  • Looking Back at the Water Industry in 2017 — And Looking Ahead

    Another year came and went, and we are now well into a new one, facing the approach of spring and construction season. 2017 brought about both accomplishments and new challenges not just for us here at AdEdge Water Technologies, but also for the water industry as a whole. Looking ahead at what’s to come in 2018, changing regulations and standards may pose challenges for water utilities and ...

  • 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 ...

  • A novel image processing-based system for turbidity measurement in domestic and industrial wastewater

    Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at wastewater treatment plants (WWTPs) requires the development and implementation of appropriate performance metrics; particularly those that are easily measured, strongly ...

  • Scale-up of a packed bed column for wastewater treatment

    After checking the success of the biosorption process to remove heavy metals from wastewater using olive tree pruning as a cheap biosorbent in the laboratory scale, the scale-up is necessary to progress towards industrial applications chance. The aim of this work was the study of the effect of scale-up in the process of biosorption of Pb(II) with olive tree pruning in a packed bed column. ...

  • Hexavalent chromium removal from municipal wastewater using ferrous salts

    Hexavalent chromium is difficult to remove during conventional biological wastewater treatment. This is because the hexavalent form is dissolved and is only sparingly removed by adsorption onto biomass in conventional processes. Hexavalent chromium is of particular concern because of its aquatic toxicity, and an increasing number of wastewater works have effluent discharge limits to protect ...

  • Could EB irradiation be the simplest solution for removing emerging contaminants from water and wastewater?

    Newly observed presence of ‘emerging contaminants’, defined also Compounds of Emerging Concern, chemicals without regulatory status and which impact on environment and human health are poorly understood has been amply reported in wastewater and aquatic environments. ‘Conventional’ water pollutants have been described for decades and their impact on human health and the environment are known; ...

  • Removal of antibiotic resistant E. coli in two Norwegian wastewater treatment plants and by nano- and ultra-filtration processes

    The effectivity of different treatment stages at two large wastewater treatment plants (WWTPs) located in Oslo, Norway, to remove antibiotic resistant Escherichia coli from municipal wastewater was investigated. The WWTPs were effective in reducing the total cultivable E. coli. The E. coli in WWTP samples were mainly resistant to ampicillin (6–27%) and ...

  • Seasonal movement of trace-element discharge in a typical south-Indian suburban community

    Four conventional activated sludge sewage treatment plants (STPs) in Southern India were chosen to investigate the occurrence of major ions and trace metals in dissolved fraction of the wastewater. Samples were collected from inlet and outlet of STPs during the pre-monsoon and monsoon seasons. Except for a few elements (Mn, Mo and Ni), the concentrations of the rest increased at the outlet of ...

  • Rapid Monitoring of Municipal Wastewater Primary Effluent - Case Study

    The primary effluent of a Municipal Wastewater Treatment Plant (MWWTP) is monitored to understand organic loading going to the next stage of treatment, the activated sludge process. This process removes organics via consumption by microorganisms living in the sludge. Knowing the composition of incoming primary effluent is important to prevent organic overloading and improve process optimization ...

  • Process auditing and performance improvement in a mixed wastewater–aqueous waste treatment plant

    The wastewater treatment process is based on complex chemical, physical and biological mechanisms that are closely interconnected. The efficiency of the system (which depends on compliance with national regulations on wastewater quality) can be achieved through the use of tools such as monitoring, that is the detection of parameters that allow the continuous interpretation of the current ...

  • Replacing brush rotors with AIRE-O2 TRITONS increases flow capacity and reclaimed water availability - Case Study

    Overview In 2012, the Middlebury, Indiana Wastewater Treatment Plant (WWTP) was faced with aging brush rotors and higher loads in their oxidation ditch system. When Mick Reese was hired as Plant Superintendent, the upgrade design was about 90% complete. The full system upgrade included adding an outer ring to the existing oxidation oval, construction of a new clarifier, controls ...

  • Special chemical-physical process treats Tata Steel`s wastewater

    Tata Steel Europe manufactures several types of packaging steel. One of the types is Electrolytic Chromium Coated Steel (ECCS). Until recently, a chemical containing chromium-6 was used to manufacture ECCS. Annex XIV of the REACH prohibits the use of chromium-6 with effect from 21 September 2017. It remains possible to apply for an exemption, but only a temporary one. Tata Steel looks to offer ...

  • Dissolved Solids and Water Purification

    To make drinking water palatable, the level of dissolved substances (TDS) can’t be too high, but it also can’t be too low Water quality metrics are needed to ensure that surface and groundwater – common sources of water for human consumption – are free from contaminants and pollutants. The level of dissolved solids, also commonly referred to as total ...
