  • Fruit Cannery

    This facility cans peaches and pears and wanted to investigate the reduction in BOD and TSS using the Floccin Agents. Samples were made in the off season using 2/3 by weight of peach to 1/3 pear with a total amount of 100 grams in 2,000 ml (5% by weight to simulate the wastewater generated from the facility). The samples were flocculated with Floccin J at a dosage of 0.25 gram/1,000 ml (250 ...

  • Ultrasonic impact on bacterial population in sewage sample

    Nine samples of sewage sludge from different paper mills of New Delhi were treated with ultrasonic waves of two different frequencies, viz., 35 kHz and 130 kHz for different time periods (5, 10, 20 and 30 min). Treated sewage sludge was then evaluated with different parameters, viz., Chemical Oxygen Demand(COD), Biochemical Oxygen Demand (BOD), Total Nitrogen, Total Phosphorus, Total Ammonia and ...

  • Electrochemical treatment of semi-aerobic landfill leachate using Response Surface Methodology (RSM)

    This research investigated the effectiveness of electrochemical treatment in treating semi-aerobic landfill leachate. The electrolytic reactor assembly included a pair of aluminium electrodes, a power supply and NaCl as electrolyte. The interactive effects of initial COD, current density and reaction time on treated leachate quality were studied. Regression equations were developed using ...

  • Effects of open water on the performance of a constructed wetland for nonpoint source pollution control

    The seasonal performance of four differently configured constructed wetland systems was compared for the treatment efficiency of nonpoint source pollution. Dead plants in the constructed wetlands increased the nitrogen removal rate during winter by providing organic carbon, which is essential for the denitrification process. However, when the wetlands released phosphorus from the dead plants, the ...

  • Performance of pilot submerged membrane bioreactor treatment systems in girdwood, Alaska

    ABSTRACT The Anchorage Water and Wastewater Utility (AWWU) has conducted pilot testing of an Enviroquip submerged membrane bioreactor (SMBR) and a ZENON SMBR at the Girdwood Wastewater Treatment Facility (GWWTF) located in Girdwood, Alaska. The Girdwood wastewater is unique relative to other municipal wastewaters in that it is dilute, weak and typically low-temperature. This paper summarizes ...

  • The impact of chlorine disinfection on biochemical oxygen demand levels in chemically enhanced primary treatment effluent

    The response trends of biochemical oxygen demand (BOD) and organic strength after the chlorination/dechlorination process were explored through a 2-year, 5-month chemically enhanced primary treatment (CEPT) effluent onsite monitoring program and a 2-month laboratory-scale study. The monitoring results showed that better instantaneous mixing at the chlorine injection point reduced the effect of ...

  • PeCOD Case Study – Industrial Waste Water

    Clean Harbors is an industrial wastewater treatment facility in Guelph, Ontario. The facility utilizes highly refined, chemical precipitation processes, which remove heavy metals, suspended solids, and organics to generate safe effluent for discharge into municipal sewer systems. Wastewater is treated to meet municipal discharge requirements for biochemical oxygen demand (BOD5). Since BOD is a ...

  • Light Industrial Laundry

    A smaller laundry treating 30,000 gallons/day of wastewater was using conventional chemistry with sulfuric acid to drop the pH to 7.5, addition of a coagulant, and a flocculent. The facility has been under pressure from the POTW to reduce the electroconductivity (EC) levels. Past analytical data has shown that the EC levels have averaged 2,100 μohms/cm from the addition of the laundry ...

  • Poultry slaughterhouse wastewater treatment plant for high quality effluent

    This paper assesses a wastewater treatment plant (WWTP) regarding the technology used, as well as organic matter and nutrient removal efficiencies aiming to optimize the treatment processes involved and wastewater reclamation. The WWTP consists of a dissolved air flotation (DAF) system, an upflow anaerobic sludge blanket (UASB) reactor, an aerated-facultative pond (AFP) and a chemical-DAF ...

  • Development of a water quality assessment model: a water quality assessment model based on watershed characteristics by non-linear regression

    Here, a water quality assessment model (WQAM) is developed by non-linear regression as an alternative to physical watershed modeling in South Korea. Three cases and 10 scenarios are applied and reviewed to determine the most appropriate WQAM. The three cases are: (1) the area size allocation of sub-watersheds, (2) the watershed imperviousness ratio, and (3) the combination of the area size and ...

  • A preliminary study on the environmental condition of the coral reef habitat

    The present investigation was carried in coral reef areas of Palk Bay, Madapam. Palk Bay corals were found disturbed by human beings due to oil pollution, waste discharge from processing units and discharge of domestic household wastes from the nearby Mandapam town. Environmental conditions of the coral reef habitat in the Palk Bay, Mandapam was analyzed for a period of six months at fortnightly ...

  • Quality and first flush analysis of stormwater runoff from a tropical commercial catchment

  • Characteristics of greywater from different sources within households in a community in Durban, South Africa

    The reuse of greywater is steadily gaining importance in South Africa. Greywater contains pollutants that could have adverse effects on the environment and public health if the water is not treated before reuse. Successful implementation of any greywater treatment process depends largely on its characteristics in terms of the pollutant strength. This study investigated the physico-chemical ...
