Within the ‘Rewarding challenge’, researchers have succeeded in utilizing present applied sciences to develop some promising ideas to resolve the brine drawback. In spring 2025, a pilot will begin during which varied applied sciences can be unleashed on the bottom and drain water. The intention is to extract as a lot irrigation water as potential from groundwater and reuse drain water in substrate crops and drainage water in soil-based crops for longer. It additionally goals to recuperate vitamins and discover options for the concentrated streams (brine) that also come up when handled groundwater is used.
The three-year challenge is now midway to completion. Throughout this era, Wageningen Meals & Biobased Analysis (WFBR) and KWR have evaluated many present strategies and examined them in laboratories. In line with the researchers concerned, Marc Lanting (WFBR) and Nienke Koeman (KWR), completely different remedy ideas supply prospects. These will be utilized in varied configurations on horticultural farms, usually together with already present reverse osmosis crops. The appliance does rely upon the crop and the preliminary state of affairs, as the standard of groundwater can range enormously from space to space.
Jan van Staalduinen spoke to the researchers and wrote about it on Glastuinbouw Waterproof. For groundwater demos, the challenge group is in talks with an organization in Bommelerwaard. The plan is to launch the three ideas there from spring 2025 on groundwater containing comparatively excessive ranges of iron and calcium. Some new strategies for draining (age) water are usually not but prepared for a pilot.
