Floc properties and membrane fouling in coagulation/ultrafiltration process for the treatment of Xiaoqing River: The role of polymeric aluminum-polymer dual-coagulants.

Chemicals coagulants such as poly-aluminum chloride (PAC), essentially the same coagulants used in paper formation, can be used to assist pressing more water from sludge (Ghosh et al. 1985; Leitz 1993; Pawlowska, Proverb 1996). Side benefits of sludge dewatering may include a) more stable, solid-like sludge, b) the colloidal materials in the ...

Flocculation performance of papermaking sludge-based flocculants in different dye wastewater treatment: Comparison with commercial lignin and coagulants Feng, Qiyun Gao, Baoyu

polyacrylate per kilogram of sludge and assumin a 0.2 kg/m2 sludge application rate, soil depth of 0.2 m and soil density of 1600 kg/m 8 (950 mgkg x 0.2 …

As can be seen in Fig. 1, when the three coagulants were used separately with the PAM to treat the papermaking white water, the Al 2 (SO 4) 3 + PAM and the PAC + PAM had an equivalent effect on the sludge settling speed. The PDADMAC + PAM had a …

1. Removal of water from sludge by Cationic Flocculants for Paper Making Before the sludge is concentrated and enters the mechanical dehydration, it is necessary to add chemicals to the sludge for treatment. Due to different papermaking processes, the chemicals added are different.

Effects of coagulants on papermaking processes and paper properties. ... Firstly, activated sludge was treated with 3% acetic acid for 30 min and then placed in a beaker for 90 min at 100 °C ...

What is Coagulation and Flocculation? Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.. Coagulants. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping …

In this study, papermaking sludge-based flocculant (PSBF) and commercial lignin-based flocculant (LBF) have been synthesized by the same graft copolymerization procedures. The structures of alkaline lignin (AL), commercial lignin and the two flocculants were characterized by the modern analytical me …

Polymeric ferric sulfate is also used to sludge press mud. It will have excellent effect with used with few of polyacrylamide. Polymeric ferric sulfate (PFS) is widely used for industries wastewater treatment of printing and dyeing, paper making, electroplating, circuit board, food processing, pharmacy, fertilizer, pesticide etc.

Coagulants and Flocculants perform an important function in the operation of sediment basins. The fact sheet describes why they are needed, the coagulation and flocculation process and also provides guidance and a process for product and dosing system selection for use with sediment basins. 2. Clay and colloids

In this study, papermaking sludge-based flocculant (PSBF) and commercial lignin-based flocculant (LBF) have been synthesized by the same graft copolymerization procedures. The structures of alkaline lignin (AL), commercial lignin and the two flocculants were characterized by the modern analytical methods, also, the molecular weights and charge ...

Jan 01, 2021 · PSBF and LBF were prepared from AL and commercial lignin, respectively. The flocculants above followed the same preparation procedures. Lignin, cellulose and hemicellulose were abundant in papermaking sludge, so AL was extracted from papermaking sludge according to the acid-alkaline method: ⅰ) Papermaking sludge was added into deionized water and the …
