Water Treatment

Industrial wastewater from sectors like pharmaceuticals, refining, mining, power and batteries contains toxic pollutants, dissolved solids, organics and radionuclides, requiring pretreatment before sewer discharge.

Electrocoagulation-flotation (ECF) offers better pollutant removal with less sludge, lowering disposal costs. Electrocoagulation produces coagulants in situ to destabilise contaminants, followed by electroflotation that floats pollutants via electrolytic H₂/O₂ bubbles.

Treatment efficiency depends on electrode material, pH and current density — our mixed metal-oxide coated anodes (titanium base with IrO₂/RuO₂) perform excellently at high current densities.

Untreated domestic wastewater contains ammonia, nitrogen and phosphorus compounds. Excessive nitrogen triggers environmental problems, ecological imbalance, algal blooms, water oxygen depletion and drinking-water pollution.

For environmental and health concerns, denitrification is essential to meet strict discharge standards. Unlike biological treatment, electrochemical denitrification features high efficiency, low cost and simple operation, converting nitrate nitrogen into harmless nitrogen gas for safe emission.

Electrochemical effluent treatment is highly effective due to the good conductivity of flue-gas desulfurization (FGD) wastewater and the presence of chloride ions, which facilitate electrochemical oxidation. It can oxidise organic pollutants directly at the electrode or indirectly in the bulk solution.

Utilising our on-site generator, it creates a system that helps you achieve a fundamental leap forward in capital efficiency, return on investment (ROI) and environmental protection — making FGD effluent treatment safer, more economical and more sustainable.

Untreated sewage contains toxins that harm health and the environment. Electrolytic processes outperform traditional methods for clarification, disinfection and phosphate removal — at lower cost and shorter detention time.

In an electrolytic cell, organics are oxidised at the anode, directly or via reactive species. Ruthenium-oxide coated titanium anodes are widely used for tertiary chlorination, efficiently reducing colour and COD.

Urban landfills dispose of domestic, industrial and commercial solid waste. Buried waste undergoes biological and physicochemical changes, and rainfall forms highly polluting landfill leachate that contaminates soil, surface water and groundwater — so proper treatment is vital to protect ecology and public health.

Among the available technologies, electro-Fenton (EF) is highly efficient: it generates hydroxyl radicals via hydrogen peroxide and ferrous ions to oxidise harmful pollutants, especially refractory micro-pollutants.

The electrochemical process for circulating water is an advanced technology that enables precise control of water hardness, alkalinity and chloride levels while capturing any vented chlorine gas.

Within the on-site generator, chloride ions released near the anode are converted into free chlorine, accompanied by trace amounts of ozone and hydroxyl radicals. These oxidising substances act on algae and fungi in the water, inhibiting bacterial growth and preventing the adhesion of biological slime. The captured chlorine gas is converted into sodium hypochlorite for reuse.

Limescale is prevalent in circulating water systems. Accumulated scale reduces water flow and heat transfer, raising energy consumption and lowering operational efficiency, making regular descaling necessary.

Electrolytic descaling works via water electrolysis: the cathode creates alkaline conditions that precipitate calcium, magnesium and other metal ions onto the electrodes, while oxidants generated at the anode restrain algae, fungi and bacteria and prevent biological slime formation.

Chlorine has long been the dominant sanitizer, eliminating pathogens by breaking their molecular chemical bonds. Electrochlorination serves as an efficient, adjustable alternative for water disinfection, widely used in drinking-water supply, wastewater treatment and swimming-pool sterilization.

It generates hypochlorous acid and sodium hypochlorite by electrolyzing brine with plate electrodes in reaction pipes. Electrode efficiency varies by material — titanium electrodes coated with IrO₂ or IrO₂/RuO₂ perform better than boron-doped diamond and platinum electrodes.

To ease water shortage, seawater desalination reliably supplies irrigation and drinking water by removing salt from seawater. As a superior alternative to traditional reverse osmosis, electrodialysis is a key electric-driven technology for large-scale brackish-water desalination.

It separates dilute water and concentrated brine via alternating anion-cation selective membranes. Electrode lifespan is influenced by operating current and water ion composition — with outstanding conductivity, metal-oxide coated titanium electrodes are perfectly suited for high-current, high-chloride desalination applications.
