By Shreyansh Shah, Director, at LEXCRU Water Tech Pvt. Ltd Sanalkumar, Associate Vice President, at LEXCRU Water Tech Pvt. LtdZuo Jian, Co-founder, at SideStroem Water Technologies Pte. Ltd The growing need for ZLD Access to clean water is no longer a certainty—it’s an emerging fault line of global stability. In 2024, São Paulo narrowly avoided a second major “Day Zero” as drought once again pushed its reservoirs to historic lows. Kenya is facing its worst water crisis in 40 years, affecting millions with a lack of clean water and food while…

Why are ZLD processes on the rise? Access to water is no longer assured. Cape Town narrowly averted “Day Zero” amid intense public scrutiny during a 2018 drought. In June 2019, the 11 million residents of Chennai, India, endured a day without drinking water, and in 2020, the towns of Stanthorpe and Clifton in Queensland, Australia, both experienced water depletion. These incidents are not isolated and are projected to escalate as climate change effects intensify. When faced with systemic risks to economic growth and public health, the economic implications of…

TERI, Dew Projects & Chemicals to commercialise TADOX technology for wastewater treatment

eawater

The Energy and Resources Institute (TERI) signed the TADOX Technology and Trademark License (TTLA) agreement with Dew Projects and Chemicals, Noida, for the commercialization of TERI’s patented wastewater treatment technology for municipal and industrial wastewater treatment and reuse in New Delhi. The economics of adequate treatment of wastewater, reuse and mandate to achieve zero liquid discharge (ZLD) has long been a challenge for industries. Advanced oxidation technologies like TADOX offer an economically viable and widely applicable solution to tackle the problem by making the process sustainable and energy efficient, noted…

Zero Liquid Discharge, Policy Scenerio and Indian Textile Industries

eawater

By Manoj Nainani, Executive Director, Egis India Over the years, growth of population, expansion of industry and infrastructures has resulted in accelerated depletion of the natural water supplies and created water stress regions around the world. Further, to preserve natural resources from overburdening and pollution; stringent environmental regulations are being enforced. This requires additional technology interventions prior to waste water discharge and to undertake water management practices. Zero Liquid Discharge (ZLD) is a comparatively recent development in waste water treatment that totally eliminates requirement of waste water discharge to the…
