Abstract
PURPOSE: To manufacture fresh water of high quality while reducing the quantity of a used flocculating agent, by taking out waste sludge accumulated on the bottom part of a sludge blancket type condensating and precipitating tank and by adding it to feed water when the turbidity of the feed water is low.
CONSTITUTION: When feed water of ≤15 in degree in turbidity is supplied to a sludge blancket type condensating and precipitating tank to manufacture fresh water, even the addition of a flocculating agent to the feed water hardly forms a flock layer. For this purpose, sludge accumulated on the bottom part of the tank is taken out partially or entirely and the turbidity of the feed water is adjusted. Then, the sludge accelerates the flocking of a new flock forming component in the feed water, so that fresh water of high quality can be obtained with a small amount of the flocculating agent.
