Treatment of Pulp and Paper Mill Wastewater with Various
Flocculation studies between dual polymers on pulp and paper mill wastewater are reported in this paper. The effects of different molecular weights of polyDADMAC and different dosages of Polyacrylamide (PAM) were studied. The molecular weights of polyDADMAC used were 8.8×104, 10.5×104 and 15.7×104 g/mol. The flocculation performance was analyzed in jar tests with PolyDADMAC and

Treatment of Pulp and Paper Mill Wastewater with Various
Pulp and paper mill wastewater was collected from the wastewater treatment plant equalization tank of a paper mill in Penang, Malaysia, in accordance with ASTM E 300-03. This factory produces about 3000 metric tons of tissue paper a month and produces 96 m. 3 . of wastewater per ton of paper produced. The characteristics of the
Abstract The flocculation performances of different molecular weight of polydiallyldimethylammonium chloride (polyDADMAC) in the treatment of pulp and paper mill wastewater were studied. The molecular weights used were 8.5 × 10 4 , 8.8 × 10 4 , 10.5 × 10 4 and 15.7 × 10 4 g/mol. The flocculation performance test was carried out in jar tests with polyDADMAC dosages ranging from 0.4 to 2.0
Treatment of pulp and paper mill wastewater—a review
Pulp and paper mills generate varieties of pollutants depending upon the type of the pulping process. This paper is the state of the art review of treatability of the pulp and paper mill wastewater and performance of available treatment processes. A comparison of all treatment processes is presented.
Wastewater used in this study was obtained from two-step (anaerobic–aerobic) biological wastewater treatment plant effluent of a pulp and paper manufacturing company located in Tekirdag, Turkey. Composition of the pulp and paper mill wastewater used in this study is presented in Table 1.

- Why is poly(acrylamide) a good soluble polymer?
- The thermal stability of poly (acrylamide) solutions are generally higher than most other water-soluble polymers; however, the high molecular weight species, like their POE equivalents, have very high extensional viscosities, favor-able for good drag reduction behavior, but this also reflects on their rapid degradation under mechanical deformation.
- What is the standard state of polyacrylamide?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
- Is linear polyacrylamide water soluble?
- Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels.
- Is polyacrylamide contaminated with acrylamide?
- Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
