Aquen Aqua-Engineering Gmbh
About
Aquen Aqua-Engineering GmbH is a technology company based in Clausthal-Zellerfeld, Germany, specializing in sludge conditioning and solid-liquid separation optimization for municipal and industrial wastewater treatment. Originally spun off from the Clausthaler Umwelttechnik-Institut GmbH (CUTEC), Aquen holds international patents on its flocculation and dewatering technology. The company's flagship product, the FlocFormer+, is a two-stage flocculation reactor that first uses a Turbo-Mischer to incorporate polymer into the sludge and create large, shear-stable flocs, then applies a modified cone stirrer to selectively erode and compact those flocs — resulting in up to 25% improvement in dewatering results and up to 30% reduction in polymer consumption and disposal costs, with an amortization period under one year. The FlocFormer+ is compatible with chamber filter presses, decanters, belt filters, and other dewatering units. The FlocStirr is a dynamic inline mixer providing effectiveness-optimized polymer dosing directly into the sludge stream for consistent floc formation. Real-time monitoring is handled by the FlocSens Pro, a photo-optical sensor that measures floc properties in process conditions for continuous dewatering control, while the FlocSens Lab provides the same optical measurement capability in a laboratory format for reproducible flocculation testing and polymer dose optimization. The FlocPhos system achieves efficient phosphate precipitation from wastewater, targeting discharge concentrations of 0.4 mg/L phosphate by reducing the beta value for precipitation chemical consumption. The geoCLEA mobile dewatering unit handles drilling cuttings and similar difficult materials. Aquen provides consulting, engineering, assembly, commissioning, and ongoing maintenance services, serving municipal wastewater treatment plants, industrial facilities with specialized separation requirements, and agricultural operations needing slurry and digestate treatment.
