  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
