Abstract

PURPOSE: To prevent ion exchange resin powder from leaking after purifying, collecting and flowing of feed water, by circulating the water in repetitive cycles of the highest linear flow rate and low linear flow rate during the purification of the feed water while holding a precoating layer of the ion exchange resin.
CONSTITUTION: Water of a dilute resin slurry supplied to tank 1 circulates to precoating tank 8 through the liquid penetrating gap of precoating agent holder 2 and resin is held on holder 2. The resin slurry is supplied for about 40min to form resin precoating layer 24 on metal netting 23 and then pump 6 is actuated. The control valve 16 is opened and the amount of supplied water is increased up to 11m/h per filtration area and after this state is held for 20min, valve 16 is closed. Water collection valve 17 is opened, circulation pump 5 is actuated and flow control valve 15 is opened gradually to form the circulation line of original tank 4, circulation pump 5 and filter tank 1. When the amount of this circulation reaches an enough value to hold precoating layer 24, pump 6 is stopped.
