sand filter, sand filter for water filter machine, automatic back washing water filter

1.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.

2.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.

3.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:

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

4.Ion 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 of dia32 clear plastic tubes for some when use it ,732 ion 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.

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

 Sand filter, sand filter for water filter machine, automatic back washing water filter

This sand filter, active carbon filter, ion exchanger will be widely used in water treatment, it can remove smell and residue, odd, color of water. It is used to improve quality  and enhancing input water index of RO membrane.
