Archroma, a global leader in sustainable specialty chemicals, partnered with Gradiant to deploy a high-efficiency, membrane- and oxidation-based ZLD solution, reinforcing its commitment to responsible water management in the textile industry. Located in a water-stressed region near Bangkok, the Mahachai plant now serves as a model for sustainable textile dye production, significantly reducing reliance on local water supplies while improving environmental resilience.

As part of its broader sustainability endeavor, Archroma addresses critical challenges within the apparel and textile industry, particularly water consumption. “We believe in reducing water use in production and home laundering. We innovate to remove toxins and contaminants from our products, making wastewater treatment easier for our plants and customers,” said Dhirendra Gautam, VP Global Marketing and Strategy, Archroma. “Our goal is to require our plants to have effective water conservation facilities with special focus on water stressed areas, contributing to water conservation and helping to combat acute water scarcity worldwide.”

Since 2019, Archroma has evaluated various ZLD solutions to address growing water challenges in Thailand. Gradiant’s Counterflow Reverse Osmosis (CFRO) was selected as the preferred technology for its ability to treat diverse wastewater compositions with superior efficiency and minimal energy consumption. The modular system seamlessly integrates with the plant’s existing wastewater treatment infrastructure, maximizing desalination capacity and water recovery while reducing the plant’s environmental footprint.

In addition to CFRO, Gradiant’s Free Radical Oxidation (FRO) technology has been deployed to remove color and organics from the RO concentrate, ensuring safe discharge and meeting stringent environmental regulations. The system also enables the recovery of concentrated brine, which Archroma repurposes within the dyeing process or supplies to industry partners for applications such as resin regeneration and chlorine production, further promoting a circular economy in water and resource management.

“Water-intensive industries are under increasing pressure to adopt responsible solutions, and this partnership with Archroma demonstrates how advanced water treatment can drive sustainability without compromising operational efficiency,” said Prakash Govindan, COO of Gradiant. “Our ZLD solution at Mahachai leverages innovative membrane and oxidation technologies to maximize water recovery, reduce environmental impact, and create valuable resource streams. We are proud to support Archroma’s commitment to sustainable manufacturing and water stewardship.”

Thailand faces mounting water stress due to climate change, extreme droughts, and aging infrastructure, making sustainable water management an urgent priority. By implementing Gradiant’s ZLD solution, Archroma significantly reduces its dependence on freshwater sources, ensuring long-term operational resilience in a resource-constrained environment.

This multi-million-dollar investment underscores Archroma’s dedication to water conservation and its broader mission to transform the textile industry through sustainable innovation. Beyond Thailand, Archroma continues to expand its ZLD initiatives globally, including its Sustainable Effluent Treatment (SET) plant in Jamshoro, Pakistan, which has been providing irrigation water to surrounding communities.

By partnering with Gradiant, Archroma reaffirms its commitment to employing innovative solutions that drive economic, environmental, and industrial sustainability on a global scale.
