TDL Energie GmbH

TDL Energie GmbH, headquartered in Neumünster, Germany, has over 30 years of experience designing, manufacturing, and operating water and gas treatment plants. The company delivers full-lifecycle projects—from conception and fabrication through installation, commissioning, and ongoing operation—serving landfill leachate, industrial wastewater, PFAS-contaminated water, digestate, and municipal wastewater sectors. Their water treatment portfolio centers on membrane technology: reverse osmosis plants, nanofiltration systems, microfiltration and ultrafiltration units, and membrane bioreactors (MBR) that combine biological treatment with membrane separation. Activated carbon adsorption systems target dissolved contaminants, while ion exchange units provide polishing for RO permeates, particularly in landfill leachate applications. TDL Energie also addresses the emerging PFAS treatment market with dedicated processing systems. On the gas side, the company builds landfill gas utilization and disposal plants, gas compressor stations, low-calorific gas flares, and high-temperature flares. All systems are manufactured at their Neumünster production facility and are available in containerized (mobile) or skid-mounted configurations for indoor installation. A fleet of mobile pilot plants allows on-site process testing, and rental RO units are available at short notice. TDL Energie has delivered installations across Germany, Europe, Russia, North Africa, and South America.
