  • In-Situ Treatment - Funnel & Gate System - Case Study

    Problem An asphalt testing facility, in operation for many years, closed in the early 1990s. A subsequent environmental assessment revealed that an underground storage tank, used to hold common cleaning/degreasing solvent for use during testing, had developed a leak and had to be abandoned. The storage tank and soil in the immediate vicinity was removed as the first step to remediate ...

  • Enhanced phosphorus removal by microbial-collaborating sponge iron

    The collaborative and mutually reinforcing phosphorus removal in domestic wastewater in a sponge iron and microorganisms system was studied through a laboratory and a pilot scale experiment. The results showed that the total phosphorus concentration of the effluent of less than 0.5 mg/L could be achieved. The results also support that the biochemical reaction accelerated the iron ...

  • One process removes arsenic & iron from water in small Utah town

    The Safe Drinking Water Act brought with it tough arsenic compliance standards, forcing cities large and small to comply with a maximum contaminant level of 10 parts per billion (ppb) or face stiff fines and even the potential shutdown of wells. Smaller towns such as Cannonville, Utah, face the most difficult challenge, due to manpower and budget constraints. Cannonville turned to Filtronics, ...

  • Optimal synthesis and nitrate and mercury removal ability of microemulsion-made iron nanoparticles

    Controlled preparation of iron nanoparticles through reduction of Fe3+ ions is investigated, using potassium borohydride solution in a microemulsion system. The effect of three low-cost cationic, anionic and non-ionic surfactants at various concentrations on the size of prepared iron nanoparticles is studied. Results show that the anionic surfactant, sodium dodecyl sulfate (SDS), significantly ...

  • DEFERUM high iron removal water treatment plant equipment and technology

    DEFERUM is the ONLY technology available to remove HIGH iron (up to 80mg/L) and gas problems in water distribution, potable water and groundwater environments with very low operating costs. DEFERUM is also eco-friendly!Iron is one of the earth's most plentiful resources, making up at least five percent of the earth's crust. Rainfall seeping through the soil dissolves iron in the earth's surface ...

  • Transformation of an existing physicochemical plant for iron and manganese removal by the application of biological processes

    A system for removing iron and manganese in groundwater, based on biofiltration technology, was developed at the Center of Sanitary Engineering of the National University of Rosario, Argentina. This process has been successfully applied in several new water treatment plants in Argentina. This paper describes the transformation of an existing plant for iron and manganese removal in groundwater ...

  • Interactions between ammonia, iron and manganese removal using pilot-scale biofilters

    Pilot-scale biofilters treated with real groundwater were established to systemically investigate the interactions between ammonia, iron and manganese removal. When both of ammonia and manganese in influent were about 1 mg/L, they were quickly removed; but when manganese was above 3 mg/L, ammonia removal was affected significantly. When total iron was above 5 mg/L, the oxidization rate of ...

  • Improvement of phosphorus removal by calcium addition in the iron electrocoagulation process

    Small-scale wastewater treatment plants (SWTPs) are widely used as decentralized wastewater treatment systems in sparsely populated areas of Japan. Iron electrolysis, an electrocoagulation technology, is installed in these SWTPs for phosphorus removal. Phosphorus can be removed via the formation of an insoluble compound containing phosphate and iron, such as FePO4; however, it was necessary to ...

  • One step, low pH iron and organics removal - Case Study

    Review For over seven years, the semiconductor facility performed routine on-site cleans of their reverse osmosis (RO) membranes using RoClean P111 with good results. However, over a six month period in 2015, membrane cleaning frequency increased to once a month and permeate flows could not be sufficiently restored. An Avista application specialist visited the site to personally monitor the ...

  • Biological iron and manganese removal, pilot and full scale applications

    Both manganese and iron are found in surface and ground waters at varying concentration levels. When present even at low concentrations they can be linked to the following problems: discolouration, turbidity and taste problems or form slime and iron noxide or manganese dioxide accumulations in pipes. Both metals promote the growth of certain types of chlorine tolerant micro-organisms in water ...

  • Mild cleaning: removal of 900 kg iron from a cooling water system - within 7 hrs - Case Study

    A professional cooling water treatment prevents the plant from corrosion damages. But in case corrosion should occur, severe damages can be the consequence. The cooling system needs to be cleaned. In contrast to a conventional cleaning with aggressive acids, Kurita suggests an innovative cleaning method: mild, material-protective and effective.   With the mild Kurita cleaning method amazing ...

  • 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 - Brandywine Elementary School New Palestine, Indiana AD26 arsenic, iron, manganese removal system

    Background In July 2009, AdEdge Technologies Inc.

  • Arsenic Removal

    The Arsenic Removal ProcessArsenic, a naturally occurring element, is found throughout the environment; for most people, food is the major source of exposure. Acute (short-term) high-level inhalation exposure to arsenic dust or fumes has resulted in gastrointestinal effects (nausea, diarrhea, abdominal pain); central and peripheral nervous system disorders have occurred in workers acutely ...


  • Hydraulic residence time and iron removal in a wetland receiving ferruginous mine water over a 4 year period from commissioning

    Analysis of residence time distribution (RTD) has been conducted for the UK Coal Authority's mine water treatment wetland at Lambley, Northumberland, to determine the hydraulic performance of the wetland over a period of approximately 4 years since site commissioning.
