“…The project has also started an investigation about possibilities for integrating stormwater and treated wastewater effluents through a functional landscape to polish the remaining pollution with ecological engineering principles. Besides 6 papers in scientific peer-reviewed journals: Kaczala et al, 2010;Lahoaprapanon et al, 2010Lahoaprapanon et al, 2010;Svensson et al, 2010 andKaczala et al, 2010 (under preparation), the project has produced 5 papers to international conferences (the most recent conference paper got the Best Poster Paper Award at the 5 th International Conference on Environmental Science and Technology ICEST-2010, Houston-Texas, 12-16 July, 2010, American Academy of Science-AAS) and later Henric Svensson the scholarship of Sparbanksstiftelsen Kronan for the best MSc thesis in the area. Based on the experience and the results obtained so far, it was concluded that low-cost alternative treatment options such as sorption onto dead biomass (e.g.…”

Industrial wastewater management is still neglected in a dominating part of the companies in Sweden and it is not considered as a threat to health of man and environment. The Environmental Science & Engineering Research Group (ESERG) at LNU has under financial support of KK-foundation and large/medium-size companies in Southern Sweden been studied. Even though the problem has been studied for half a century there is knowledge missing and the stormwater is still a growing problem. Every time rain falls, it washes off oils, microorganisms, litter, sediments, fertilizers, and foreign chemicals from streets, parking lots, lawns, dumpster pads, metal roofs as well from landfill, industrial and harbour sites. Industrial facilities with large impervious surfaces for different types of handling of materials are generating stormwater effluents of different qualities which vary during different time periods and same stands for process water generated of a variety of volumes and often of high pollutant concentrations. In some catchment areas, industrial and small business activities can release a significant portion of some pollutants that ends up directly into receiving waters but also at the municipal wastewater treatment plant. Small businesses and enterprises do not pay attention to routine operations and neither have they had the economic resources to implement preventive measures, treatment facilities or to employ expertise on their particular environmental issues. The project "Development of an Integrated Approach for Industrial Wastewater and Stormwater Management in the Wood-Industry Sector" has generated new knowledge about industrial waste water treatment that will be presented at the Linnaeus Ecotech 10 international conference.

“…Because of its toxicity, even in low concentrations it can kill all microorganisms. Nevertheless, formaldehyde is biodegradable in both aerobic and anaerobic systems [6]. Considering the supernatant obtained by mixing all cleaning wastewaters in the same proportion (1:1:1:1:1) after sedimentation in the large container during one week, it was found that COD, TOC and BOD 5 concentrations were reduced in average in 20%, 24% and 24% respectively.…”

In the present study, organic removal from five industrial cleaning wastewaters generated at a wood-laminate floor industry in Sweden was evaluated using a combined treatment process including sedimentation and a packed-bed column of commercial wood-based activated carbon (WAC). The supernatant obtained from the sedimentation was diluted with tap water until the COD concentration was reached 5 000 mg/L and it was continuously fed through the column by up-flow mode at a constant flow rate of 6 mL/min. The WAC performance at different bed height of 19, 38 and 57 cm was studied. The results showed that the sedimentation process removed about 20%, 24% and 24% of COD, TOC and BOD, respectively and the WAC column was effective in removing COD from the water phase. The treated wastewater volume and service time increased with the bed height increase. The column could treat 19 L of wastewater with the service time of 63.3 h and 30% breakthrough point. The experimental data fitted well with the bed depth-service time (BDTS) model. The increase of wastewater load on solid phase from 20%, 30%, 40% and 50% showed an increase of sorption capacity (N o ) and decrease of the rate constant (k).

“…Kaczala et al (Kaczala et al, 2010) constructed a biological system consisting of a lab-scale anaerobicintermittently aerated reactor. The authors achieved 65% removal of COD (Chemical Oxygen Demand) and 93% FA elimination; nitrification and denitrification processes were carried out simultaneously.…”

Adhesives are substances that increase the surface adhesion of bonded items. Unfortunately, they also emit volatile organic compounds (VOCs) which negatively impact upon human and animal health. VOCs have carcinogenic and mutagenic properties and can cause migraines, irritation to the eyes, nasal passages, mouth, and lungs, and respiratory problems. Wastewater from adhesive production is characterized by high levels of pollutants and contains high concentrations of compounds including formaldehyde that are toxic to water biocenoses. Moreover, its purification causes many problems and requires the application of specific methods. This review presents data concerning the toxicity and ecotoxicity of selected adhesives components. VOC emission rates from adhesives and wooden construction elements with adhesives are also discussed and assessed. Current knowledge on the treatment methods for wastewater containing adhesive components is reviewed. Finally, the treatment and disposal methods for solid wooden waste containing adhesives are also analyzed and discussed.
