  • Recent Papers on Industrial Effluents

    This study offers a solution for reducing the environmental effect of wastewaters generated by the olive-oil industry. Olive-oil companies produce variable quantities of wastewaters, which require treatment for disposal or reuse. Today, regulations are becoming increasingly strict regarding the parameters measured in these effluents. In Spain, the resolution by the ...

  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...


  • Partial Effluent Reuse in the Food Industry

    Faced with increasing pressures on groundwater sources, a Belgian frozen food processing company is reusing its effluent in order to reduce its water supply ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Anaerobic effluent treatment at a chemical industrial complex

    In order to test the feasibility of anaerobic treatment of an effluent from a chemical factory producing intermediates for synthetic fibres, test work with a 45 l UASB pilot plant was conducted. After conducting a successful pilot study a full-scale anaerobic effluent treatment plant including a 400 m3 combined buffer/pre-acidification tank and a 990 m3 Biopaq®-UASB reactor was constructed. The ...

  • Toxicity reduction in industrial and municipal effluents – the state of the art

    Developments in treatment technology have traditionally focused on removal of specific contaminants: BOD, solids, ammonia, TOC and lately, specific organics such as phenol. A limit on effluent toxicity, however, does not fit so neatly into a procedural package, since it truly integrates the presence and impacts of contaminants in a sample. Toxicity reduction evaluation procedures, therefore, are ...

  • Wastewater effluent characteristics from Moroccan textile industry

    The objectives of this work were to carry out a complete characterization of textile wastewater, resulting from a textile unit located in the Marrakesh region. A physico-chemical characterization has been performed, focused on organic and toxicological aspects. The cladoceran Daphnia magna was used as the sensor organism and lethal concentration as a criterion to measure the toxicity of ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...

  • System for bioremediation of effluents

    Executive Summary The remediation process of commercial, municipal, industrial and agricultural wastewaters has employed combinations of sulfuric acid, caustic, petroleum based solvents and synthetic emulsifiers, which are either toxic or generally non-biodegradable. An alternate method using naturally occurring microorganisms has been utilized for many years to facilitate the remediation ...

  • Removal of cadmium from industrial effluents by electrocoagulation process using iron electrodes

    Heavy metal species are some of the most common pollutants that are found in industrial wastewaters. Because of their toxicity, these species can have a serious impact if released into the environment as a result of bioaccumulation, and they may be extremely toxic even in trace quantities. One such a heavy metal, cadmium, along with its compounds, is widely used in pigments, as heat stabilizers ...

  • Studies on Heavy Trace Metal Ions in Industrial Waste Effluents in Pakistan

    The impairment of water quality due to introduction of industrial pollutants is a major problem faced by big industrial cities. The uncontrolled release of waste effluents to large water bodies have deleterious effects both on water quality and aquatic life. In our country, Karachi, the largest industrial city, is facing a similar problem. The aim of the present work is to determine the levels of ...


  • Compact combined anaerobic and aerobic process for the treatment of industrial effluent

    A novel combination of tall and slender tanks and reactors has been installed at the Grolsch brewery, located in the urban area of Enschede, The Netherlands. Specific design was required to meet very strict constraints with respect to space, odours, view and biosolids production. The plant consists of buffering, anaerobic and aerobic treatment, whereas sludge handling is not required. The design ...

  • Dissolved radionuclide in the industrial effluent of uranium facilities, Jaduguda, India

    Dissolved radionuclides in the effluent of uranium mining industry were studied. Activity concentrations of uranium and radium were estimated in effluent water from different uranium mines and mill tailings ponds. The concentrations of U and 226Ra in untreated effluent water were found to be elevated. The concentrations of dissolved radionuclides in the adjacent aquatic ...

  • Cost benefit analysis of measures to reduce industrial effluent discharges

    In an environmentally harmonized society the most cost effective measures to reduce the total effluent discharges should be taken into account. Generalised discharge values are presented for organic material and nutrients in this paper. Depending on conditions in the receiving water any of these parameters can be the determining factor for the eutrophication and oxygen demand. These parameters ...

  • Water quality of a stream receiving industrial effluents, located in the Brazilian Northeast

    Industries, as a source of pollution, have a considerable impact on water resources due to the diversity in the composition of their effluents. The Mussure Stream was chosen for this study because it flows across the industrial district of Joao Pessoa, in Northeast Brazil, and is the main receiver of liquid effluents, which are disposed into the stream almost exclusively without adequate ...
