Culligan announces the launch of a containerised membrane bioreactor system for treating wastewater

Culligan, the Italian-based company, has announced the launch of a containerised membrane bioreactor system for treating wastewater from different applications to make it suitable for reuse. The system will be entirely designed and built at Culligan’s headquarters in Cadriano Granarolo Emilia and will be marketed to customers around the world.

Culligan’s MBR system combines activated sludge treatment with solids-liquid separation by means of micro-porous membranes, eliminating the need for secondary clarification tanks. By eliminating the need for a clarifier and thanks to the higher sludge concentrations possible with MBR, bioreactor tank volumes can be reduced by as much as 50% versus conventional activated sludge wastewater treatment. The result is a system with a smaller footprint.

The system uses flat sheet membranes with a pore size of 0.15 μm resulting in a clear, highly purified effluent that is suitable for reuse or further treatment by other technologies such as reverse osmosis.

The systems are available in two standard models of 25 m3/day and 50 m3/day flow rates and are fully installed within standalone 20- or 40-foot containers. The MBR can be used for a variety of applications such as commercial sites including shopping malls, hotels/resorts, and sports centres; small municipal communities; food & beverage, chemical and pharmaceutical industries; treating water for reuse as irrigation in agriculture for irrigation; and relief aid and military camps.
