Common knowledge points reserve for water treatment
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.
