DeFraWater GmbH
About
DeFraWater GmbH, based in Seevetal-Hittfeld, Germany, has spent over 25 years engineering membrane-based water treatment systems for marine, industrial, and municipal applications. The company holds TÜV ISO 9001:2015 certification and qualification under the German Water Management Act. DeFraWater's core technology is its proprietary open-channel membrane module, which enables high-efficiency ultrafiltration and reverse osmosis in compact, skid-mounted configurations. The company's signature offering, the UF+RO Fresh Water Unit, combines both membrane stages into a single fully automatic system producing potable and technical-grade water from seawater, primarily for offshore vessels and platforms. On land, DeFraWater designs and builds landfill leachate treatment plants that use RO membranes to strip heavy metals, dissolved salts, and high organic loads from contaminated seepage, producing effluent that meets regulatory discharge standards. Industrial customers rely on DeFraWater's process water desalination systems to deliver salt-free water for drilling, milling, and emulsion cooling in metallurgic operations. Additional product lines include contaminated water cleaning systems for regulated industrial discharge, potable water quality improvement systems that remove fertilizer residues, heavy metals, medical waste, and antibiotics down to the molecular level, as well as grease trap systems and chemical dosing packages. Every plant ships with full automation, allowing unattended operation. DeFraWater has delivered and serviced over 123 treatment systems for more than 85 customers across 15 countries, underscoring its focus on repeatable, containerized solutions that can be deployed and maintained internationally.
