WATER TREATMENT

摘要

PURPOSE:To provide the method for the water treatment which efficiently treats low-turbidity water and can decrease the amt. of the flocculating agent to be used in the case of execution of turbidity removal of the low-turbidity water in biocontact filtration. CONSTITUTION:After the turbidity is subjected to an ozone treatment, the water is subjected to a flocculation treatment and is directly filtered without executing settlement, by which the rate of injecting the flocculating agent to the low- turbidity biocontact filtered water is decreased and the condensing and dehydrating properties of sludge in a waste water treatment are improved.
