30T/D Pickling Phosphate Wastewater Treatment Equipment

30T/D pickling phosphate wastewater treatment, ultrafiltration water treatment

Scope of application
Ultrafiltration membrane technology is not only used in drinking water treatment and domestic sewage treatment, but also used in the treatment of circulating sewage from power plants, the treatment of circulating sewage from cooling in mining areas, the treatment of pulp and paper bleaching wastewater, and the treatment of industrial wastewater such as sewage from iron and steel enterprises.

UF Work Principle:

The Ultrafiltration is used to screening as separation principle ,that is process of membrane separation with the pressure ,the precision of filtration is in 0.005-0.01μm range,which can effectively remove particles ,colloids ,bacteria ,pyrogen and high polymer organic matter in water .It can be widely applied to the separation ,concentration,purification of substances .The Ultra filtration Process has no phase inversion , operation under normal temperature.It is better to separate for pyrogen ,and have good resistance heat ,resistance acid &alkali and oxidation resistance ,and it is continuously used under 60℃ and PH 2-11 for a long time.

Pickling and phosphating process
It mainly removes various metal ions in sewage. Therefore, the main body adopts a coagulation reaction tank and supplements OH- to the sewage to adjust the pH of the sewage and form solid precipitates with zinc and iron ions in the water. At the same time, anionic PAM is added at this stage to mix monohydrogen phosphate and dihydrogen phosphate ions with metal cations such as aluminum, iron and calcium, and remove them as solid precipitates.
