Extensive treatment in three works combining Imhoff pit, pre-denitrification, activated sludge and recirculation.

Complete treatment by primary sedimentation and aerobic filtration with air blowing.

Station combining anaerobic percolator filter and activated sludge for advanced biological purification.

Secondary treatment by fixed biomass and air blowing, with effective degradation of organic matter.

Activated sludge plant with aerobic digestion and integrated clarification for quality final discharge.

Secondary treatment of pretreated water using biomass fixed on plastic supports with a high specific surface area.

Compact and silent micro-station with automated cycles of filling, oxidation, sedimentation and rejection.

Complete treatment by decantation, aerated fluidized bed biofiltration, clarification and automated recirculation of sludge.

Complete treatment by sequential cycles of anoxia, aeration, sedimentation and rejection.
