Research on water level and balanced water supply

No water, no agriculture. Therefore, a good water level and a balanced water supply are vital. Unfortunately, the freshwater supply is shrinking due to, among other things, a rising sea level. Salinization causes damage to agriculture. Additionally, the remaining fresh water often contains an excess of nitrogen and phosphorus due to fertilizers entering the soil and water.

International challenge of water scarcity

The problems in the agricultural sector extend beyond our borders. Countries with water scarcity face not only extreme drought but also salinization of groundwater in coastal areas. There is a need for methods to store water underground after periods of heavy rain and to recycle used water.

Solutions

With various desalination techniques, we can treat saline groundwater in coastal areas. Another solution is the implementation of a closed water system within greenhouse horticulture. Technologies that make this possible are an important export product to areas with water shortages. By (biologically) recovering metals, sulfur, phosphates, and selenium, the water cycle can be closed through the reuse of purified wastewater for irrigation. Any nutrients such as ammonium nitrate or struvite can be reused as fertilizers in agriculture. Another (partial) solution is the installation of sensors that monitor the soil's moisture condition. This allows farmers to adjust their irrigation and use water more efficiently.

WAC

The WAC offers and manages membrane installations. With these, you can research new membrane modules and the more efficient filtration of salts. The WAC also provides installations for biological degradation and recovery processes.
