TADOX

Ion Exchange (India) Ltd. and a leading Indian research organisation focused on energy and environment entered into an INDION® TADOX® Technology and Trademark License Agreement in February 2024, commercialising the organisation’s patented wastewater treatment technology for industrial applications. The technology can be integrated at the secondary treatment stage, prior to membrane processes, or at the pre-biological stage of a treatment train.

INDION® TADOX® is an Advanced Oxidation Process (AOP) built on a patented photocatalysis principle. It drives oxidative degradation and mineralisation of targeted pollutants, removing colour, dissolved organics and recalcitrant organics (RCOD) from wastewater streams, while reducing the chemical dosing and sludge volume conventional physicochemical processes require.

How It Works

A patented photocatalysis process generates highly reactive oxidising species when exposed to light, which attack and break down complex organic pollutant molecules — including recalcitrant compounds that resist conventional biological or physicochemical treatment.

Applied at the pre-biological stage, TADOX helps downstream biological systems tolerate shock loads, removes toxicity and colour, and improves biodegradability before the stream reaches secondary treatment. Applied at the secondary stage instead, it improves membrane life and reduces the load reaching downstream tertiary treatment or multi-effect evaporation.
