nrw Anlagentechnik GmbH
About
nrw Anlagentechnik GmbH is a German manufacturer based in Hückelhoven that specializes in screening systems for mechanical wastewater treatment and industrial water applications. The company was founded by Stefan Fischer, who has over 32 years of experience in screening technology dating to 1993, and the team collectively brings more than 70 years of expertise. Their flagship product, the nrw contec screen, is a single-stage screening system offering throughputs from 2.5 to 3,600 cubic meters per hour with screen openings from 0.8 mm ultra-fine to 16 mm coarse. Constructed from stainless steel 1.4301, 1.4571, or Duplex 1.4462, the contec screen uses energy-efficient gear motors operating at approximately 2 rpm and is designed for self-cleaning operation with minimal maintenance and low cleaning water requirements. The Combi Screen provides dual-stage coarse and fine screening in a single unit driven by one motor, achieving throughputs up to 80 cubic meters per hour. The River Water Screen handles up to 3,600 cubic meters per hour for river water extraction in industrial cooling and process water intake applications. The ASF 400 Screw Press dewaters screenings and high-solids wastewater up to 60 cubic meters per hour. nrw Anlagentechnik also supplies accessories including screenings presses, screenings washing presses, heating systems for winter operation, emergency overflows, exhaust piping, and custom electrical control systems. The company's screening technology is specifically engineered to protect downstream membrane systems through effective preliminary treatment. Served sectors include municipal wastewater treatment, industrial process and cooling water, the paper industry for fiber separation and dewatering, food industry for juice production and pomace dewatering, biogas plants for fermentation residue separation, recycling and environmental technology, and maritime applications. Customer testimonials reference installations at CHT Germany GmbH (Tübingen), the City of Monheim, and Klingele Paper Mills (Weener).
