Recovering Valuable Phosphates: Chemical Biotechnology as a Problem Solver for the Environment
Keywords:Microbial fuel cell, Phosphate recovery, Phosphate remobilization, Sewage sludge, Struvite fertilizer
AbstractResearchers from the HES-SO Valais/Wallis have demonstrated how to extract phosphate from sewage sludge on the laboratory scale using renewable energy sources from a microbial fuel cell. The mobilized phosphate barely contains heavy metals and can be used to produce fertilizer of marketable quality. The necessary energy comes from a sewage treatment plant and causes no additional costs.
