  • 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 ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Cadmium removal from industrial effluents by cementation with zinc powder

    This work presents the study of the cementation with zinc of a cadmium containing effluent, as an alternative process to chemical precipitation. The effluent, which was produced in the regeneration cycle of the ion–exchange columns of a metal plating waste–water treatment plant, contains: [Cd(II)] = 3500 mg/L; [Cr(III)] = 1230 mg/L; [Cu(II)] = 4575 mg/L; [Fe(II)] = 985 mg/L; [Zn(II)] = 325 mg/L ...

  • Asbestos in water? How to address ‘non-standard’ samples of industrial and other effluents

    Biohazards and other interferences complicate the employment of off-the-shelf asbestos in water methods by traditional TEM techniques. Laboratories must implement creative strategies to prepare and analyze these samples to produce meaningful analytical data. Laboratory and personnel safety have to be considered before sample handling. The interferences also greatly diminished any reasonable ...

  • A pilot scale electrolytic unit for tertiary treatment of industrial effluents

    Over the past few years, academic research has focused on the development of new treatment technologies for municipal and industrial wastewater that will be suitable for reuse. In this study, an electrolytic pilot scale unit has been manufactured for the tertiary treatment of biologically processed wastewater aiming at its reuse for groundwater recharge or for agricultural purposes. The ...

  • 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 ...

  • 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 ...

  • 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 ...
