Recirculation of water is now a standard aspect of water management in horticulture. It avoids needless waste of expensive nutrients and water. But re-using drain water (and other water) is not without risks. The water that comes back from the greenhouse can contain unwanted micro-organisms, such as viruses, bacteria and fungi. There are various ways to remove these micro-organisms. One of these solutions is the Kathari ultrafiltration, developed by Van der Ende Group, which uses membrane technology to achieve a very high removal rate with great cost-efficiency.
