Abstract

We studied phosphorus removal for small-scale wastewater treatment systems using the electrochemical elution of iron.<br>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.<br>This method can control the iron elution concentration easily, and is available to remove phosphorus from small-scale wastewater treatment systems.
