High concentration sewage electrochemical flocculation

Description:
The core of electrochemical flocculation is to achieve the removal of pollutants through direct current driven electrode reactions, mainly involving three major functions:

Flocculation effect、Air flotation effect、Oxidation-reduction reaction

Development trend:

New electrode materials: Develop passivation resistant and low consumption electrodes (such as aluminum titanium composite electrodes and iron-based coated electrodes) to extend their service life.
Reactor optimization: Design efficient mass transfer structures (such as three-dimensional electrode reactors), or combine agitation and aeration to enhance the contact between pollutants and flocs.
Process combination: Combined with biological treatment (such as EC+A/O) and membrane separation (such as EC+UF) to reduce treatment costs and improve effluent quality.
Intelligent control: Real time monitoring of water quality through sensors, automatic adjustment of parameters such as current and pH, achieving low energy consumption and efficient operation.
