Problem: The City of Becker, Minnesota, needed to upgrade its dewatering equipment to increase treatment capacity. A limited budget prevented building expansion or conveyor replacements. High humidity in the dewatering building was exerting pressure on the electrical equipment.

Solution: The city chose the Fournier Rotary Press, known for its small footprint and flexible output configurations. The presses were pre-assembled and skid-mounted at the factory, enabling installation without rebuilding the existing concrete floor. New conveyors that receive cake from the presses seamlessly integrated with the existing conveyor system.

Result: “Our staff has been extremely pleased with the high quality of the biosolids, the ease of operation, and the quietness of the equipment,” says Dave Pesola, water and wastewater department supervisor. “The significant reduction in water usage has been an added benefit. We have decreased moisture levels in the press room that had contributed to issues with the electrical and HVAC equipment.” 418-423-4241;
