Our biological purification plants are based on the activated sludge principle, one of the most versatile wastewater treatment technologies. Since 1980, we have leveraged our experience to design plants that balance installation and operating costs while ensuring high-quality results. First, raw sewage undergoes preliminary screening, grit removal, and primary sedimentation. Then, during the biological oxidative phase, microorganisms form sludge flocs that capture remaining solids and treat soluble compounds. Finally, the secondary sedimentation separates purified effluent from sludge, which can undergo tertiary treatment with sand filters, activated carbon, or MBR membranes, delivering efficient and reliable wastewater purification.

AEROBICS
Supply of turnkey plant including building and carpentry works. Equalization tank equipped with horizontal immersion mixers and level control in order to homogenize the flow and make it possible to manage the level according to the weekly production volumes. Two lines in parallel composed of anoxic and aerobic sections with dispersed mass, nitrification and denitrification. Final clarification section with purified water that is sent directly to the drain. The sludge is thickened in a vertical conical tank and the sludge is dewatered in a screw press. The system guarantees compliance with the limits for the ongoing discharge of surface water for all parameters.

AEROBICS
Supply and installation of a turnkey plant for the oxidation of waste water from fabric bleaching. The wastewater treatment system involved simple mixing using submersible mixers, but laboratory tests had shown a reduction in the concentration of surfactants after vigorous aeration. The system now guarantees compliance with unloading limits with large margins.
