The primary objective of the project is to explore the technological potential of an innovative filtration technique using IOCS granulate within the agri-food sector. Developed by Hellowater, this technique functions as a phosphate-polishing step. When combined with Hellowater's reed bed filters, it creates a green-grey filtration system that combines natural and engineered solutions.  

Agro&Blauw is a cooperative development project in which companies from different sectors join forces to achieve a shared goal. The partnership includes next to UGent VEG-i-TEC water purification experts Hellowater and Akwadok, and agri-food companies Frachibel, WFT Wolfcarius Quality Fruit, and Vanderhaegen Potatoes.  
The project aims to expand the application of this technique across the sector, regardless of whether the treated water is intended for reuse, which is critical in this water-intensive industry.  

To achieve this, data will be collected from the three agri-food companies (Frachibel, WFT Wolfcarius and Vanderhagen Potatoes) to develop and validate a predictive model for filter specifications. Given the significant variation in water characteristics, such as flow rates and concentrations, across the sector, designing a pressure filter solution that suits every specific case is particularly challenging.  

Agro&Blauw is expected to deliver measurable environmental benefits. By treating wastewater and promoting water reuse, the project will reduce the consumption of drinking water and groundwater, enhance water availability for irrigation and food processing, such as the washing of food products, and improve hygiene in the food industry, ultimately reducing food loss and mitigating risks to human health.
