Abstract
PURPOSE: To operate constantly a control system for filtration, by determining the number of filter ponds to be operated, matched all the time with the total filter flow rate, according to the time average flow rate of water to be treated supplied to a water purification plant and to the water levels across the filter pond.
CONSTITUTION: Water to be treated is supplied from an intake source 1 by a pump 2 to a raw water tank 3 in a water purification plant, then it is supplied to consumers through a settling tank 4, a filter pond 5, and a water cleaning bed 6 by a water distribution pump 7. The time average quantity of the water to be treated which is supplied to the water to be treated cleaning bed 6 during the operation is determined, and the levels of water across the filter pond 5 are determined, then the number of filter ponds 5 to be used is determined according to the time average water quantity and the water levels.
