Raw water is groundwater: sand filter+precision filter+reverse osmosis+mixed bed or EDI

Common water treatment processes

1. Raw water is groundwater: sand filter+precision filter+reverse osmosis+mixed bed or EDI

2. Raw water is tap water: sand filter+activated carbon filter+precision filter+RO+mixed bed or EDI

3. Surface water:

① Multi media filter+activated carbon filter+precision filter+RO+mixed bed or EDI

② Multi media filter (or other form of filter)+ultrafiltration+precision filter+RO+mixed bed or EDI

③ Disc filter+ultrafiltration+precision filter+RO+mixed bed or EDI

Commonly used pipeline materials in water treatment engineering

Carbon steel pipe: used for raw water inlet pipeline.

UPVC pipe: It is better for applications with a diameter less than DN150 and is easy to install.

Stainless steel tube: Used for special requirements, mostly for small systems in medicine and pharmaceuticals.

Steel lined rubber or plastic pipe: used in large engineering projects, reliable in use, and difficult to construct.
