Product Description
The wastewater DAF unit is one of the most important projects for solid and liquid separation, and it is also the most effective way to remove tiny suspended particles with a specific gravity close to water. The equipment is widely used in water supply and drainage projects.
Product composition
The wastewater DAF unit is composed of an air flotation tank, a dissolved air system, a dissolved air return pipe, a dissolved air discharge device, and a slag scraping device (combined, truss or chain plate type can be selected according to application requirements). ) and electrical cabinets.
Working principle
The wastewater DAF unit is a separator that obtains clean water by separating suspended solids, fats, oils and greases from water. A large number of micro-bubbles generated by the dissolving and releasing system are attached to solid or liquid particles with the same density as wastewater, so that the whole floats to the surface, so as to achieve the purpose of solid-liquid or liquid-liquid separation.
Advantage
1) High gas-liquid dissolution efficiency, low-pressure operation, dissolved gas-water dissolution efficiency of 80-100%
2) Large capacity, high efficiency and small footprint.
3) Compact structure, convenient operation and maintenance.
4) Sludge expansion is eliminated.
5) The air floats into the water to inflate, which has obvious effect on removing the active agent and odor in the water. At the same time, the increase of dissolved oxygen provides favorable conditions for subsequent processes.
6) When dealing with water with lower temperature, lower turbidity and more algae, this method can achieve the best results.
