POLY ALUMINIUM CHLORIDE (P.A.C) (LIGHT YELLOW) | CÔNG TY TNHH
– P.A.C is used to treat water, wastewater in numerous industries including: textile dyeing, paper pulp and paper. Advantages of P.A.C: – High pH stability and adjustable pH in treatment, thus, chemicals used to increase alkalinity for attached equipment such as metering pumps and chemical container will be saved compared to using alum.
Decolouration of dyehouse effluent by activated carbon
They are produced on a large scale and may enter the environment during their manufacture or later on during textile dyeing. Due to the stability of modern dyes, conventional biological (activated sludge treatment) methods for industrial wastewater are ineffective, resulting in an intensively coloured discharge from the treatment facilities.
Instead Alum Use Poly Aluminium Chloride Coagulant in Water
3. In water treatment processes is the reduced concentration of sulphate added to the treated water.This directly affects SO 4 levels in domestic wastewater. 4. Low levels of residual aluminium in the treated water can be achieved, typically 0.01-0.05 mg/L. 5. Less sludge is produced compared to alum at an equivalent dose, 6.
