The process of secondary reverse osmosis equipment is generally: quartz sand+activated carbon+security filter+primary reverse osmosis membrane+secondary reverse osmosis membrane.
However, according to the water quality and water production standards, some working procedures will be added. For example, there are many bacteria in the water, so it is necessary to add an ultraviolet sterilizer; If the water quality is hard, softening process or scale inhibition process will be added; If ultra-pure water is prepared, EDI module or polishing resin will be added later.
