Smart Loop

The Smart Loop is a very efficient solution for primary treatment of mill effluent prior to the biological effluent treatment plant. Suspended solids are removed to a very large extend from effluent streams such as U-drains, filtrates from reject and sludge dewatering, unforeseen overflows or accidental spills to the sewer from all over the mill. The cascade of ELEPHANT thickener and Dissolved Air Flotation handles higher solids and flow peaks compared to any other technology used for primary clarification, providing reliable clear water quality and safe operation conditions of the subsequent effluent treatment plant. Thickened solids from the ELEPHANT can be sent directly to a sludge press or if suitable be kept for the production. Clarified water from the DAF can be sent to biological effluent treatment or may be partially recirculated to the process to control the water consumption of the mill.
