Energy Recovery Wins Five New Wastewater Projects Across India's Industrial Sector

Energy Recovery has announced five new contracted wastewater projects in India spanning the textile, photovoltaic manufacturing, steel and petrochemical refining industries, with multiple PX Pressure Exchanger energy recovery devices to be installed in industrial reverse osmosis plants representing a cumulative 30,000 cubic metres per day of capacity. The new orders bring Energy Recovery's total supported industrial wastewater treatment capacity in India to more than 230,000 cubic metres per day across over 50 wastewater projects, reflecting growing commercial traction in a market where water demand is projected to be twice the available supply by 2030. All five new orders are for zero-liquid discharge systems, a wastewater treatment process that eliminates all liquid waste from industrial facilities but is typically energy-intensive, with Energy Recovery's devices significantly reducing the electricity required to operate these systems.

 

India's Water Stress Driving Industrial Treatment Demand

 

India's structural water scarcity, with approximately 18 percent of the global population sharing only 4 percent of the world's freshwater resources, creates an acute and worsening supply-demand imbalance that is driving regulatory and commercial pressure for industrial water reuse across the country's most water-intensive sectors. The projection that water demand will reach twice the available supply by 2030 provides the structural urgency behind India's tightening wastewater discharge regulations and the growing industrial adoption of reverse osmosis treatment strategies that the new Energy Recovery contracts serve. The diversity of industries represented in the five new project wins, spanning textile manufacturing, photovoltaic panel production, steel and petrochemical refining, demonstrates that water stress-driven treatment investment is occurring across India's industrial base rather than being concentrated in a single high-visibility sector, reflecting the breadth of regulatory and resource scarcity pressure facing Indian manufacturers.

Zero-liquid discharge systems represent the most stringent standard of industrial wastewater management, eliminating all liquid waste discharge from a facility by treating and recycling effectively all process water, but the energy intensity of achieving this standard through reverse osmosis has historically represented a significant operating cost and emissions burden for adopting facilities. David Kim-Hak, Vice President of Wastewater at Energy Recovery, said India is moving quickly toward water reuse and zero-liquid discharge, creating real pressure on the energy economics of industrial water treatment, and that operators across these industries are now designing energy recovery devices into their systems from the start rather than retrofitting efficiency improvements after initial system design.

The PX Pressure Exchanger Technology and Energy Efficiency

 

Energy Recovery's PX Pressure Exchanger technology operates at up to 99 percent efficiency with a single moving part, capturing pressure energy from the reverse osmosis process that would otherwise be lost and returning it to the system, substantially reducing the electricity input required to drive the high-pressure pumping that reverse osmosis treatment demands. This pressure energy recovery is particularly valuable for zero-liquid discharge applications, where the multiple sequential treatment stages required to achieve complete liquid elimination compound the energy intensity challenge that conventional reverse osmosis systems already face, making energy recovery technology integration increasingly commercially essential rather than merely advantageous for facility operators managing both regulatory compliance costs and energy expenses. Kim-Hak said bringing the proven efficiency and reliability of PX technology to these applications helps operators lower operating costs and emissions while reducing exposure to volatile power prices, connecting the water treatment energy efficiency benefit directly to broader energy cost and price volatility management objectives that industrial facility operators prioritise.

The single moving part design underlying the PX technology's reliability is commercially significant for industrial customers because it minimises maintenance requirements and the risk of mechanical failure that could compromise continuous wastewater treatment operations, a critical consideration for facilities where treatment system downtime can halt production or create regulatory compliance breaches. The technology's three-decade origin in the desalination industry provides Energy Recovery with an extensive track record of pressure exchanger reliability across large-scale water treatment applications before its adaptation to the industrial wastewater treatment market that the India contracts represent.

Outlook for Industrial Water Treatment Technology in India

 

The growth from supporting wastewater treatment projects to over 230,000 cubic metres per day capacity across more than 50 projects in India demonstrates Energy Recovery's establishment of a meaningful commercial position in one of the world's most significant industrial water treatment growth markets, where the structural water scarcity driving regulatory and operational pressure shows no sign of easing given continued industrial growth and population expansion. Whether Energy Recovery can continue capturing market share as India's industrial sector accelerates adoption of zero-liquid discharge and water reuse technologies will depend on the company's ability to scale technical support and project delivery capacity to match the pace of new project commissioning across the diverse industrial sectors now adopting its technology. Sustained growth in India's industrial water treatment energy efficiency technology adoption would provide a meaningful contribution to reducing the energy intensity, and associated emissions, of the water treatment capacity that India's worsening water scarcity makes increasingly essential across its manufacturing economy.
