Removal of nutrients from aquaculture residual water: A review

Aquaculture plays an important role in providing protein-rich foods, meeting the growing demand for fish. However, aquaculture is a potentially polluting activity, especially with regard to water pollution, due improper disposal of wastewater from production process. rich nutrients (ammonia, nitrate, nitrite and phosphorus) organic matter, commonly discharged into environment without proper treatment. This can cause series environmental impacts aggravate current crisis. Due importance need reduce impacts, plan use resources achieve efficient sustainable process, many researchers have focused their studies on effluent treatment techniques designed remove these nutrients. article therefore presents updated review main physicochemical biological used removal nutrients, which mitigate problems arising activities contribute sustainability activity.
