Charged! Water purification with electricityTheme
Energy & Nutrient Factory, Innovation / new techniques
During electrocoagulation, iron plates are charged which causes the iron to dissolve. The charge of the pollutants is neutralized by the dissolved iron letting the particles coagulate and finally settle. Electrocoagulation can replace dosage of iron(III)chloride, possibly making iron dosing more safe and decreasing the CO2 footprint of the process. Electrocoagulation removed COD, bacteria, metals and nutrients.
The electrocoagulation process step will be further optimised and several strategies will be tested to recover the resources from the produced electrocoagulation sludge.
First, the system will be further optimised for the produced effluent to serve as influent for the next process step nanofiltration. Next to that, the CO2 footprint and energy consumption will be determined.
