Pre treatment of industrial pure water

 

When producing industrial pure water, pure water equipment will determine whether water pretreatment is necessary based on the quality of the incoming water. Let's learn about the function of industrial pure water pretreatment and which device is used for water pretreatment?

 

The hardness of the raw water used in industrial pure water equipment varies depending on the region, so some regions require water pretreatment before water treatment.

 

The raw water is filtered through activated carbon filters or quartz sand to remove fine suspended particles remaining in the clean water. After pre-treatment, the water can enter the circulating cooling water treatment system.

 

The water quality M Ω· cm of industrial pure water equipment is between 0.5M Ω· cm and 18.2M Ω· cm, and its water treatment process is based on the effluent water quality:

 

EDI water treatment process flow: raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → primary reverse osmosis machine → intermediate water tank → intermediate water pump → EDI system → microporous filter → water user.

 

Reverse osmosis water treatment process flow: raw water → raw water booster pump → multi-media filter → activated carbon filter → water softener → precision filter → first stage reverse osmosis → pH adjustment → intermediate water tank → second stage reverse osmosis (with positive charge on the surface of the reverse osmosis membrane) → purified water tank → pure water pump → microporous filter → water user.

 

Pre treatment of raw water can to some extent reduce the error in the effluent of pure water equipment, and can also extend the service life of the equipment.
