Water treatment & biogas production
Colsen, realised a waste- and wastewater treatment system with biogas production in Italy for it’s client Pizzoli S.p.A. Pizzoli S.p.A. is a potato processing company that mainly produces pre-cooked French fries. The new system produces renewable energy, treats wastewater for partial re-use and recovers a large part of the phosphates from the wastewater.
The foundations for this long-lasting partnership were laid during a feasibility study into the options for extending or adapting an existing treatment system. Over the course of the project, consultancy services morphed into the co-development of an optimal system with a focus on sustainability, lowering operating costs and maximising water re-use. Uniquely, Colsen achieved maximum coordination between the various processes in the factory on the one hand and the waste- and wastewater treatment with biogas production processes on the other hand.
Colsen shared its technological know-how and carried out the entire detail-engineering process. The construction phase was performed in close collaboration with the client. After overseeing the construction process, Colsen took care of the entire start-up and commissioning phase. In 2019, Colsen provided support during extensive maintenance operations to the sludge separation system of the nitrogen removal system, replacing the MBR membrane modules after years of loyal service.
