Daurala has ...

  • How Do You Know If An Industrial Facility Needs a Wastewater Treatment System?

    Not properly treating wastewater can potentially harm the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It can also cause a company to incur heavy fines and possible legal action if wastewater is being improperly discharged into a POTW (publicly owned treatment works) or to the environment (usually under a National Pollutant ...

  • 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 ...


  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Mining, the environment and the treatment of mine effluents

    The environmental impact of mining on the ecosystem, including land, water and air, has become an unavoidable reality. Guidelines and regulations have been promulgated to protect the environment throughout mining activities from start-up to site decommissioning, in particular, the occurrence of acid mine drainage (AMD), due to oxidation of sulfide mineral wastes, has become the major area of ...

  • 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 ...

  • Removal of Chromium From Effluents of Tanning Industries and its Reuse

    Air and water are the basic needs of human being and other living entities on the earth. Tanning industry uses water and some chemicals and so creates environmental problems, depending basically on two principal sources, hide and water. The processes of tanning are based on chromium sulphate and vegetable treatment of hide. According to the national environment quality standards (NEQS) the ...


  • Pb and Co removal from paint industries effluent using wood ash

    The release of heavy metals into the environment is a worldwide major concern. Different studies have demonstrated that natural agents have a high removal capacity for divalent heavy metal ions. Wood ash is a natural adsorbent and, in comparison with others, has a very low price. In this study, the removal of heavy metals (Pb and Co) from Binalood paint industry (Kerman, Iran) effluent was ...

  • A review on the use of biopolymers for the removal of toxic metals from liquid industrial effluents

    Various industrial processes such as mining, metal plating, metal finishing, and chrome tanning discharge many chemicals and heavy metals into the plant effluent stream. In view of this, the need of developing viable and relevant technologies that can not only cleanup but also recover valuable components from industrial and biological waste streams is of utmost importance.
