Energy Recovery designs and sells energy-recovery technologies for industrial fluid systems. Its products, including the PX Pressure Exchanger, Ultra PX, IsoBoost, and VorTeq, capture and reuse energy from high-pressure fluid streams to lower overall energy use and operating costs. The company serves multiple sectors such as desalination, industrial wastewater treatment, hydraulic fracturing, sour gas processing, and CO2 refrigeration, and it also offers licensing and long-term service agreements. What sets the company apart is its long history of deploying pressure-exchange technology and its portfolio of proprietary solutions that span different industries, not just desalination. The goal is to help customers reduce energy costs and environmental impact while delivering reliable, scalable energy-recovery solutions through direct sales, licensing, and services.

Energy Recovery Devices for water treatment facilities "DeROs-E(R)" receives Minister of Economy, Trade and Industry Award at the Energy Conservation Grand Prize

Energy Recovery Devices for water treatment facilities "deros-e(r)" receives Minister of Economy, Trade and Industry Award at the Energy Conservation grand prize. Its Energy Recovery Devices(ERD) for water treatment facilities, " DeROs- [E(R),] " has won the top award, the Minister of Economy, Trade and Industry Award, in the Electricity Demand Optimization category of the Products and Business Models category of the 2025 (Reiwa 7) Energy Conservation Awards (sponsored by the Energy Conservation Center, Japan). The award ceremony is scheduled to be held at Tokyo Big Sight on Wednesday, January 28, 2026. The Energy Conservation Award is a system that recognizes outstanding energy conservation efforts and advanced, highly efficient energy-saving products in Japan's industrial, business and transportation sectors. The award-winning " DeROs- [E(R)" is an energy-saving device that can reduce the equipment's power consumption and greenhouse gas emissions by highly efficiently recovering and reusing the pressure energy of wastewater generated during the water treatment process in water treatment facilities such as those used to produce ultrapure water and for wastewater and sewage treatment. A challenge with conventional ERDs for seawater desalination is that energy recovery from wastewater discharged from low-pressure reverse osmosis (RO) membranes is uneconomical. " DeROs- [E(R)" was awarded this prize in recognition of its ability to recover energy highly efficiently even under low-pressure conditions of RO wastewater pressure of 0.2 to 4 MPa by optimizing the shape of the flow path. Based on its purpose of "Enriching Lives and Shaping a Better Future Through Water and Air," Dmw Corporation will continue to create solutions that help resolve Social Responsibility issues and contribute to the development of a sustainable Social Responsibility.
