS value of the waste water discharged to the outside through the waste pipe is greater than the second preset TDS value, the controller controls the opening of the waste water solenoid valve 40 to increase. Due to the poor water quality of the waste water discharged from the waste pipe to the outside world, that is to say, the waste water discharged from the waste pipe to the outside contains too many impurities. The waste water is basically discharged to the outside through the waste water pipe, thereby preventing the membrane element 12 in the membrane filter element 10 from being blocked by impurities in the waste water. And, when the opening degree of waste water solenoid valve 40 increases, the speed of the waste water discharge of membrane filter element 10 also can be improved, and the increase of waste water flow rate makes the impurity that is adsorbed on the membrane element 12 of membrane filter element 10 be washed out easily, like this It is beneficial to prolong the service life of the membrane filter element 10 .
进一步地，上述废水电磁阀40的规格小于或等于800cc/min。采用规格小于800cc/min的废水电磁阀40，能够减少净水系统100的废水排出量，以确保废水电磁阀40即使处于全开状态时，净水系统100的纯水排出量与废水排出量的比例保持为3比1或者大于3比1，这样就大大地提高了净水系统100的产水率，减少了废水的产生。Further, the specification of the wastewater solenoid valve 40 is less than or equal to 800cc/min. The wastewater solenoid valve 40 with a specification of less than 800cc/min can reduce the discharge of wastewater from the water purification system 100, so as to ensure that even when the wastewater solenoid valve 40 is in a fully open state, the pure water discharge of the water purification system 100 is equal to the wastewater discharge. The ratio is kept at 3 to 1 or greater than 3 to 1, which greatly improves the water production rate of the water purification system 100 and reduces the generation of waste water.
在本实用新型的一实施例中，请参照图1，该净水系统100还包括一第一单向阀60，该第一单向阀60串接至废水回流阀20的进水端或出水端。可以理解的是，第一单向阀60只能单向导通，这样就使得原水管内的原水无法通过第一单向阀60和废水回流阀20所在的管路直接流入废水管中，进而确保了废水管中的废水能够顺利的从废水回流阀20的进水端向废水回流阀20的出水端流动，并通过原水管流入膜滤芯10内重新进行过滤，这样有利于提高净水系统100的产水率。In an embodiment of the present utility model, please refer to FIG. 1, the water purification system 100 also includes a first one-way valve 60, which is connected in series to the water inlet or outlet of the waste water return valve 20 end. It can be understood that the first one-way valve 60 can only conduct in one direction, so that the raw water in the raw water pipe cannot directly flow into the waste water pipe through the pipeline where the first one-way valve 60 and the waste water return valve 20 are located, thereby ensuring The waste water in the waste water pipe can smoothly flow from the water inlet end of the waste water return valve 20 to the water outlet end of the waste water return valve 20, and flow into the membrane filter element 10 through the raw water pipe for re-filtering, which is conducive to improving the production capacity of the water purification system 100. water rate.
在本实用新型的一实施例中，请参照图1，该净水系统100还包括增压泵65，该增压泵65安装于位于原水口a与废水回流阀20的进水端之间的原水管上，该增压泵65用于给原水管内的原水加压，如此设置，一方面保证了从原水管流入膜滤芯10捏的水压足够高，进而有利于提高膜滤芯10制取纯水的速度；另一方面，由于废水回流阀20的进水端位于增压泵65的进水侧，如此设置还便于废水回流至膜滤芯10内。In an embodiment of the present utility model, please refer to FIG. 1 , the water purification system 100 also includes a booster pump 65, which is installed in the water inlet between the raw water port a and the waste water return valve 20. On the raw water pipe, the booster pump 65 is used to pressurize the raw water in the raw water pipe. This arrangement ensures that the water pressure flowing into the membrane filter element 10 from the raw water pipe is high enough, which is conducive to improving the production of pure water by the membrane filter element 10. On the other hand, since the water inlet end of the waste water return valve 20 is located at the water inlet side of the booster pump 65, such setting also facilitates the return of waste water to the membrane filter element 10.
优选地，上述增压泵65为变频增压泵65，由于变频增压泵65的频率是可调，用户可以根据需求调整变频增压泵65的工作频率。当增压泵65的频率较高时，同一时间段内通过增压泵65的原水水量会较多，这样就使得进入膜滤芯10内的原水水量增多，进而有利于提高膜滤芯10制取纯水的速度；当增压泵65的频率较低时，同一时间段内通过增压泵65的原水水量会较少，这样就使得进入膜滤芯10内的原水水量减少，从而减缓了膜滤芯10的过滤速度，进而使得膜滤芯10内的原水能够得到充分的过滤，有利于提高原水的使用率。Preferably, the above-mentioned booster pump 65 is a variable frequency booster pump 65. Since the frequency of the variable frequency booster pump 65 is adjustable, the user can adjust the operating frequency of the variable frequency booster pump 65 according to requirements. When the frequency of the booster pump 65 is high, the amount of raw water passing through the booster pump 65 will be more in the same time period, so that the amount of raw water entering the membrane filter element 10 will increase, which will help improve the purity of the membrane filter element 10. The speed of water; when the frequency of the booster pump 65 is low, the amount of raw water passing through the booster pump 65 in the same period of time will be less, so that the amount of raw water entering the membrane filter element 10 will decrease, thereby slowing down the membrane filter element 10. The filtration speed is high, and the raw water in the membrane filter element 10 can be fully filtered, which is beneficial to improve the utilization rate of raw water.
进一步地，请参照图1，该净水系统100还包括安装于增压泵65进水侧的进水阀70，废水回流阀20的进水端连接至位于增压泵65与进水阀70之间的原水管上；控制器还与进水阀70电性连接，并且在净水系统工作时控制进水阀70开启，在净水系统停止工作时控制进水阀70关闭。该进水阀70的设置，确保了净水系统停止工作时，位于增压泵65进水侧的原水管内存留有原水，这样就避免了增压泵65在下次启动时出现空转的情况出现，进而有效的保护了增压泵65。Further, please refer to FIG. 1 , the water purification system 100 also includes a water inlet valve 70 installed on the water inlet side of the booster pump 65 , and the water inlet end of the waste water return valve 20 is connected to the water inlet valve 70 located between the booster pump 65 and the water inlet valve 70 . The controller is also electrically connected to the water inlet valve 70, and controls the water inlet valve 70 to open when the water purification system is working, and controls the water inlet valve 70 to close when the water purification system stops working. The setting of the water inlet valve 70 ensures that when the water purification system stops working, raw water remains in the raw water pipe on the water inlet side of the booster pump 65, thus preventing the booster pump 65 from idling when it is started next time. , thereby effectively protecting the booster pump 65.
进一步地，请参照图1，该净水系统100还包括安装于纯水管上的压力检测装置75，控制器与压力检测装置75电性连接，并且该控制器用于在压力检测开关检测到的压力值小于预设压力值时，控制增压泵65和废水回流阀20开启，也即控制净水系统100制取纯水；该控制器在压力检测开关检测到压力值大于或等于预设压力值时，控制增压泵65和废水回流阀20关闭。Further, please refer to FIG. 1, the water purification system 100 also includes a pressure detection device 75 installed on the pure water pipe, the controller is electrically connected to the pressure detection device 75, and the controller is used to detect the pressure detected by the pressure detection switch. When the pressure value is less than the preset pressure value, control the booster pump 65 and the waste water return valve 20 to open, that is, control the water purification system 100 to produce pure water; the controller detects that the pressure value is greater than or equal to the preset pressure value, the control booster pump 65 and the waste water return valve 20 are closed.
具体的，该压力检测装置75为压力开关，当纯水管的出水端打开时，由于纯水向出水端流动，这样就使得压力开关处的压力降低，即表明用户需要用水，此时控制器控制增压泵65和废水回流阀20打开，也即启动净水系统100制取纯水。当纯水管的出水端关闭时，此时膜滤芯10内的纯水会持续向纯水管的出水端流，直至充满整个纯水管，这样就使得纯水管内的压力增大，当压力开关检测到纯水管内的压力增大时，控制器控制废水回流阀20和增压泵65关闭。Specifically, the pressure detection device 75 is a pressure switch. When the water outlet of the pure water pipe is opened, the pure water flows to the water outlet, which reduces the pressure at the pressure switch, indicating that the user needs water. At this time, the controller Control the booster pump 65 and the waste water return valve 20 to open, that is, start the water purification system 100 to produce pure water. When the water outlet end of the pure water pipe is closed, the pure water in the membrane filter element 10 will continue to flow to the water outlet end of the pure water pipe until the entire pure water pipe is filled, so that the pressure in the pure water pipe increases. When the switch detects that the pressure in the pure water pipe increases, the controller controls the waste water return valve 20 and the booster pump 65 to close.

Install the pre-filter 80 in front of the raw water pipe, so that the large particles of impurities in the raw water can be effectively filtered out, thereby avoiding the problem that the particles of impurities in the raw water are attached to the membrane element 12 of the membrane filter element 10 and cause the membrane element 12 to be blocked. .
优选地，上述前置滤芯80为P复合滤芯，该P复合滤芯包括无纺布、碳纤维和PP棉三层复合形成，即P复合滤芯集合了碳纤维滤芯和PP棉滤芯的功能，也即用一个滤芯可以代替两个滤芯，这样就减少了前置滤芯80的数量，进而使得整个净水系统100所需要的安装空间更小。Preferably, the above-mentioned pre-filter element 80 is a P composite filter element, which is composed of three layers of non-woven fabric, carbon fiber and PP cotton, that is, the P composite filter element combines the functions of a carbon fiber filter element and a PP cotton filter element, that is, a The filter element can replace two filter elements, thus reducing the number of pre-filter elements 80 , thereby making the installation space required by the entire water purification system 100 smaller.
