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.

Many recent studies have shown processes or models to minimize the energy consumption on a municipal wastewater treatment plant (WWTP) in operation. Today the main drivers are the energy and CO2 reduction. On existing plants, the potential success of achieving the Energy neutral WWTP depends on the effluent guarantees demanded and the eventual additional carbon sources on the digesters. Veolia has now developed a tool to estimate the energy consumption and the CO2 impact to select the appropriate treatment lines (water and sludge) up front at the project stage. The real challenge is to cover the needs of the plant without external carbon sources added to the digester. At the project stage, before the bid of the WWTP, due to time constraints only few comparisons can be performed to predict the energy consumption and CO2 impact and provide the best solution to reach to the energy neutral plant as electricity wise. One conclusion of the study is that, the raw water characteristics and the effluent guarantee has a great impact on the possibilities to reach the target. Furthermore, working on reducing the power consumption and on increasing the biogas production for example by a continuous Thermal hydrolysis is a good way to go towards self sufficiency.

Abstract One of the basic threats in terms of concrete used for tanks or ducts applied in wastewater management is the phenomenon of biogenic sulphate corrosion (BSC). BSC is a particular case of corrosion caused by the action of sulphuric acid (IV), which is formed as a result of a number of biochemical processes, which can take place, e.g. in an environment encountered within the aforementioned structures. Ions present in sulphuric acid react with cement hydration products, which leads to replacing the primary cement matrix components with compounds easily-soluble or highly-swelling during crystallization. The outcome of advanced corrosion is usually an observed formation of a white, amorphous, sponge-like mass, which is easily separated from the underlying concrete. The article discusses a case study of a BSC process in a newly constructed primary settling tank in a municipal wastewater treatment plant.

A waste water treatment plant (WWTP) adopts sequencing batch reactor (SBR) process, which exist the problem of instable treatment effect on denitrification and dephosphorization. The total nitrogen (TN) and total phosphorus (TP) of the effluent could not reach the class A standard of discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002) (hereinafter referred to as the class A standard) as a result of different order in utilizing the carbon source between nitrification and denitrification. The step-feed procedure is used to improve the efficiency of denitrification and dephosphorization. Field experiments about the effects of the different influent distribution ratio (marked as λ) on denitrification and dephosphorization were carried out and the results showed that the effect of the effluent TN is the best and other indexes could also achieve class A standard when λ is 5:3.

Abstract Constructed wetlands are characterized by specific conditions enabling simultaneous various physical and biochemical processes. This is the result of specific environment for the growth of microorganisms and hydrophytes (aquatic and semiaquatic plants) which are capable of living in aerobic, anaerobic and facultative anaerobic conditions. Their interaction contributes to the intensification of oxidation and reduction responsible for the removal and retention of pollutants. These processes are supported by sorption, sedimentation and assimilation. Thanks to these advantages, treatment wetland systems have been used in communal management for over 50 years. In recent years, thanks to its advantages, low operational costs and high removal efficiency, there is growing interest in the use of constructed wetlands for the treatment or pre-treatment of various types of industrial wastewater. The study analyzes current use of these facilities for the treatment of industrial wastewater in the world. The conditions of use and efficiency of pollutants removal from readily and slowly biodegradable wastewater, with special emphasis on specific and characteristic pollutants of particular industries were presented. The use of subsurface horizontal flow beds for the treatment of industrial wastewater, among others from crude oil processing, paper production, food industry including wineries and distillery, olive oil production and coffee processing was described. In Poland constructed wetlands are used for the treatment of sewage and sludge from milk processing in pilot scale or for dewatering of sewage sludge produced in municipal wastewater treatment plant treating domestic sewage with approximately 40% share of wastewater from dairy and fish industry. In all cases, constructed wetlands provided an appropriate level of treatment and in addition the so-called ecosystem service.

Induced by stringent standards for surface and drinking water, a cadmium balance for the Ruhr river basin has been calculated. This balance indicates the dominating impact of industrial wastewater discharge while the cadmium load of other sources is comparatively small. In order to reduce cadmium concentrations in river water and in sewage sludges and to avoid disturbances in municipal wastewater treatment plant operation, a control strategy has been developed to identify discharges under cover of darkness and to consult the particular industries. First positive results are dealt with.

In the western part of Germany there are 77 full scale anaerobic treatment plants treating industrial wastewater. The ISAH (Institut für Siedlungswasserwirtschaft und Abfalltechnik at the University of Hannover) is or was involved in the investigations, the design and/or operation of 14 of these plants. Some industries (sugar beet, starch, pectin, brewery, vegetable) with their special problems with treating their wastewater anaerobically are described. Experiences of how to handle high nitrate concentrations, to treat a mixture of several industrial wastewaters, to prevent or handle lime, magnesium ammonium phosphate (MAP) or aluminium precipitations are reported. The first municipal wastewater treatment plant combined with a separate anaerobic stage to treat a wastewater mixture of several small factories is described. Something very special about this plant is the construction of the acidification tank. Using the “teapot effect” to enrich the solid material in the centre of the bottom, the solids can be taken from the bottom of the tank and pumped to the municipal sludge digester.

In this paper, the dry filtration process is described. In the experimental part, the results of tests on the semi-technical scale are presented. Additionally to the determination of material parameters and characteristics of different filter materials, their back wash characteristics are examined. The biofilm on the filter material desired in wastewater technology causes a reduction of 20% of the necessary back wash velocity. On the other hand, mixing phenomena in dual-media filters were increasingly observed. The tests concerning nitrification performance showed that the dry filtration system is an extraordinarily efficient process. Volumetric degradation performances of up to 1.5 kg NH4-Nel/m3d were achieved. Volumetric load and filter velocity turned out to be decisive measurement parameters. In the second part of this paper a dry bed filter plant on a large- technical scale of a municipal wastewater treatment plant is presented. The plant is described, operating results are discussed and operating problems are discussed

In Germany, there are currently 106 full-scale anaerobic treatment plants treating industrial wastewater. This paper describes the operational experiences of several industries (beet sugar, starch, pectin, brewery, distillery, vegetable) which undertake anaerobic wastewater treatment, with particular emphasis on specific wastewater problems and their solutions. Also presented are experiences of the handling of high nitrate concentrations, with the treatment of mixtures of industrial wastewater from different origins, with the chance to prevent the emergence of lime, magnesium ammonium phosphate (MAP) or aluminium precipitation. This paper deals with the first municipal wastewater treatment plant combined with a separate anaerobic stage to treat a wastewater mixture of several small factories. One particular asset of this plant is the construction of the acidification tank: using the “teapot effect” to enrich the solid material in the centre of the bottom, the solids can be taken from the bottom of the tank and pumped to the municipal sludge digester.

This paper presents a methodology that uses a knowledge base and inference procedures for developing rational wastewater management schemes for small to medium size communities with emphasis in the protection of human health, the reuse of treated wastewater, and the pollution minimization of water receivers. The system provides an optimal year-round treatment/reuse/disposal plan, which maximizes the wastewater reuse for irrigation, meets the applicable minimum municipal wastewater treatment requirements and observes the water quality standards of receivers with the minimum treatment costs. The solution is dynamic in the sense that varying monthly design values can be assigned to the input variables used in the computation of irrigation requirements, assimilative capacity of receivers and performance of natural systems. The above procedure shows that the use of multiple receivers over the year is often highly advantageous; combining for example the increased treatment efficiency and reuse potential for irrigation during summer with the increased assimilative capacity of a river during winter. The expert system incorporates a number of design and ambient quality models, for which graphical solutions have been developed, so as to enable manual application if desired. The entire procedure is implemented in an integrated computer program that facilitates and refines problem solution. The expert system provides interactive guidance for collecting the necessary field information. Finally, the results of a case study for the management of wastewaters from the six communities of the Municipality of Keramoti are presented.
