1. Raw water tank, function: store system raw water, regulate the inflow, and also have a certain sedimentation effect on impurities in the inflow
2. Raw water pump: Function: Constant system water supply pressure, stable water supply volume.
3. Flocculation dosing system: Function: By adding coagulants, water coagulation impurities can be quickly precipitated.
4. Sand filter, function: preliminarily remove sediment, impurities, suspended solids, and other particles from water to reduce water turbidity.
5. Carbon filter, function: using the adsorption principle of carbon to adsorb color, odor, residual chlorine, etc. in water.
6. Softener, function: Use specialized resin for soft water to adsorb and replace calcium and magnesium ions in water, reduce water hardness, prevent calcium and magnesium ions from combining with carbonate and sulfate ions, and prevent scaling in downstream water treatment equipment or pipelines.
7. Security filter, function: prevent large particle impurities from entering the reverse osmosis membrane, causing damage to the membrane, and protect the reverse osmosis membrane.
8. Primary high-pressure pump: Function: Provide stable pressure for the reverse osmosis system
9. Primary reverse osmosis: Function: Effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water through membrane components to produce pure water. The desalination rate of reverse osmosis equipment can reach over 98%, and it can also remove bacteria, viruses, colloids, organic matter, and more than 98.6% of soluble roots in water
10. Intermediate water tank: Function: Store the first stage reverse osmosis water and provide water for the second stage reverse osmosis system
11. Secondary reverse osmosis: Function: Use the water produced by primary reverse osmosis as raw water for secondary reverse osmosis purification. Make the conductivity ≤ 2 μ S/CM to achieve the goal of producing pure water. Secondary reverse osmosis can ensure the quality of the produced water to the greatest extent possible, making the EDI produced water more stable and prolonging the service life of the polishing resin.
