Forward osmosis filtration system for removing contaminants from algae water

Abstract

The application provides a forward osmosis filtration system for removing pollutants in algae water, which comprises a conductive forward osmosis membrane, a feeding device and a discharging device, the feeding device is used for containing original algae water to be separated, and the discharging device is used for containing algae water filtered through the conductive forward osmosis membrane, wherein a negative voltage is applied to the conductive forward osmosis membrane. The application can remove algae metabolites such as algal toxins, geosmin and dimethyl isocin alcohol to a high degree, and can alleviate membrane pollution to a certain extent; in the case of long-time operation, the removal efficiency of the three pollutants still remains high, stable chemical properties and forward osmosis properties are maintained, the physical and chemical properties and performance of the conductive forward osmosis membrane are not damaged, and the application has strong chemical practicability and excellent water treatment stability.
