  • Treatment of arsenic-contaminated water using in-line electrolysis, co-precipitation and filtration in Costa Rica

    A novel treatment was tested with groundwater to investigate its arsenic removal under natural conditions. The system utilised in-line electrochlorination to oxidise water constituents without the need for external chemical supply. The oxidised arsenic and iron co-precipitated and were filtered via Greensand Plus™. The filter was catalytically active and provided an emergency oxidant. The ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Novel pretreatment enables performance of MBR installed to treat oily wastewater

    Abstract Two new integrated systems processes, gas-energy-mixing (GEM) flotation – electrochemical catalytic oxidation (ECO) – membrane bioreactor (MBR) and ultra-filtration (UF) – ECO – MBR, were tested in industrial-scale pilots of 200L/h to 3000L/h for the treatment and reuse of steel mill cold-rolling emulsion wastewater. The operation parameters and mechanisms of ...

  • 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 ...

  • Ten top growth markets in air, water and energy

    For suppliers of products and services for the air, water, and energy industries there are some substantial double-digit growth opportunities.

  • Nature inspires a better way to block biofilms

    In many industries where equipment comes in contact with water, including those that rely on water treatment membranes, equipment fouling is a huge problem. Biofilm fouling occurs when living organisms — including bacteria, algae, and even mollusks — become attached to boat hulls, harbor structures, and other equipment. The resulting damage can be costly. Coatings and other chemical ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...
