First, the process
Tap water → original water tank → original water pump → quartz sand filter → activated carbon filter → precision
Filter → high pressure pump → pure water host → pure water tank → pure water pump → water point
Second, the system introduction:
(1) Pretreatment system
The pretreatment function is to perform primary treatment on raw water to remove suspended solids and colloids in water to ensure stable operation of reverse osmosis equipment. The requirements for reverse osmosis pretreatment are as follows:
Prevent the surface contamination of the membrane, that is, prevent the suspended matter, microorganisms, colloids and the like from adhering to the water flow passage of the membrane element on the surface of the membrane.
Prevent fouling of the membrane surface. In the operation of the reverse osmosis device, due to the concentration of the raw water, some insoluble salts such as CaCO3, CaSO4, SrO4, CaF2, etc. are deposited on the surface of the membrane, so that the formation of these insoluble salts is prevented.
Ensure that the membrane is protected from mechanical and chemical damage so that the membrane has good performance and a long enough life.
Therefore, the pretreatment equipment adopts a process of raw water→raw water pump→multi-media filtration→activated carbon filtration→precision filtration.
Original water tank
Overcoming the instability of the water supply of the pipe network, ensuring the stable and continuous water supply of the whole system; at the same time, it also provides a guarantee for the long-term performance of each equipment.
2. Original water pump
The raw water pump provides the necessary operating pressure for the pretreatment system.
3 multi-media filter
Its function is to remove suspended solids and colloids in water and reduce the turbidity of raw water. The filtering equipment adopts multi-media filtration, and the filter medium is filled with different density and different particle size filter media. The density of the filter medium is from small to large and the particle size is arranged from large to small, and the intercepting capacity is gradually increased along the process, thereby realizing the whole layer. The best match between the filter interception capacity and the difficulty of removing residual impurities. Multi-media filters have the following advantages over ordinary single-layer filters:
Large interception capacity
Long filter period
Good effluent quality
Head loss growth is slow
The multi-media filter device is composed of a steel filter tank, a water distribution device, a gas distribution device, an automatic control valve, filter media of various particle sizes, related accessories, and pipelines.
4. Activated carbon filter
Activated carbon has a large void ratio and specific surface area, which makes it have a strong adsorption capacity, which can remove free chlorine and organic matter in water to protect the subsequent desalination facilities. In order to prevent the suspended matter from blocking the void structure of the activated carbon, the activated carbon is filtered and added after the multi-media filtration. Since activated carbon filtration has the advantages of simple equipment, low investment, convenient operation and easy control, and so on, it is widely used in water treatment and purification systems.
The need for free chlorine and organic removal:
Free chlorine can oxidize and destroy reverse osmosis membrane. Reverse osmosis generally requires residual chlorine of <0.1ppm; organic matter is not only a feed for microorganisms, but when it is concentrated to a certain extent, organic membrane material can be dissolved to deteriorate membrane performance.
There are many kinds of organic substances in water, and different organic substances have different hazards to reverse osmosis membranes. Therefore, in the design of reverse osmosis pretreatment system, if the total organic carbon (TOC) content in water exceeds 2 mg/L, it is generally necessary to add activated carbon to filter. For a purification system using tap water as a water source, activated carbon adsorption is necessary because the tap water is high in organic matter and contains a certain amount of free chlorine.
The function of the activated carbon filter is as follows:
Adsorbs organic substances in water, reduces color and odor in water, and prevents reverse osmosis membrane from being contaminated by microorganisms;
Remove free chlorine from the water to prevent it from oxidizing the reverse osmosis membrane.
The activated carbon filter device is composed of a steel filter tank, a water distribution device, a gas distribution device, an automatic control valve, a high-quality activated carbon and related accessory pipelines.
5. Precision filter
Also known as a security filter, its role is to retain particles larger than 5 microns in raw water to ensure that the reverse osmosis membrane is not scratched by the suspension of large particles.
Because the thickness of the reverse osmosis membrane is about 10 microns, the larger particles in the raw water are easily scratched by the high pressure pump, and the desalted skin layer on the surface of the reverse osmosis membrane is easily scratched and may even penetrate the reverse osmosis membrane module. A 5 micron precision filter is installed to ensure the safety of the reverse osmosis membrane.
In order to prevent fine suspended matter from entering the reverse osmosis system, causing fouling and surface scratching of the reverse osmosis membrane, a 5 micron precision filter is installed in front of the reverse osmosis unit.
