RETROFITTING WATER PURIFYING SYSTEM OF SETTLING TANK USING DAF MODULE

摘要

The present invention relates to an improved water purifying system for a depositing reservoir by using a dissolved air flotation module. More specifically, a dissolved air flotation unit used for a dissolved air flotation system is modulated, and the dissolved air flotation module may be simply installed in an existing depositing reservoir. Thus, although floating algae is seasonally rapidly increased, the algae may be effectively removed. Water purification may be effectively performed in ways compared to existing pressure flotation facilities. The improved water purifying system for a depositing reservoir of the present invention comprises: a depositing reservoir having a particular depth for feeding raw water; and a dissolved air flotation module installed in the depositing reservoir. The raw water of the depositing reservoir may be purified through a dissolved air flotation module.
