Zink in recirculerende teeltsystemen : Toepassing van een ‘selectief’ zinkmembraan
In closed cultivation systems, elements will increase in concentration if more is added to the water than can be taken up by the crop. Zinc dissolves in some cultivation systems in drain water and can potentially cause crop damage (mainly by lack of iron). In this project a ‘selective’ zinc membrane is applied in the cultivation of dendrobium, that stopped dissolved zinc from passing to the clean drain tank, without emission of water. This creates a situation in which more drain water can be recirculated, so that emission of drain water by increased zinc can be prevented. No solution was found to remove zinc selectively enough from the water the be discharged.
