Processing of the liquid fraction
Electrochemistry
Objective
Processes that use sacrificial anodes and stable anodes to promote the chemical precipitation of compounds of interest.
Inlets
Liquid streams rich in N-ammoniacal and/or P-orthophosphoric
Efficiency
.
Weaknesses
Co-precipitation of CaCO3 when looking for the direct recovery of P by pH modification;
The energy requirement is inversely proportional to the electrical conductivity of the water;
The energy requirement is inversely proportional to the electrical conductivity of the water;
Products
Mg sacrificial anodes induce struvite precipitation. In ammonia adsorption processes, if sulfuric acid is used, ammonium sulfate salts will be produced
