  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • On-site Neutralization of Laboratory Wastewater: Northern Territory University

     The Northern Territory University’s Faculty of Science have designed and installed a ‘Neutralization Pit’ as their ‘cleaner production initiative. The primary objectives of the Northern Territory University adopting this form of treatment for the chemical wastewater generated by the Faculty of Science was to: Prevent pollution and eutrophication of the receiving Darwin watercourses as ...


  • Microbiology: The Key to Wastewater treatment case study

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. The fecal bacteria that are constantly introduced into the collection system are not the optimal bacteria for degrading the contaminants present in wastewaters. The soil bacteria that are introduced through inflow and infiltration are more effective at degrading the wastes and can ...

  • Sequential anaerobic–aerobic biological treatment of colored wastewaters: case study of a textile dyeing factory wastewater

    In the present study the feasibility of the use of a bacterial batch sequential anaerobic–aerobic process, in which activated sludge was used in both parts of the process, for pretreatment of wastewater generated by a textile dyeing factory has been considered. Activated sludge used in the process was obtained from a municipal wastewater treatment plant and adapted to real dyeing wastewater ...

  • Potential reuse of a leather tanning and an urban wastewater treatment plant effluent in Italy

    This study aimed to evaluate the potential reuse of a leather tanning district and an urban wastewater treatment plant (UWWTP) effluents. The UWWTP discharges into the Sarno river which is one of the most polluted river in Europe. A water restoration program covering the rationalisation of the water use between industry and irrigation is in progress for this river. However, no use for fire ...

  • Treatment Of High Strength Chemical Industry Wastewater Using Moving Bed Biofilm Reactor (MBBR) and Powdered Activated Carbon (PAC) Technology

    A new Waste Recycling Facility (WRF) was created at the Sasol coal to liquids facility in Secunda, South Africa with a wastewater treatment system that includes equipment to treat the wastewater and storm water through several steps including equalization, oil removal (gravity separation and dissolved air flotation), lime neutralization/metals precipitation, back-neutralization, fixed-film ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Electroplating Industry - Pollution Prevention Guidelines

    Introduction Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum ...

  • Decentralized wastewater management in Kieu Ky Vietnam

    1. Overview and Key Points In order to eliminate the common ‘out of sight out of mind approach’ in sanitation, whereby sewers and/or drains are discharged into rivers, a Decentralized Wastewater Treatment System (DEWATS) was designed and implemented in Kieu Ky to treat wastewaters arising residential properties and various craft industries. A clear understanding of topography, ...

  • Information you should about food processing wastewater treatment

    Wastewater is water which has been “utilized”, for this situation, amid sustenance and refreshment preparing. This utilized water must be dealt with or handled so it meets every single pertinent control before it can be released, or sometimes reused. As of late, as controls have fixed and innovations progressed, conventional sewage treatment gear is being supplanted or increased with ...

  • Case Study: Heavy Industrial Laundry

    This facility washes heavily soiled towels from the ink printer and furniture polishing industries. The wastewater generated is very concentrated with metals and hydrocarbons making it difficult to treat in their DAF pretreatment system. The facility was using conventional chemistry with sulfuric acid, organic/inorganic coagulant, metal precipitant,flocculant, and Harborlite (filter press ...

  • Treatment of reactive dyes and textile finishing wastewater using Fenton's oxidation for reuse

    Fenton's oxidation (FO) was used to decolourise and degrade some reactive dyes (Remazol Black 5, Remazol Red, Remazol Blue, Remazol Yellow) and raw textile finishing industry effluents (S1, S2, S3) containing mainly reactive dyes. The operational conditions for pH varied between 2.5 and 4.0 while temperature ranged from 30°C to 50°C. The concentrations of FeSO4 and ...

  • Removal of ecotoxicity and COD from tank truck cleaning wastewater

    Tank truck cleaning (TTC) activities generate highly complex wastewater. In a previous study, we found that a significant ecotoxic effect was still present in biologically treated TTC wastewater. The aim of the present study was therefore to investigate the removal of acute toxicity from TTC wastewater by a sequence of technologies routinely applied for industrial wastewater. Acute toxicity was ...
