Project Background

Allgro is an agro-food company in Belgium that uses 130 m³ fresh drinking water a day in their vegetable processing and packaging installations. By installing a Membrane Bioreactor (MBR) as a biological system, followed by a full-scale reverse osmosis membrane system, the water cycle is almost closed. Membrane technology enables Allgro to reuse their process water, which significantly reduces the water footprint and the water cost.

The use of IPC^® membranes in the MBR installation enables the original equipment manufacturer to design a very compact system with a high capacity per footprint. The nature of these fully back-washable IPC^®-membranes combines a high operational flux with a low specific energy consumption, which is fully in line with the sustainable water treatment solution needs for the end-user.

In this particular installation, the use of MBR as a direct biological pretreatment upstream of a full-scale reverse osmosis installation enables 70% of their process water to be recycled.
