Polymer Dosage Control in Dissolved Air Flotation . Polymer Dosage Control in Dissolved Air Flotation It was found that below a polymer dose of about 4 mg/g of dry solids for the batch unit there was no improvement in the thickening performance (or float solids concentration) that no residual polymer could be detected in the effluent and that there was no effect on the negative Zeta get price

Sludge Thickening an overview ScienceDirect Topics

The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of

UPGRADED THICKENER OPTIMIZER BECOMES A DAILY TOOL

with a polymer dosage, the material did not settle properly, resulting in a burst of solids to the overflow. Because the overflow was re-circulated backwards in the process as flotation spray water, the flotation performance was also disrupted by the solids covered with polymers. Implementation When the thickener controller implementation

CHAPTER 3 SLUDGE THICKENING Marmara Üniversitesi

The gas formed will cause the flotation of the solids in the thickener. Chemicals like chlorine (CI 2) need to be added to inhibit the biological activity. A well operated thickener will have a solids recovery of about 95% [3]. Design of Thickeners The thickening process takes place in a settling tank with long-enough solids retention time.
