WATER TREATMENT METHOD AND APPARATUS

摘要

A method of manufacturing a water treatment apparatus having one or more chambers comprising the step of: filling at least one chamber with ion exchanger resin; wherein at least one ion exchanger resin is dry. Preferably, the dry ion exchange resin has a water content of 0-40 wt %, preferably 0-20 wt %, and more preferably 0-10 wt %, such that the volume of the dry ion exchange resin is 25-50 vol % less than the volume of the same ion exchange resin in a moist or wetted form. One form of suitable water treatment apparatus is an EDI apparatus comprising a plurality of chambers to form a stack, for the purification of the water. The present invention provides an easier method of filling of chambers compared with the use of wetted or moist resins, and 'over filling' of the cells of water treatment apparatus.
