We studied phosphorus removal for small-scale wastewater treatment systems using the electrochemical elution of iron.The efficiency of this method to remove phosphorus is better than chemical precipitation of ferric chloride, and is affected by the Fe:P ratio and the influence of calcium ion and magnesium ion concentrations. In laboratory tests combining an electrolytic bath and biofilter, we succeeded in removing over 90% of the phosphorus while maintaining the Fe:P ratio at 1.5.This method can control the iron elution concentration easily, and is available to remove phosphorus from small-scale wastewater treatment systems.
