  • Advanced treatment of Membrane Bioreactor (MBR) effluents for effective wastewater reclamation

    One of the two main objectives of this work is to oxidize MBR effluents with ozone/peroxide in high pH conditions in order to improve oxidation of pharmaceuticals, which could efficiently be rejected by the nanofiltration (NF) stage. The other main objective is to effectively oxidize of dissolved organic carbon (DOC) in MBR effluents in order to decrease fouling in the filtration stage. In this ...

  • Water reuse for the bottled water industry

    ABSTRACTThe bottled water industry uses a machine specifically designed for the washing of its containers (19-L capacity) and generates 6-L wastewater/container. This effluent can be used for watering of green areas and car washing. The objectives of the present work were to characterize the effluent and to propose a specific treatment to enable reuse of the effluent from the container washing ...

  • Project profile - arsenic treatment project Pueblo of Isleta, New Mexico

    Background In August, 2004, following successful field piloting, AdEdge Technologies, Inc. (AdEdge) was selected by the Pueblo of Isleta, located south of Albuquerque, New Mexico, to provide a turnkey project for furnishing an arsenic treatment system, installation, startup, and commissioning to bring the casino water system into compliance with the new maximum contaminant level (MCL) for ...

  • Data Requirements for Ground Water, Surface Water, and Leachate

    It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

  • Industrial Laundry-3

    The facility was trying to expand its market share by increasing the industrial linen operations. The facility washes a combination of ‘clean’ linens as well the ‘heavy’ linens from industrial clients in the form of shop towels, bar mops, and printer towels. The pretreatment system included the use of a 93% sulfuric acid, coagulant, calcium chloride for increased solids and settling rate, lime ...

  • Modeling Strategy for SBR Recovery after Upset

    The paper presents results of treatability study on wastewater highly contaminated with ammonia (800 mg/l), (phenols (300 mg/l), thiocyanate (210 mg/l), and arsenic up to 11 mg/l. The study was conducted in two sequencing batch reactors (SBRs) using biomass from a coke plant. After two months of acclimatization the biomass was able to remove ammonia to below 1 mg/l and phenols and thiocynate ...

  • Waste water treatment costs reduced by 50% with rotary vacuum precoat filter - Case Study

    Problem: The solids separation system at Lindc's waste water treatment facility had high operating, maintenance and sludge disposal costs. High operating costs were caused by the large pumps and special treatment chemical required to operate the filter, and frequent cleaning, repair and replacement of filter elements resulted in high maintenance costs. Union Carbide Corporation's Linde ...

  • A built-in zero valent iron anaerobic reactor to enhance treatment of azo dye wastewater

    Waste scrap iron was packed into an upflow anaerobic sludge blanket (UASB) reactor to form a zero valent iron (ZVI) - UASB reactor system for treatment of azo dye wastewater. The ZVI acted as a reductant to decrease ORP in the reactor by more than 40 mv and functioned as an acid buffer to increase the pH in the reactor from 5.44 to 6.29, both of which improved the performance of the anaerobic ...

  • Improving GAC efficiency

    PROJECT BACKGROUND: A Superfund Site located in the Northeast US was previously used for reclaiming and re-refining waste oils from 1945-1985. A TSCA inspection uncovered the presence of PCB’s in several lagoons onsite. The site had seven lagoons containing over 9,000,000 gallons of water and oil. Due to heavy rains, the lagoons fill frequently. Therefore, several emergency removal actions were ...

  • Evaluation of wet air oxidation variables for removal of organophosphorus pesticide malathion using Box-Behnken design

    This paper deals with finding optimum reaction conditions for wet air oxidation (WAO) of malathion aqueous solution, by Response Surface Methodology. Reaction conditions, which affect the removal efficiencies most during the non-catalytic WAO system, are: temperature (60–120 °C), applied pressure (20–40 bar), the pH value (3–7), and reaction time (0–120 min). Those were chosen as independent ...

  • Investigation of chemical-free nutrient removal and recovery from CO2-rich wastewater

    The feasibility of a bench-scale system for removal and recovery of phosphorus (P) as struvite from CO2-rich wastewater was tested. A continuous 12 L reactor system combining a fluidized seedbed and aeration for pH increase was developed and tested using synthetic feed. For a 100 mL min−1 influent rate, an aeration and recycle rate combination of 7 L min−1 and ...

  • Sustainable groundwater management using reclaimed water: the Torreele/St-André case in Flanders, Belgium

    The Torreele facility produces infiltration water for indirect potable re-use through artificial recharge of the dune aquifer of St-André. The secondary wastewater effluent is treated by ultrafiltration (UF), using the submerged ZeeWeed system, prior to reverse osmosis (RO), using brackish water low energy membranes. The Torreele experience showed that combining UF and RO enables the ...
