water storage tank/water treatment

Water treatment equipment

One-stage osmosis purifying water equipment

One-stage reverse osmosis

Original water(tap water, surface water,underground water) pass pretreatment ,sophisticated filter,and then sent to reverse osmosis by high pressure pump to produce pure water directly that is known as one-stage reverse osmosis.

One-stage reverse osmosis is suitable for the original water with conductivity less than 500 us/cm and conductivity of output water is 1-10 us/cm.

Two-stage osmosis purifying water equipment

The original water(tap water,surface water, underground water) is sent to pretreatment system by adding pressure to be filtered roughly, then to be filtered by sophisticated filter,after that the water is transmitted to primary reverse osmosis by one-stage high pressure pump to be filtered, then the water is added pressure again by secondary high pressure pump and sent to second reverse osmosis system to produce the product water, that is called two-stage reverse osmosis.

Original water conductivity>500us/cm,purified water conductivity:1-10us/cm

Ultra Filtration Mineral Water Equipment

Ultrafiltration

Normally the ultrafiltration is used to produce mineral water and spring water.Driven by pressure,it is a process of discharging impurity through different diameter hole on the ultrafiltration membrane. At present, the hollow-fiber type of polysulfones are widely used in water treatment industry.
