wastewater treatment - primary treatment | britannica

The activated sludge treatment system consists of an aeration tank followed by a secondary clarifier. Settled sewage, mixed with fresh sludge that is recirculated from the secondary clarifier, is introduced into the aeration tank. Compressed air is then injected into the mixture through porous diffusers located at the bottom of the tank. As it bubbles to the surface, the diffused air provides oxygen and a rapid …

fluorspar beneficiation process plant

Actual flotation conditions and equipment requirements should always be determined by having a comprehensive test made on the ore before proceeding with any fluorspar operation. Fluorspar ores may be quite complex, particularly when associated with lead and zinc sulphides, barite, calcite, iron oxide, and siliceous impurities. For this reason, a laboratory flotation test should be the first step in establishing a …

what is dissolved air flotation or daf? toro equipment

Dissolved air flotation is based on a physico-chemical process which separates solid and liquid particles by the addition of very small air bubbles. These bubbles stick on solid particles and give them a high rate of ascent. Once in the surface, the solids -the sludge- are pulled mechanically to the hopper. Dissolved air flotation gives a rate
