Highlights Treatment of pulp and paper mill wastewater with coagulation and aerated basin. We examine changes of organic compound in nutrient limited (N & P) aerated basins. Effective reduction of colour nm, and UV and nm, was obtained. HPSEC analysis used to quantify the treatability of the wastewater. Solid-state 13 C NMR analysis used to quantify removal of aromatic and alkyl by: pulp mill. The total quantity of coloured effluent is about to MGD. The physicochemical characteristics of coloured effluent were given in Table 1. Waste sludge (as adsorbent) The pulp and paper mill treats the coloured and organic wastewater in a ETP consisting of clarifier, settling tank and activated sludge process. The.
came from an aerated pond, treating only the bleaching effluent (aerobic sludge), while the second (S2) came from an aerated pond, treating the overall effluent from kraft pulp mill (facultative sludge). Biological assays. The aerobic biodegradability batch assays were carried out at 20 °C in mL open bottles (with mL of working. In recent years, there have been emerging concerns regarding the fate and effects of pulp and paper mill effluents on the environment. Countries throughout the world are focusing attention on the implementation of regulatory and monitoring programs. In response, industry has begun to implement a variety of process and treatment technologies designed to minimize or eliminate the potential.

Abstract. The pulp and paper industry ranks third in terms of water consumption and fifth among the major industries in its contribution to water pollution problems in the USA. Pulping, bleaching, and paper-making operations are the three major wastewater sources of the by: 3.
An earlier order-of-magnitude economic estimate for an unbleached kraft pulp and paper mill indicated that effluent treatment and reuse, based on activated carbon, produced at the mill, promises to be competitive with treatment and discharge, based on the lime treatment pioneered by the National Council for Air and Stream Improvement (NCASI) (63).
The removal of chlorinated organic compounds from bleached kraft pulp mill effluent in an operating biological treatment system, consisting of an aerated lagoon and settling pond Author: Pratima Bajpai.
this work is to evaluate genotoxicity of kraft pulp mill effluent using Bacillus subtilis “rec” assay, before and after treatment by activated sludge (AS) and aerated lagoon (AL).
Effluent sample from a local BKPM, which process Pinus radiata was used. The lack of knowledge of the bacterial communities present in the aerated lagoons of the pulp and paper effluent limits the capacity to take advantage of maximizing its purifying capacity.

Universidad Nacional de Misiones (UNaM) -Consejo Nacional de Investigaciones Científicas y Técnicas. In the present paper, a pilot-scale aerated lagoon was used for the aerobic treatment of pulp and paper mill effluent.
The lagoon treated real wastewater from a pulp and paper mill. Environmental parameters (temperature, pH, COD, and BOD 5 of influent water) were monitored daily. Detoxification of bleached kraft mill effluents J. Mueller and C. Walden Biological treatment of bleached kraft mill effluents is aimed at removal of 5-day biochemical oxygen demand (bod5) and toxicity.
The systems most commonly used by the pulp and paper industry are stabilization ponds, aerated lagoons, and activated sludge processes.1"3 The bod5.
Kraft mill effluent was treated by an aerated lagoon (AL), which was operated with three different stigmasterol load rates (SLR =and mg/L x d) and a hydraulic retention time of 1 day.
The AL’s maximum Chemical Oxygen Demand (COD) removal was 65%, whereas the Biological Oxygen Demand (BOD 5) was around 95%. Stuthridge et al.
() reported 65% removal of AOX from bleached kraft pulp and paper mill effluent. Junna and Ruonala () reported removal of BOD 7 ranging between 50% and 75% and chlorinated phenolics 10–50% by an aerated lagoon.
Achoka () reported that an oxidation pond removed chemical compounds greater than 50%.Cited by: The gas-liquid interfacial area and pH are of utmost importance. For a typical effluent with MST of hr, approximately 30 m²/l of interfacial area given to an effluent at pH > are required for detoxification.
Foam separation is universally applicable and reliable for detoxifying kraft whole mill effluent. Carlson et al. () reported on an upgrade of an aerated lagoon treating a kraft pulp mill effluent to an activated sludge configuration. After the upgrade was completed, the quality of the treated effluent, which now meets the permit requirements, was significantly improved.

Back inPulp and Paper Magazine ran a page “special report” called “Closing the Loop: The Effluent-Free Pulp and Paper Mill.” In it were a series of articles about how pulp and paper mills have “moved closer to effluent.
