| Abstract: | Air floatation process for the pretreatment of seawater desalination was studied with ferric chloride and polyaluminium chloride as coagulant,chlorine water as oxidant.The result showed that pre-oxidation could enhance the efficiency of coagulation+ air floatation process for the removal of turbidity,CODMn,UV254 and TOC.The optimal dosage for ferric chloride was 15~20 mg/L and 6~10 mg/L for polyaluminium chloride,and optimal reflux ratio of air floatation was 15%.The pretreatment process showed satisfied ef... |
