At present, the water quality (tap water or groundwater) often fails to meet the current standards for food water. After being treated by the reverse osmosis equipment, it can meet the water quality requirements. 

Single-stage reverse osmosis equipment process flow 

Water source- raw water tank - raw water pump- quartz sand filter- activated carbon filter- scale inhibitor dosing system (or cation water softener)- precision filter- high-pressure pump- reverse osmosis system- finished water tank 

Double-stage reverse osmosis equipment process flow 

Water source- raw water tank- raw water pump- quartz sand filter- activated carbon filter- scale inhibitor dosing system (cation water softener)- precision filter- single-stage high-pressure pump- primary reverse osmosis system - intermediate water tank- two-stage booster pump- two-stage high-pressure pump- two-stage reverse osmosis system- finished water tank
