Abstract Closing of the water cycle is required in the forcing of tulips. For growers it is important to know if and how they can eliminate pathogens at an adequate way and which equipment is most suitable to break down plant protection products from waste water. Now participating growers have various equipment for full or partly disinfection. It is recommended to start with good pre-filtration methods to eliminate pathogens which can be fully achieved with UV and ozone, while products such as hydrogen peroxide with additives or chlorite products can be used for an after-effect in the pipe work. Phenolic compounds, released by the roots, can be eliminated with oxidising methods. However efficacy has not been investigated. Purification of discharge water, before entering the waste ditch, will be obliged. New, certified, equipment will come on the market soon. Reuse of discharge water, after pre-fi ltration and disinfection, is also an option.
