Abstract
Phosphorus is removed from water to be treated by immersing electrodes into a tank filled with the water to be treated, applying a DC voltage between the electrodes to generate hydroxide ions through a cation migration in the water and/or an electrolysis, and precipitating phosphate ions in the water as a salt slightly soluble in water.
Claims16
A method for removing phosphorus from water to be treated, which comprises immersing a multi-electrode system into a tank filled with the water to be treated, applying a DC voltage to the multi-electrode system to generate hydroxide ions through a cation migration in the water and/or an electrolysis, and precipitating phosphate ions in the water as a salt slightly soluble in water,
- wherein the multi-electrode system is an operation system in which plural cathodes are arranged to a single anode, or plural anodes are arranged to a single cathode, and each electrode can be operated independently.
