Wooden package with foam inside for sludge dewatering equipment
In the water treatment process, solid-liquid separation and its equipment are one of the key projects. DAF dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 from water.
DAF consists of flotation tank, dissolved air system, reflux pipe, dissolved air released system, skimmer (Based on customer needs, there are combined type, traveling type and chain-plate type to choose.), electric cabinet and so on.
DAF dissolved air flotation has several features as follows:
● Small footprint, lower energy consumption; easy operation and simple management
●High efficiency of dissolved air, stable treatment effects. Electro-mechanic instruments are integrally controlled
●This equipment's dissolved air efficiency reaches up to 90%. But its volume is only one fifth of the ordinary dissolved air system. Moreover, it has stronger anti-clogging capability than other DAF dissolved air flotation
●This equipment uses new type dissolved air releaser with the advantages of high releasing degree and self-cleaning functions. And the average particle size of micro bubbles is about 15~30 μm
●This equipment uses chain-plate-type skimmer with advantages of stable operation and high efficiency of scraping
