Paper Mill Effluents

At present, a large amount of water required for paper production and various chemicals has been identified in effluents, which is produced at different steps of paper making in paper mills. The pulp and paper industry is typically related to pollution difficulties related to high biological oxygen demand (BOD), chemical oxygen demand (COD), colour, suspended solids, lignin and chlorinated compounds. Several studies have been made on eliminate these difficulties of pulp and paper effluents, the problem still continues. Although the physical and chemical methods are on the track of treatment, they are not on par with biological treatment because of cost ineffectiveness and residual effects. The biological treatment is known to be effective in reducing the organic load and toxic effects of paper mill effluents. Some microorganisms including bacteria and fungi have been involved in degrading the chemicals present in pulp and paper mill effluent. This article is an overview of the attempts made by several researchers worldwide to use biotechnological methods for degradation of the toxic compounds present in pulp and paper mill effluents by using fungi, bacteria, algae and enzymes. The current study clearly shows that application of native dominant bacterial and fungal isolates may be used forthe treatment of large pulp and paper mills effluents.

Qualitative And Quantitative Characteristics

AbstractThe first part of this investigation studied complex nature of chemical oxygen demand (COD ) parameter on local and overall effluents, which were obtained from two pulp and paper mills, located in the Northwest region of Russia. Contribution of individual compounds and fractions of matters having different chemical nature to COD for these effluents was established. The second part of this study shows that, qualitative and quantitative characteristics of priority pollutants and their contribution to COD for different pulp and paper mills are not the same, though these mills use similar technologies and produce similar products.

Adsorption Processes

In the present review, the suitability of adsorption process using low cost adsorbent for the treatment of pulp and paper mill effluent has been discussed. It is clear that adsorption processes are appropriate for the removal of recalcitrant compounds such as surfactants and pesticides, among others biodegradable or non-biodegradable compound present in pulp and paper mills effluents. The importance of the  adsorption is to improvement of the  removal of various physico- chemical (biological oxygen demand (BOD), chemical oxygen demand (COD), colour, suspended solids, lignin), heavy metals (Cu, Cr, Fe, Zn, Ni and Mn etc) organochlorine compounds, all recalcitrant pollutant, reduce toxicity, enhance colour removal by using different cost effective adsorbents. The effective use of the different adsorbents developed from different adsorbent media such as activated carbon, agriculture by product and industrial wastes and sludge as adsorbents  for the removal of different pollutants from the various processes and operations of pulp and paper mill as potential alternatives to different treatment process and received widespread attention. Adsorption necessity is a novel treatment option to improve the efficiency of removal within the discharge limits of wastewaters into the receiving bodies without causing any damage of the environment. However, still there is a need to find out the practical usefulness of such low cost adsorbent at industrial scale with the special reference to metals.

The results of investigations into the effects of wastewaters from pulp and paper production on the River Sava are presented in this paper. Two situations were studied, i.e., when the treatment plant was in operation and when it was not working. The results of the investigations indicated that the wastewaters had significant effects on the Sava. Chemical oxygen demand (COD) and biochemical oxygen demand (BOD) were increased and some toxic substances were present at high concentrations, e.g., phenols, oils and grease, dyestuff, etc. The negative influence of the wastewaters was greater during the summer, at low water levels in the Sava. The Sava is a tributary of the River Danube, into which the pollution from this river finally flows. Regardless of the water flow rates, toxic substances are constantly accumulating, and, as a result, even such large systems as the Danube and the Sava are becoming more and more polluted.

Rainbow Trout Oncorhynchus Mykiss

Abstract In Canada, effluents from pulp and paper mills are regulated for toxicity. The regulation requires ≥50% survival of rainbow trout (Oncorhynchus mykiss) exposed to full-strength (i.e., 100%) effluent for 96 h in tests that must be conducted monthly. The regulation also calls for ≥50% survival of Daphnia magna exposed to 100% effluent for 48 h in weekly monitoring tests. Every year, about 10 to 25% of the mills exceed the regulatory limit at least once in tests with either rainbow trout or Daphnia magna. Between 1996 and 2003, we investigated 84 such cases from 32 mills. Of the 84 investigations, 49 involved only trout, 29 involved only Daphnia, and six involved both species. We identified the actual cause of toxicity in 70% of the cases and partially or tentatively identified the toxicant(s) in 17% more. In the cases involving only trout, the most frequent causes of toxicity were related to biotreatment performance (e.g., ammonia). In the cases involving only Daphnia, the most frequent cause of toxicity seemed to be related to polymeric formulations. For those cases involving both trout and Daphnia, the cause of toxicity was traced to more than one compound or to excess concentrations of a specific compound resulting from a spill or biotreatment-related problems.

The use of coagulation and flocculation for tertiary treatment of pulp and paper mill effluent was investigated, where the evaluation was based on the removal of nitrogen (N), phosphorus (P) and BOD from post-coagulated wastewater. The study was undertaken on laboratory scale aerobic stabilisation basins (ASB). Two post coagulated (alum) wastewaters were studied, where the BOD:N:P ratios were 100:1.3:0.06 and 100:1.3:0.3. These wastewaters were treated in two identical concurrent simulations (A & B). The influent ratio for ‘A’ was selected representing the composition of actual coagulated Pinus radiata sulfite pulp effluent mixed with paper mill effluent. The input composition for ‘B’ represented a typical P concentration found in existing pulp and paper mill effluents. Unmodified sludge collected from a mill-pond was added at 4% v/v to each simulation replicating the treatment conditions at full-scale. Similar high percentage removals of BOD and COD occurred after 28 days (two HRTs) which were 94 and 67% respectively for ‘A’, and 98 and 70% respectively for ‘B’, where both remained at steady state during the third HRT. A statistical analysis of the data revealed that there was no significant difference in the sample variance of the BOD and COD results.

Hazardous Compounds

The Ministers' Declaration from the 2nd North Sea Conference recommended a goal to be set to diminish the discharge of hazardous substances via rivers by 50% over the next 10 years, e.g. to diminish the discharge of persistent halogenated compounds from pulp and paper mill effluents. The Paris Convention adopted this recommendation later. Based on a study conducted for the EEC Commission, we have arrived at the following conclusions to fulfil this goal. For historic reasons the regulation of the pulp and paper industry includes some parameters which may not be the most appropriate ones, e.g. BOD5 and AOX. To regulate the bleached pulp mills by AOX/TOC1 is not recommendable. PCDD/PDDFs are very difficult to regulate at present. Regulation of polychlorinated phenolics (PoCPs) in the effluent may prove to be a valid indirect measure of TCDD-equivalents, but this has yet to be proven. To ensure sufficient removal of hazardous compounds, we recommend that standards for TSS be stringent, as the major fraction of hazardous compounds is associated with suspended solids (including PoCPs and PCDD/PCDFs). Effluent control should be based on pH, COD (Chemical Oxygen Demand using dichromic acid), TSS (total suspended solids) and PoCPs. At present there are not sufficient data available to establish a regulation based on these parameters. So, further data should be obtained.

Practical Experiences

An industrial aerobic biofilter technology has been piloted extensively in Canada on several types of pulp and paper mill effluents, resulting in one full scale operational facility at one Canadian fine paper mill. In addition two industrial scale pilot plant tests were performed with the same technology, one in an integrated sulfite pulp and paper mill and one in a TMP mill. In the case of the fine paper mill, the full scale plant has two cells (8 m × 8 m × 6 m height of the media) and treats an unclarified but screened effluent with a loading of 3500 kg BOD/d. The system produces low quantities of biosludge (0.28 kg TSS/kg BOD removed), has a rapid rate of recovery after shock loadings and is very energy efficient (150 kW installed power for aeration). Pilot plant treatability studies were performed at one integrated Canadian sulfite mill using a combination of a biofilter-aerated lagoon system. The biofilter treated the most concentrated stream (sulfite pulp mill effluent) and this stream was then combined with the remaining wastewaters of the mill and polished in an aerated stabilization basin (ASB). The high quality ASB effluent (50 mg BOD/L/30 mg TSS/L) was non toxic to rainbow trout, Daphnia magna and photoluminescent bacteria. Integrated TMP mill effluents were treated in a 5 m3 aerobic biofilter filled with two types of media (10 to 20 mm and 20 to 30 mm). Under average loading conditions of 3.5 kg BOD/d.m3 media, the system produced effluents meeting regulation limits for BOD, TSS as well as for toxicity.

Pre Treatment

Since the early 1980s, anaerobic treatment of industrial effluents has found widespread application in the pulp and paper industry. Over 200 installations are treating a large variety of different pulp and paper mill effluents. Amongst various anaerobic systems the UASB and IC are the most applied anaerobic reactor systems. Anaerobic treatment is well feasible for effluents originated from recycle paper mills, mechanical pulping (peroxide bleached), semi-chemical pulping and sulphite and kraft evaporator condensates. The advantages of anaerobic pre-treatment are (1) net production of renewable energy (biogas), (2) minimized bio-solids production, (3) minimal footprint and (4) reduced emission of greenhouse gases. Via in-line application of anaerobic treatment in closed circuits (paper kidney technology) further savings on cost of fresh water intake and effluent discharge levies are generated.

Experimental exposure to bleached kraft pulp and paper mill effluent (BKME) at a concentration of 10% significantly reduced the abundance and mean number of species of Dactylogyrus on the gills of naturally infected roach, Rutilus rutilus, over a 3 week period. Seven Dactylogyrus species were recorded which differed widely in their susceptibility to the effluent. The experiment coincided with a natural spring peak in dactylogyrid infections on roach. BMKE exposure did not prevent parasite reproduction but post-larval abundance was significantly higher on control than effluent-exposed hosts. There was no evidence of a BKME-induced shift in microhabitat distribution of dactylogyrids. Elevated levels of infection with Dactylogyrus spp. have been recorded on roach from a Finnish lake containing relatively low concentrations of BMKE. The high exposure concentration in this experiment produced a similar reduction in dactylogyrid infections to that reported in separate studies in close proximity to Swedish pulp and paper mills. The discrepancy between the results of the Finnish and Swedish field investigations is therefore considered to be due to differences in BKME concentration between the study areas.

Paper Mills

Small-scale agro-based pulp and paper mills are characterized as highly polluting industries. These mills use Kraft pulping process for paper manufacturing due to which toxic lignified chemicals are released into the environment. Lack of infrastructure, technical manpower, and research and development facilities restricts these mills to recover these chemicals. Therefore, the chemical oxygen demand (COD) of the emanating stream is quite high. For solving the above problem, four bacteria were isolated from the premises of agro-based pulp and paper mill which were identified as species ofPseudomonas, Bacillus, Pannonibacter, andOchrobacterum. These bacteria were found capable of reducing COD up to 85%–86.5% in case of back water and 65-66% in case of back water : black liquor (60 : 40), respectively, after acclimatization under optimized conditions (pH 6.8, temperature 35°C, and shaking 200 rpm) when the wastewater was supplemented with nitrogen and phosphorus as trace elements.
