Product Information
- Name : Dissolved Air Flotation Machine | Wastewater Solid Liquid Separation Equipment
- SKU : BLT-290
- Category : dissolved-air-flotation
Dissolved air flotation machine is a water treatment equipment. Its dissolved air system generates a large number of micro bubbles in water. Highly dispersed micro bubbles attach to suspended particles, reducing particle density below water. The particles float to the surface by buoyancy to achieve solid-liquid separation. It includes high-efficiency shallow air flotation machine, cavitation air flotation machine and horizontal flow air flotation machine. Widely applied in raw water, industrial wastewater and municipal sewage treatment. This solid-liquid separation equipment features low investment, small footprint, high automation and simple operation & maintenance.

Working Principle
The dissolved air system dissolves air into water under pressure. After pressure release, massive tiny bubbles are produced. Bubbles adsorb suspended solids, oil and colloidal pollutants in sewage and carry them upward to form scum. The scum is scraped and collected by the slag scraper, while clean water flows out from the bottom. It realizes fast solid-liquid separation, reduces suspended solids and oil content in wastewater. As a pre-treatment unit, it effectively cuts the load of subsequent biochemical treatment.
Application Fields
Oil refining & chemical industry: Oil and suspended solids removal for oily wastewater and chemical process wastewater.
Brewing & vegetable oil refining industry: Separation of grease and suspended impurities for food processing wastewater.
Slaughter, electroplating & printing and dyeing industry: Pre-treatment of colloid and suspended solids in various industrial wastewater.
Municipal sewage: Pre-treatment of urban domestic sewage to remove floating oil and suspended solids.
