Double stage reverse osmosis, also known as secondary reverse osmosis, refers to the process in which the permeate water from the first stage of reverse osmosis is adjusted in pH value and then pumped into the second stage reverse osmosis system for treatment by the second stage high-pressure pump, thereby obtaining permeate water.
technological process:
Raw water → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → Primary reverse osmosis → PH adjustment → Intermediate water tank → Secondary reverse osmosis → Pure water tank → Pure water pump → UV sterilizer → Water point
