DESCRIPTION
PAC POWDER is a polymeric compound of chlorinated aluminium hydrate, generally
known as polyaluminium chloride (PAC). When utilizing PAC POWDER, considerable
technical and economic benefits can be achieved, based the chain length of polymer,
high number of positive electric charges and high molecular weight; as compared
with conventional flocculants such as aluminium sulphate, ferric chloride or
ferric sulphate.
