Combination of agricultural by-products and electrocoagulation to recover and remove nutrient in domestic wastewater
Phosphorus security is emerging as one of the twenty-first century’s greatest global sustainability challenges. The main natural phosphorus resource is phosphate rock which is a non-renewable resource. Due to the high demand of phosphorus for human activities, the natural cycle of phosphorus has been opened and the mobile phosphorus in the environment has been ending up in natural water bodies, which causing eutrophication in these water bodies. Many studies have been conducted recently focusing on recover phosphorus from waste streams in both solid phase and liquid phase by utilizing different methods. This research aims to study the feasibility of recovering phosphorus, along with nitrogen, calcium, and magnesium in form of calcium phosphate and struvite by utilizing an integration of selective electrodialysis and pellet reactor on multiple waste streams, such as effluent of WWTP, brines, RO concentrate, … The products are calcium phosphate and struvite, which has potential application in industrial and agriculture, respectively.
