  • Food & Beverage Industry: Soft Drink - Case Study

    The peCOD (photoelectric Chemical Oxygen Demand) method for COD analysis is well suited to the soft drink industry as it provides plant operators with quick and reliable COD results important for process monitoring and control. Continuous COD monitoring of wastewater can protect production plants by ensuring COD discharge levels meet the acceptable limits, and by detecting product leakage. It can ...

  • Efficient reduction of chemical oxygen demand in industrial wastewaters

    Depending on the industry activity and the situation, maximum chemical oxygen demand (COD) levels between 200 and 1000 mgO2/l (ppmO2) must be reached in order to release the wastewaters back into the environment [1]. Wastewater treat-ment technologies, such as filtration, biological digestion, or incineration exist but these technologies are either expensive or generate sludges which must be ...


  • On-site industrial wastewater treatment

    Priority pollutant behaviour in on-site treatment systems for industrial wastewaters The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • What Is Industrial Wastewater Treatment?

    Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

  • Canarina DESCAR software · wastewaters · complex organic chemicals industry · commands 6

    In the center of the program window, we will draw and we will calculate the different polluting processes. We can draw using two different planes: parallel to the surface of the water (XY) and perpendicular to the surface of the water (XZ). There is a grid in the XY-plane. The coordinate origin is on the left bottom corner (X=0, Y=0) in XY-planes (parallel to the surface of the water). In ...

  • An overview of wastewater treatment in distillery industry

    Distilleries generate large volumes of high-strength wastewater that is of serious environmental concern. Spentwash disposal even after conventional treatment is hazardous and has high pollution potential due to the accumulation of recalcitrant compounds. Various physico-chemical and biological treatment options are available for the treatment of distillery wastewaters, but most of them could not ...

  • Wastewater pre-treatment in a confectionery industry

    Description of the plant In a first step, wastewater accruing from the production of marzipane is cleaned by a screen. As flow and load to the plant are highly variable depending on the production process an aerated mixing and balancing reactor has been installed to equalise flow and load before final chemical pre-treatment. After adding of chemicals for precipitation and flocculation ...

  • Central treatment of the industrial wastewater in Kuwait

    Description of the plant In order to treat the wastewater accumulating from all industrial plants located in Kuwait, TIA planned and built up a central Wastewater Treatment Plant in the Kuwaiti desert. The plant consists of three receipt stations, three pre-treatment lines and two lines for biological wastewater treatment. Each day, 200 to 400 tank trucks deliver the ...

  • Industrial Wastewater Treatment - Paint/Pigment Dye Industry

    Innovation in Industrial Wastewater Treatment - Sustainable Water Reuse Strategies Applied to the Paint/Pigment Dye Industry Introduction The paint/pigment industry is a large consumer of process and wash water to be used in various water based paint pigment products. The water usage for this industry is estimated at 75-85 million gallons per day, with ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Chemical fractionation and speciation modelling for optimization of ion-exchange processes to recover palladium from industrial wastewater

    Palladium is used in several industrial applications and, given its high intrinsic value, intense efforts are made to recover the element. In this hydrometallurgic perspective, ion-exchange (IEX) technologies are principal means. Yet, without incorporating the chemical and physical properties of the Pd present in real, plant-specific conditions, the recovery cannot reach its technical nor ...

  • AOX removal from industrial wastewaters using advanced oxidation processes: assessment of a combined chemical–biological oxidation

    In this paper, the abatement of adsorbable halogenated organic compounds (AOX) from an industrial wastewater containing relatively high chloride concentrations by a combined chemical and biological oxidation is assessed. For chemical oxidation, the O3/UV, H2O2/UV and photo-Fenton processes are evaluated on pilot scale. Biological oxidation is simulated in a 4 h respirometry ...

  • 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 ...
