        The main targets of pretreatment are suspension, mechanical waste such as viscose debris particles, colloidal silica, microorganisms, active chlorine, and organic substance, which have an adverse impact on the follow-up treatment. The result of pretreatment directly affects technical and economic effect and long-term safe operation of electricity dialysis, reverse osmosis, ion exchange and so on. It is an important stage in water treatment.

Product introduce:

1.original tank(depending on the circumstances to select)

Overcome the instability of the water supply pipe network. Ensure that the entire system of water supply stable and continuous. It can be providing a guarantee to the reliable performance of the device long-term also. Control (depending on the circumstances to select). Preparations high float valve. Control switch when the water level is not in high, with raw water solenoid valve open condition, when the water level in the high-water, solenoid valve is closed, when the water level in the low water level, the raw water pump stop working, protection of the original water pump.

2.raw water pump

Provide the necessary pressure to all pretreatment equipment. According to pretreatment equipment design pressure drop. Maximum pressure on each piece of equipment can not be less than 0.5MPa.determine the original water pump working pressure.

3.Quartz sand filter

Containing very fine particles of dust, humus, starch, cellulose and bacteria, algae and other microorganisms, these impurity particles with water to form the body of the sol state, showing the sedimentation stability and aggregate stability, due to Brownian motion and electrostatic repulsion usually can not use the gravity of natural sedimentation to remove. There by reducing the turbidity of the water. The quartz sand is made from natural quartz by crushing, washing, drying, and second filter, no impurities, no angle, density, high mechanical strength contained sewage capacity line to use the long cycle. It is a good material for chemical water treatment.

4.activated carbon filter

Reverse osmosis water in addition to the requirements of SD1<5. but also have another water indicators of residual chlorine<0.1mg/L. The activated carbon filter has two functions:

1. Adsorption of part of the organic matter, absorption rate of about 60%.

2. Adsorption of residual chlorine in the water. Inorganic colloidal partied size of about 10-20 angstroms. Organic colloidal and dissolved organic polymer impurities in the media filter is difficult to remove.

5.Lon exchanger

Sodium ion exchange ion exchange resin of Na+ to replace the water of Ca2+,Mg2+ to the water hardness <0.035 milligram/L. the raw water hardness decreased become soft water. Sodium ion exchanger made by ion exchange tanks adapter. Central tube, water inlet and outlet, it needs to purchase a plastic pump and inner diameter ofφ32 clear plastic tubes for some when use it ,732 Lon exchange resin 75-150 kg for supporting the use of switches, before use by adding 732 ion exchange resin cylinder adapter for threaded connection, it can be add material and disassembly. Pipe device for the input source, brine, output soft water, and diarrhea put wastewater installations

.pipeline is equipped with cutoff valves, for controlling the flow of water. It can provide output value of soft water to users.
