Raw water (tap water, surface water, underground water) pass quartz sand filter, active carbon filter, softening filter, and then sent to reverse osmosis by high pressure pump to produce pure water directly is known as one-stage reverse osmosis.
Hollow Fiber Ultra Filtration System For Mineral Water
Normally the ultra-filtration is used to produce mineralized water and spring water. Driven by pressure, it is a process of discharging impurity through different diameter hole on the ultra-filtration membrane. At present, the hollow-fiber type of polysulfones is widely used in water treatment industry.
