  • A simulation of the fate of nitrogen in an on-site wastewater treatment system

    An experiment to study and to build a mathematical model to reproduce the behavior of nitrogen in a residential wastewater treatment process was performed. A pilot unit receiving grey and black water was used. The pilot consisted in a septic tank followed by a fixed-film, partly aerated bioreactor with effluent recirculation operated under two different scenarios: normal operating conditions and ...

  • Effectiveness of Alternative On-Site Wastewater Treatment Technologies

    ABSTRACT New York City’s drinking water supply is threatened by the potential development of the Catskill/Delaware watershed. The effectiveness of alternative on-site wastewater treatment systems in this drinking water supply watershed is being evaluated during the course of a oneyear field study. Twenty-four on-site systems were designed and installed for individual sites throughout the ...

  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • Water treatment in Brazil

    The challenge Many factories in Brazil do not dispose their sewerage in a professional way. Only big enterprises use facilities to treat their industrial waste water, whereas numerous small and medium-sized enterprises convey their sewerage flow into rivers and brooks or pit drainages. This results in a significant environmental burden and endangers the health of the population. ...

  • The Daytona Beach Ralph Brennan Water Treatment Plant Finds On-Site Generation to be a Safe and Economical Solution for Water Disinfection

     ABSTRACT For many years the use of gaseous chlorine at water treatment plants has been an effective and widely used method of disinfection. It is still the most commonly used disinfectant treatment in water treatment plants in the United States. In recent years however, the safety of chlorine gas has come under increased scrutiny. The side effects to chlorine gas exposure at low levels ...

  • Institutional trajectory for diffusing on-site wastewater treatment in urban China

    Urban water scarcity has been an issue for a long time in China while water pollution has attracted more and more attention over the last two decades. Recently, on-site wastewater treatment (OST) has been proposed as a meaningful alternative to deal with both water pollution and water scarcity in cities in a more sustainable way. However, the diffusion of such an OST system is still slow and ...

  • The East-Sullivan Mine Site: Merging Prevention and Treatment of Acid Mine Drainage

    At East Sullivan, an innovative treatment of acid effluents is based on the sulphate reduction via the recirculation of water discharging around the impoundment through the organic cover. Data show that despite acid feeds down to pH 2.5, groundwater’s pH near the dispersal zone is maintained above 6. Alkalinity decreases during the recirculation, but is back up to 800 mg/L and more the following ...
