Abstract

Προς απομάκρυνση π.χ. νιτρικών από ύδωρ μ' ένα σύντομο χρόνο επαφής, το ύδωρ αναμειγνύεται με μικρά τεμαχίδια ιοντοεναλλακτικής ρητίνης εντος ενός δοχείου 1, δια να σχηματισθεί ένα εναιώρημα με περιεκτικότητα 1,25% έως 5% βάρος/βάρος. Το μέγεθος διαστάσεως τεμαχιδίων είναι πχ. από 5μμ έως 0,5 χλστμ. Το εναιώρημα διέρχεται μέσω του δοχείου 1, σε μια μονάδα διηθήσεως διασταυρούμενης ροής 3 όπου διηθείται το κατηργασμένο ύδωρ εις το 4. Κατά τη διάρκεια του χρόνου επαφής εντός του δοχείου 1 και εντός της σωληνώσεως η περιεκτικότης νιτρικών του ύδατος ελαττώνεται σημαντικά. Η ιοντοεναλλακτική ρητίνη επανέρχεται στο δοχείο 1 και μπορεί να ανακυκλωθεί κατά μέσο όρο περίπου 4 φορές. Αφαιρείται ένα ρεύμα εναιωρήματος από το δοχείο 1, αναγεννάται και ανακυκλώνεται εις το δοχείο 1.π.ωFor removal e.g. of nitrates from water with a short contact time, the water is mixed with small particles of ion exchange resin in a container 1, to form a suspension with a content of 1.25% to 5% w/w. The particle size is, for example, from 5 µm to 0.5 mm. The suspension passes through vessel 1, to a cross-flow filtration unit 3 where the treated water is filtered in 4. During the contact time within vessel 1 and within the piping the nitrate content of the water is significantly reduced. The ion exchange resin is returned to vessel 1 and can be recycled an average of about 4 times. A suspension stream is removed from vessel 1, regenerated and recycled to vessel 1.p.o
