WINNER special nanofiltration NF membrane technology, the introduction of European and American technology, focused on sewage acid, alkali in the purification of resources recovery. Compared with the traditional neutralization-coagulation-sedimentation process, on the one hand, the addition of the neutralization agent and the production of waste salt at the end can be reduced, and on the other hand, the purified acid-base can be reused in the production to realize the change from cost to profit.
Typical acidic solution:
?20% H2SO4 sulfuric acid

?10% sodium hydroxide
?20% sodium hydroxide
?20% potassium hydroxide
Case study:
? Recovery of lye (sodium hydroxide, potassium hydroxide)
? Recovery of metals from Lye
? Recovery of Electrolytes
? Reduction of COD in waste liquor
? Recovery of lye used to clean containers and equipment
? Some routine applications that require cleaning with caustic soda
