Internally Fed Rotary Drum Thickener Aids Sludge Dewatering .

Jul 14, 2017 . JWC has designed the Monster Drum Thickener to require a short dwell time in the flocculation tank to achieve the required floc structure. The outcome is that the unit will use less polymer and require a smaller tank compared to other rotary drum sludge dewatering equipment, which translates to lower.

Polymer Flocculants Tramfloc, Inc.

They can be either anionic (negatively charged), nonionic (no charge), or cationic (positively charged). Flocculants are used to bridge the neutralized or coagulated particles into larger agglomerates, resulting in more efficient settling. Flocculants are used in solids thickening, sludge dewatering, and as coagulation aids.

LACSD Website Solids Processing

Cationic polymer is used as a flocculation aid in the dewatering of digested primary sludge, waste activated sludge, and thickened centrate. The resulting combination of polymer and sludge forms larger flocs that are easier to dewater using centrifugation. Cationic polymer is also used for thickening waste activated sludge.

Flocculant Chemical Metering Best Chemical Metering Pumps .

Feb 12, 2018 . Flocculants are polymers that promote flocculation by formation of links between themselves and thus enable suspended particles to aggregate. When the suspended particles are flocculated into larger ones, they are settled in devices like thickeners and clarifiers and removed with the underflow.
