Industrial wastewater treatment has reached a revolutionary turning point with the advent of ELCOGEN™, LN Indtech’s groundbreaking chemical-free water treatment technology. This innovative solution represents a paradigm shift from traditional chemical-intensive treatment methods, offering industries a sustainable, cost-effective approach to wastewater management while achieving exceptional purification results.

The Science Behind ELCOGEN™

ELCOGEN™ operates on a sophisticated combination of Electrocoagulation (EC), Electrooxidation (EO), and Electroflotation (EF) coupled with Advanced Nano Bubbles and Hydrodynamic Cavitation systems. This integrated approach generates cleaning and purifying agents in situ, eliminating the need for external chemical additives while maintaining superior treatment efficacy.

The technology works by generating coagulants and powerful oxidants including hydroxyl radicals (OH°), oxygen (O), ozone (O3), and chlorine (Cl2) directly within the treatment system. These highly reactive species are produced through electrochemical processes that occur when electrical current passes through the wastewater, creating the ideal conditions for comprehensive pollutant removal.

The electrocoagulation process involves the dissolution of sacrificial electrodes, typically made of aluminum or iron, which release metal ions that act as coagulants. Simultaneously, electrooxidation generates powerful oxidizing agents that break down complex organic compounds and neutralize harmful contaminants. The electroflotation component creates fine bubbles that enhance the separation of suspended particles and oils from the treated water.
