  • Filtration and manganese removal

    Manganese removal through a filter bed is generally carried out and accepted by practitioners and researchers as occurring through catalytic oxidation at the surface of MnO2 coated media, although manganese passage through a coated media filter has been little investigated. To better understand the kinetics of Mn removal through a naturally coated filter, a pilot plant consisting of four filter ...

  • Modification of tubular ceramic membranes with carbon nanotubes using catalytic chemical vapor deposition

    In this study, carbon nanotubes (CNTs) were successfully grown on tubular ceramic membranes using the catalytic chemical vapor deposition (CCVD) method. CNTs were synthesized at 650°C for 3–6 h under a 120 mL min−1 flow of C2H6 on ceramic membranes impregnated with iron salt. The synthesis procedure was beforehand optimized in terms of catalyst amount, impregnation duration ...

  • AD26 System Performance – Iron / Manganese - Confidential Client - California

    In the early 2004, AdEdge was engaged by Pacific Advanced Civil Engineers (PACE) to devise a treatment alternative for manganese and iron removal for a public water system in southern California. This high demand water supply well was yielding between 180 to 220 gpm. The needs were imminent as the currently designed system was not achieving compliance with the Safe Drinking Water Act secondary ...

  • Effectiveness of oxidative filter materials for manganese removal from groundwater

    The experiments reported in this paper were conducted at a pilot plant consisting of filtration columns filled with oxidative filter materials. The installation was supplied with water containing manganese in concentrations ranging from 0.2 to 1.4 mg/L. The aim of the experiments was to determine the effectiveness of manganese removal on the three filter media as a function of their internal ...

  • Certain requirements for fuel blending

    Fuel, as well as all products, has certain requirements: it shouldn’t change the structure during the transporting and storage, to cause a deposit and gumming on engine parts, to intensify corrosion processes, to have the increased toxicity. Operation reliability of any engine, its capacity, durability, toxicity of exhaust in many respects depends on fuel quality. Commodity gasoline ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • Project profile - troyer water system – Middlefield, Ohio arsenic, iron & manganese removal

    Background In early 2008, AdEdge was selected by EcoWater Servisoft in Burton, Ohio to design, build, and startup an integrated treatment system to remove arsenic, iron, and manganese levels at the Troyer Water System in Middlefield to below the primary and secondary MCLs of 0.010 mg/L, 0.3 mg/L and 0.05 mg/L respectively. AdEdge first piloted a treatment system in spring of ...

  • Removing Chloramines from Drinking Water Supplies

    Historically, most public water supplies have been treated with chlorine to satisfy the standards set by the Safe Drinking Water Act of 1974. Since being established, there is reason to believe that the standards may be too lenient on the allowable contaminant levels in our drinking water. For instance, chlorine and other disinfectants react with organic matter creating ...

  • Project profile - Melody Woods Water Company Los Gatos, California iron and manganese treatment system

    Background In February 2009, the Melody Woods Water Company selected and began working with AdEdge Technologies to assist with the design and implementation of a Manganese, Iron and Turbidity treatment system to serve the water supply for Melody Woods in Los Gatos, California. The site has two existing groundwater supply wells that provide drinking water for approximately 53 connections ...

  • Difficult Complex Decisions For Coal-fired Power Plant Operators

    Changing fuel prices, government regulations and technology all combine to make decision making difficult for operators and developers of coal-fired power generation facilities around the world. Power plant designers in developing countries face new local environmental regulations plus additional requirements stipulated by lenders such as the World Bank. In the developed world, the regulations ...

  • Project profile - Village of Corona, NM iron and manganese reduction

    Background In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. The water system that serves approximately 100 connections at Corona was plagued by high iron and manganese in the main water supply with iron from 0.26 – 2.8 mg/L and manganese levels from 0.094 - 0.17 ...

  • Project profile - Blue Rhino Hamptonville, NC

    Background In 2007, Blue Rhino, located in Hamptonville, NC, contacted AdEdge Technologies, Inc. (AdEdge) to install an iron and manganese treatment system. The amount of iron (5.6 mg/L Fe) and manganese (0.6 mg/L Mn) were well above the maximum contaminant levels of 0.3 mg/L Fe an 0.05 mg/L Mn respectively. The pH of the Blue Rhino site (6.10) was quite below the maximum contaminant ...

  • Case study - Bi-On Carb OX: Odor treatment in WWTPs. Case study SIMTEJO (Portugal)

    Avoiding problems associated with foul odors in and around collectors and waste water treatment plants is today one of the major focus points to avoid possible issues related to worker safety, as well as minimizing negative social discomforts caused by the foul odors. The main sources that generate foul odors in WWTPs occur at stages of anaerobiosis, where the lack of oxygen favours the ...

  • Case study - Meat processing odor control

    Overview For its first two years of production, a food manufacturer based in South Wales, England, focused its production on potatoes. Neighborhood residents voiced no complaints about odors during this time period. However, as new production lines (including barbequed meats and curried chicken) were added, the complaints began, and it became clear that odor abatement equipment was needed ...
