Electrochemical Water Treatment Systems
Engineered for industrial wastewater oxidation, disinfection, COD reduction, color removal, and difficult contaminant treatment. Hele Titanium provides MMO titanium anodes, BDD electrodes, PbO₂ electrodes, Ir-Ta MMO anodes, and custom reactor electrodes for advanced electrochemical water treatment systems.
Advanced Oxidation & Disinfection
Electrochemical water treatment uses electrical energy and specialized electrodes to generate oxidizing species directly in water, helping support disinfection, organic pollutant degradation, color removal, and difficult industrial wastewater treatment.
Water quality, conductivity, chloride concentration, COD level, pH, flow rate, current density, operating hours, and electrode coating stability directly affect treatment efficiency, energy consumption, maintenance needs, and system reliability. Hele Titanium supports these systems with MMO titanium anodes, BDD electrodes, PbO₂ electrodes, Ir-Ta MMO anodes, and custom reactor electrode assemblies.
For water treatment projects, electrode selection should be based on water source, target pollutant, conductivity, chloride level, treatment objective, reactor design, operating conditions, and documentation requirements.
Working Principle
In electrochemical water treatment, electrodes generate oxidizing species such as active chlorine, hydroxyl radicals, or other reactive oxidants depending on water chemistry and electrode material. These oxidants help support disinfection, organic degradation, COD reduction, and color removal.
How Electrochemical Water Treatment Works
Advanced Oxidation & Reactive Species Generation
Electrochemical water treatment generates oxidizing species inside a reactor using selected electrode materials and controlled electrical conditions. Treatment performance depends on water chemistry, electrode type, conductivity, chloride concentration, current density, and reactor design.
Wastewater Enters the Electrochemical Reactor
Water or wastewater flows through the reactor under controlled flow rate, conductivity, and residence time.
Electrodes Generate Oxidizing Species
MMO, BDD, PbO₂, or Ir-Ta electrodes generate active oxidants depending on water chemistry and operating conditions.
Pollutants Are Oxidized or Converted
Organic pollutants, color bodies, odor compounds, microorganisms, or selected contaminants are treated through electrochemical oxidation or disinfection pathways.
Process Conditions Control Treatment Results
Current density, voltage, pH, chloride level, conductivity, electrode material, and reactor geometry affect removal performance and energy use.
System Configuration
Typical Electrochemical Water Treatment System
A typical electrochemical water treatment system combines wastewater feed, electrochemical reactor cells, MMO / BDD / PbO₂ electrodes, DC power supply, flow control, oxidation contact time, gas management, and monitoring instruments to support targeted water treatment performance.
Buyer Note: Final reactor and electrode configuration depends on water quality, pollutant type, conductivity, chloride level, flow rate, current density, treatment target, and operating hours.
