Actina™ - Pellet softening providing the users’ comfort. Actina™ is a drinking water softening process by pellet softening designed to limit calcium carbonate deposits. Actina™ is a drinking water softening process by pellet softening designed to limit calcium carbonate deposits caused by a daily use of hard water on dishes, shower systems or in the pipes. These deposits can cause clogging and affect the proper operation of household appliances and water heaters. By reducing the calcium hardness at the earliest stage possible, Actina™enables Municipalities and Industries to access softened water peacefully, and to dispense with additional softening in private property or in their factories.

Agira™ is a two-stage intense aerobic process for the treatment of grease and greasy sludge. Agira™ consists of a hydrolysis tank and an aerobic bioreactor: The hydrolysis tank pre-treats the greasy matters in presence of lime before entering the bioreactor. The aerobic tank includes a patented foam cleaner and a dynamic mixer. This configuration enhances the biomass temperature (40-50°C) allowing high elimination efficiency in a reduced reactor footprint and low energy consumption.

The Alizair™ process avoid the propagation of odors and provide the operating agents with a healthy and safe environment. In the sanitation network, the absence of air (and more precisely of oxygen) makes that wastewater become septic, and also malodorous. Gases are accumulated in the sewer headspace and emission to the open air can occur at the outlet in the treatment plant. Wastewater and its by-product treatment (sludge, scum, etc.) also generate unpleasant smells. The chemical species responsible of the olfactory nuisances are mainly Sulphide, Nitrogenous compounds and, sometimes, Volatile Organic Compounds (VOC).

Amdro™ is a patented technology for desalination of acidic wastewater with high concentrations of metals and calcium salts. Amdro™ is a patented technology for desalination of acidic wastewater with high concentrations of metals and calcium salts.The technology combines our Actiflo® high-rate clarification process with filtration, reverse osmosis and ion exchange to generate high-quality effluent with minimum pretreatment requirements. The processes ahead of the RO reduce the particulates and retain scale-forming contaminants to prevent the scaling of membranes upon concentration.The RO is operated in double-pass mode to treat the wastewater first under acidic conditions, which effectively controls scaling, and then at a neutral pH condition, to further remove dissolved inorganic compounds.

Anita™ Mox, Veolia Water Technologies anammox process, is a cost-effective and sustainable solution for the treatment of streams highly loaded in ammonia, such as municipal effluents from anaerobic sludge digestion, drying condensates, industrial wastewaters and landfill leachates. Compared to conventional nitrification-denitrification processes, the Anita Mox process achieves an ammonia removal efficiency of over 90% with no use of external carbon source and at a very low energy cost, thus making it the ideal solution to reduce operating cost and improve the environmental record of a wastewater treatment plant.
