  • Can polyacrylamide and tanfloc be used in dairy wastewater flotation?
  • Polyacrylamide and tanfloc were used in dairy wastewater flotation. Coagulant dosage and pH were statistically optimized. Optimum point was 758.3 mg L −1 of PAM with 205.4 mg L −1 of tanfloc at pH 7.6. Expressive reductions in pollutants were achieved for treatment of dairy wastewater.
  • Can dissolved air flotation improve dairy effluent treatment conditions?
  • Expressive reductions in pollutants were achieved for treatment of dairy wastewater. The objective of this work was to optimize the conditions of dairy effluent treatment by dissolved air flotation (DAF) at the chemically assisted primary treatment level using the combined polyacrylamide (PAM) and Tanfloc coagulants.
  • What is dissolved air flotation (DAF)?
  • Dissolved air flotation (DAF) has gained widespread usage over the last forty years for the removal of suspended solids (TSS), oils and greases (O&G), and biochemical oxygen demand (BOD) from wastewater and other industrial process streams.
  • What is the difference between dissolved air flotation (DAF) and secondary flotation clarification?
  • Both treatment steps adopt the dissolved air flotation (DAF) principle to float solids and impurities out of the wastewater. However, the secondary flotation clarification step employs dual media filtration after flotation. Chemical coagulants and flocculants were added to enhance particle formation for rapid removal by physical means.
