Recovery of phosphorous from swine wastewater through crystallization.
All the phosphate rock Japan needs must be presently imported from abroad because the country has no subterranean phosphorous resources. Therefore, there is a need to accelerate the development of and establish the technologies for phosphorous recovery from waste and wastewater. Swine wastewater has a high potential for phosphorous recovery in Japan. A reactor for removing and recovering phosph...
متن کاملAssessment of Phosphorus Recovery from Swine Wastewater in Beijing, China
The nutrient management of phosphorus (P) contained in swine wastewater is an important challenge to enhance P use efficiency. In the present study, assessment of P recovery from swine wastewater in Beijing was performed. P amounts of swine wastewater increased from 11,687 tons in 1980 to 16,237 tons in 2014. Without treatment of swine wastewater, P concentration will reach a maximum 1.20 mg/L....
متن کاملRemoval and recovery of phosphorous from swine wastewater by demonstration crystallization reactor and struvite accumulation device.
A demonstration crystallization reactor and struvite accumulation device for the removal and recovery of phosphorous was constructed and their performance was evaluated using actual swine wastewater for 3.5 years. The wastewater pH was increased by aeration, and the concentrations of total P and soluble PO(4)-P were reduced by a struvite crystallization reaction induced under a high pH conditio...
متن کاملApplication of Magnesium Modified Corn Biochar for Phosphorus Removal and Recovery from Swine Wastewater
The recycling of lost phosphorus (P) is important in sustainable development. In line with this objective, biochar adsorption is a promising method of P recovery. Therefore, our study investigates the efficiency and selectivity of magnesium modified corn biochar (Mg/biochar) in relation to P adsorption. It also examines the available P derived from postsorption Mg/biochar. Mg/biochar is rich in...
متن کاملRemoval and recovery of phosphorus as struvite from swine wastewater using microbial fuel cell.
Air-cathode single chamber microbial fuel cells (MFCs) were operated with swine wastewater. The maximum power density, the maximum current density, the average value of COD-removal efficiency, and the coulombic efficiency were 1-2.3 W/m(2), 6.0-7.0 A/m(2), 76-91%, and 37-47%, respectively. During operation, 70-82% of the phosphorus was removed from the influent, and some precipitations were obs...
