About
WD Klärtechnik GmbH, headquartered in Rheine with a second production facility in Dessau-Roßlau, Germany, is an engineering and manufacturing company specializing in machinery and equipment for wastewater treatment plants. Founded by managing directors Markus Wersching and Matthias Domschke, the company holds ISO 9001 and EN 1090 certifications and provides end-to-end solutions from development through manufacturing to service and maintenance. WD Klärtechnik's core product lines cover the full spectrum of clarification equipment: Rundräumer (circular scrapers) in full-bridge and half-bridge configurations including Schildräumer (shield scrapers) and Saugräumer (suction scrapers); Längsräumer (longitudinal scrapers) for rectangular tanks including shield, suction, underflow (Unterflurräumer), and coke gravel (Koksgrusräumer) variants; and Sandfangräumer (grit scrapers) for grit chamber applications. The Anlagen- und Rohrleitungsbau (plant and piping) division delivers Ablaufsysteme (effluent systems) with overflow channels and weirs, Einströmsysteme (inflow systems) with immersion cylinders and baffle plates, and Belüftung (aeration systems) including blower stations and coarse-bubble aerators. The Metallbau (metal construction) division fabricates covers, walkways, railings, and platforms from stainless steel, galvanized steel, or aluminum. The Elektrotechnik (electrical engineering) team handles complete planning, design, manufacturing, and service for plant control and automation. The company maintains 24-hour spare parts availability for in-stock items and offers three maintenance service packages with emergency weekend and holiday support. Reference installations span municipal plants across Germany including Arnsberg, Sinsheim, Florstadt, Coburg, and Versmold.
