2、 Equipment Process Description

1. Raw water pump

Main function: Constant system water supply pressure, stable water supply volume.

2. Manganese sand filter

The main purpose of using a filter with multiple filtration layers is to remove particles such as sediment, iron and manganese, colloidal substances, suspended solids, etc. contained in the raw water20umThe above substances can be subjected to a series of operations such as backwashing and forward flushing by the system.

Main function: Ensure the quality of water produced by the equipment and prolong its use

3. Activated carbon filter

Using a fruit shell activated carbon filter, activated carbon can not only adsorb electrolyte ions, but also perform ion exchange adsorption. Adsorption by activated carbon can also increase the oxygen consumption of potassium permanganate（COD）By15mg/L(O2)drop to2~7mg/L(O2)In addition, due to the adsorption effect, the concentration of surface replication is increased, which also plays a catalytic role in removing pigments, odors, a large amount of biochemical organic matter, reducing residual chlorine and pesticide pollutants in water, and removing trihalides from water（THM）And other pollutants. The system can perform a series of operations such as backwashing and forward flushing. At the same time, the equipment has a self maintenance system and low operating costs.

Main function: Ensure the quality of water produced by the equipment and extend its service life.

4. Softening system

To prevent the concentration of concentrated water, especiallyROThe concentrated water side of the last membrane component of the device appearsCaCO3，MgCO 3，MgSO4，CaSO4，BaSO4，SrSO4，SiSO4Crystallization occurs when the concentration exceeds its equilibrium solubility constant,Characteristics of Damaged Membrane Components,Install a scale inhibitor dosing system before entering the reverse osmosis membrane module.

The system includes: dosing pump, dosing tank, and water level switch.

Main function: To prevent scaling of reverse osmosis membranes and extend their service life.

5. Security filter

Precision filters are used to intercept small amounts of mechanical impurities that have leaked through the pre-treatment system. The filter cylinder is made of engineering plastic orSUS304material contentsPPFfilter element. Polypropylene filter cartridge is a deep filtration element with high efficiency and low resistance. Suitable for low levels of suspended impurities (turbidity less than)2-5Further purify the water. The polypropylene filter element is formed by winding polypropylene fibers in a certain pattern around an injection molded polypropylene porous tube.

6.Reverse osmosis: filtration accuracy is0.0001About micrometers, it's the United States60A high-precision membrane separation technology utilizing pressure difference developed in the early years. It can filter out almost all impurities (including harmful and beneficial) in water, allowing only water molecules to pass through. It is generally used in the production of purified water, industrial ultrapure water, and pharmaceutical ultrapure water. It can effectively remove heavy metals and other carcinogenic microorganisms from water, while retaining a small amount of beneficial mineral elements for the human body. It is currently the most high-end water treatment method on the market.

Main function: Ensure that the particle size of water entering the reverse osmosis membrane is less than0.1um.
