Ammonia removal from aquaculture wastewater by high flux and high rejection polysulfone/cellulose acetate blend membrane

Polysulfone (PSf)/cellulose acetate (CA) blend membranes with diferent compositions (100/0, 90/10, 85/15, 80/20, 75/25 and 70/30) were prepared and characterized for removal of low concentration ammonia (1–10 mg/L) from aquaculture wastewater. The performance of prepared membranes in terms of pure...
