Energy Recovery (NASDAQ: ERII) announced five new contracted wastewater projects across India, each employing its PX® Pressure Exchanger® (PX) devices in industrial reverse osmosis (RO) plants. The orders add roughly 30,000 m³ per day of zero‑liquid‑discharge (ZLD) capacity and bring the company’s total support in India to over 230,000 m³ per day, underscoring growing demand for energy‑efficient water‑reuse solutions.
New Indian Contracts Expand PX Deployment
The five contracts cover textile, photovoltaic manufacturing, steel, and petrochemical refining facilities, all of which are subject to India’s tightening wastewater discharge regulations. Each project will install multiple PX pressure exchangers to recover energy from the high‑pressure side of the RO process and feed it back to the low‑pressure side, reducing the electricity required for ZLD operation. Energy Recovery’s PX technology operates at up to 99 % efficiency with a single moving part, a claim the company repeats in its product literature. The cumulative capacity of the new projects is 30,000 m³ per day, raising the total Indian footprint to more than 230,000 m³ per day of industrial wastewater treatment.
Context: Water Scarcity and ZLD Adoption in India
India accounts for about 18 % of the global population but holds only 4 % of the world’s freshwater resources. Government projections indicate that water demand could exceed available supply by a factor of two by 2030. In response, industrial operators are increasingly turning to reverse osmosis and ZLD systems to meet stricter discharge limits and to secure water reuse. ZLD eliminates liquid waste but is energy‑intensive; Energy Recovery’s devices are positioned as a way to lower that energy burden, a point highlighted by Vice President of Wastewater David Kim‑Hak.
Market Signal: Energy Economics Driving Design Choices
Kim‑Hak noted that “operators across these industries are now designing energy recovery devices into their systems from the start,” reflecting a shift where energy cost volatility is influencing equipment selection. By integrating PX technology early, customers aim to reduce operating expenses, emissions, and exposure to fluctuating power prices. The new contracts suggest that the Indian market is responding to both regulatory pressure and the economics of energy‑intensive water treatment.
Key Takeaways
- Energy Recovery announced five new Indian wastewater contracts covering textile, photovoltaic, steel, and petrochemical sectors.
- The projects add 30,000 m³ per day of ZLD capacity, bringing the company’s total Indian support to over 230,000 m³ per day.
- PX pressure exchangers operate at up to 99 % efficiency, helping customers lower electricity use and mitigate power‑price risk.
EnergyInsyte's Take
The contracts illustrate that Indian industrial water managers are prioritizing energy‑efficient ZLD designs amid tighter discharge rules and rising water scarcity. While the orders confirm demand for PX technology, the extent to which reduced power consumption translates into measurable cost savings will depend on local electricity tariffs and plant‑level integration practices. Executives should monitor how quickly similar energy‑recovery solutions are adopted in other high‑water‑use sectors.
