Combined Treatment

Wasterwater Reuse – Membrane Bioreactor (MBR)

Combined treatment consists of combining several stages of treatment in package units called membrane bioreactors (MBRs). These bioreactors incorporate activated-sludge biological treatment as well as ultrafiltration-membrane clarification to produce effluent that can be discharged into sensitive areas or re-used. Depending on the concentration of the sludge in the tank and the envisaged treatment capacity, several solutions may be introduced:

• a structure incorporating one or more Ultragreen for facilities handling up to 100,000 PE and a sludge concentration of 15 g/l,

• a structure incorporating one or more Ultrafor that accept sludge concentrations of 10 g/l, with no limit to unit size,

• the installation of for a maximum capacity of 450 m3/day per unit,

• the installation of for a maximum capacity of 1,750 m3/day per unit.
