The treatment of pulp and paper mill effluent: a review
The raw wastewaters from paper and board mills can be potentially very polluting. Indeed, a recent survey within the UK industry has found that their chemical oxygen demands can be as high as 11 000 mg/l. This paper reviews the processes involved in paper making and examines the effects which they could have on the environment.

Pulp Mill Wastewater: Characteristics and Treatment
Sixty to seventy-five per cent of all the biological effluent treatment plants within the pulp and paper industry use this kind of treatment system. This chapter reviews the current pulping...
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
Pokhrel, D. and Viraraghavan,T., “Treatment of pulp
Effect of various parameters such as current density, pH, NaCl concentration and treatment time on the removal of COD from synthetic wastewater has been investigated to determine the most suitable process conditions for maximum removal of COD (lignin).
Secondary treatment of pulp and paper mill wastewaters for biochemical oxygen demand (BOD) removal worldwide has traditionally been accomplished, and particularly in North America, by aerobic treatment processes, including aerated stabilization basin and activated sludge.
Wastewater Treatment and Reclamation: A Review of Pulp
Wastewater Treatment and Reclamation: A Review of Pulp and Paper Industry Practices and Opportunities The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters.
using microbial activity [31]. After treatment, the water samples are tested in a laboratory to meet e uent permit regulations. 3. Major Properties of Pulp and Paper Mill Fly Ash A better knowledge of the physicochemical, mineralogical, and leachate characteristics of PPFA and value-added geomaterials is essential for their eco-e cient utilization.
Wastewater treatment in the pulp-and-paper industry
Wastewater treatment in the pulp-and-paper industry: A review of treatment processes and the associated greenhouse gas emission
Pulp and paper industries face serious environmental challenges, especially with regard to the conservation of water resources. Chemical thermal mechanical pulping (CTMP) is a process of pulping that combines chemical and mechanical pulping. This reduces the volume of water used in the process. But on the other hand, CTMP generates an effluent with high concentration of organic matter and is
- Can nonionic polyacrylamide be used as a gel fracturing fluid?
- Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
- What are the different types of polyacrylamide adsorption polarities?
- Specifically, it can be divided into non-ionic polyacrylamide (NPAM), anionic polyacrylamide (APAM), and cationic polyacrylamide (CPAM). C 3 H 7 ON, C 3 H 6 O 2, and C 5 H 9 O 2 N + are the basic structural units of these PAM, resulting in different adsorption polarities [ 12, 13 ].
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Is polyacrylamide a water soluble polymer?
- Polyacrylamide (PAM) is a linear water-soluble polymer with high molecular weight [ 7 ]. It has been widely used as a flocculant in industrial wastewater to aid solid–liquid separation [ 8, 9 ].
