In an effort to test the Effect of Flotation Cell Size in Laboratory, I ended up with a test for the effect of flotation density on grade and recovery. Therefore, I here present is a Laboratory experiment that counters the reality of a full scale industrial flotation plant. By counters the reality I mean, larger commercial Read more

Failure Analysis of a Dissolved Air Flotation Treatment

Jan 11, 2011 Environmental pollution in Nigeria presents an urgent need to assess wastewater treatment facilities in various industries. This article presents an assessment of dissolved air flotation (DAF) operation in a dairy industry. The industry was visited, wastewater treatment facilities were assessed (based only on efficacy to remove selected environmental health-related pollutants) and

Coal-clay slurry was supplied to the FTU from either the flotation circuit of the preparation plant or from the thickener underflow. The slurry flowed to a hold

How to Treat Waste in Bakery Industry Waste Management

The pH and coagulant dosage are important in the treatment results. Liu and Lien reported that 90-100 mg/l of alum and ferric chloride were used to treat waste-water from a bakery that produced bread, cake and other desserts. The wastewater had pH of 4.5, SS of 240 mg/l and COD of 1307 mg/l.
