  • Coupling of anodic oxidation and adsorption by granular activated carbon for chemical oxygen demand removal from 4,4′-diaminostilbene-2,2′-disulfonic acid wastewater

    Experiments were performed to reduce chemical oxygen demand (COD) from 4,4′-diaminostilbene-2,2′-disulfonic (DSD) acid manufacturing wastewater using electrochemical oxidation coupled with adsorption by granular activated carbon. The COD removal is affected by the residence time and applied voltage. When the residence time is increased, lower value of COD effluent could be obtained, however, the ...

  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • Chlorine removal with KDF 55 - Case Study

    KDF 55 Process Medium Helps with Removing Chlorine in a Municipal Water Treatment Facility A Los Angeles-based maker of fashion jeans uses KDF media instead of chemicals for removing chlorine when treating municipal water in their stone-washing process. High-purity copper-zinc redox water filter media consistently provides 99% of free chlorine removal from water by ...

  • Vapor Intrusion Issues Risk Occupants’ Health

    Vapor intrusion occurs when a gaseous substance migrates into a building.  For example, volatile organic compounds and other gases can migrate from contaminated soils and groundwater through cracks in foundations or sewer lines and enter a building.  Vapor intrusion can create an indoor environment that damages structural materials and puts building occupants’ health at ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • Water treatment helping cars stay cool - automotive industry: Orlando, Florida

    A manufacturer of air-conditioning line connectors for automobiles was required by the city to meet new sewer discharge standards. They had been using a system of gravity separation which did not address suspended solids or soluble metals. Their wastewater is generated from 3 sources; mop water, parts deburring and polishing, and floor scrubber water. They generate approximately 6,000 gpd of ...

  • Treatment of high strength resin production wastewater case study

    Problem Full-scale Incineration of this wastewater had proved very expensive due to the fuel input required and the ongoing incinerator maintenance costs. The polymer manufacturer sought treatment alternatives to save money. Initial biotreatment pilot work indicated that biotreatment was not feasible using conventional activated sludge technology even when the concentrated wastewater was ...

  • Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate

    Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Tackling remediation emissions

    Organisations commissioning regeneration projects now have the option to substantially reduce the carbon emissions associated with any remediation project, while offsetting the remaining carbon impact of these works, says Joe Teer, operations director of QDS. QDS introduced a carbon neutral remediation (CNR) service earlier this year triggered at this particular time by the fact ...

  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...
