Re-using drain water in the correct way allows growers to save on expensive nutrients and water, with the additional advantage of reducing the environmental burden. Because drain water can contain pathogens,
effective treatment is essential. The Kathari gives your crops optimum protection against viruses, bacteria and fungi – with high removal certainty and low operating costs. It achieves a high Log reduction of viruses, bacteria and fungi by means of ultrafiltration (UF). And as UF is a low-energy technique and uses no antimicrobial products, it is very cost-efficient.
Advantages of the Kathari:
– Physical removal of:
– viruses (Log4)
– bacteria and fungi (Log6)
– organic pollution
– Less organic/biological pollution in the watering system
– Insensitive to water turbidity
– Very low operational/energy costs
Application UF for ToBRFV removal
The Kathari UF is an excellent filtration technique for the removal of ToBRFV. A trial, conducted by Groen Agro Control, tested the effectiveness of UF of ToBRFV-contaminated drain water. After filtering ToBRFV-contaminated drain water with a UF filter, no contamination was found in a bioassay with two times five tomato plants. Therefore, in this test no virus was detected after ultrafiltration.
