  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • Scale-up of the MIEX® DOC Process for Full Scale Water Treatment Plants

    The MIEX® DOC Process is a new process developed by Orica Watercare, South Australian Water Corporation and the CSIRO for the removal of dissolved organic carbon (DOC) from drinking water. Results from scale up of the process to a 170m3/day pilot plant have been reported previously (Nguyen, 1997). The process has now been successfully scaled up and trialed on a 1000m3/day pilot plant located at ...

  • Large scale diamond electrodes for industrial water treatment

    The DiaCell® technology, based on boron-doped diamond films on Silicon substrate (BDD/Si), is a new candidate in the electrochemical water treatment market. Water disinfection and also wastewater treatment and recycling are the main targeted applications [1]. While most of the private applications such as pool water disinfection [2] require electrode surfaces in the range of 0.1 m2 per unit, the ...


  • Pilot-scale studies on the treatment of tannery effluents by electroflotation

    A pilot-scale electroflotation system with a treatment capacity of 0.8 m³ per hour has been designed and built. The system is equipped with a conditioning tank, a rectifier, flow meters, an energy meter and pumps. Iron, aluminium and titanium coated with oxides of tantalum, ruthenium and iridium were used as electrodes. The system was installed within the premises of the Common Effluent Treatment ...

  • Anaerobic treatment of food waste in pilot scale

    For this work, a pilot scale anaerobic digester was used to assess the treatability of food waste from a canteen. The digester was operated for 720 days, and its efficiency in removing organic matter and suspended solids as well as producing biogas were assessed. At the beginning of operation, the digester failed and alkalinity buffering was required until stabilization. A maximum chemical ...

  • Energy Recovery in Urban Wastewater Treatment on Global Scale

    ABSTRACT The lack of proper wastewater treatment results in production of CO2 and CH4 without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO2 and CH4 emissions associated with wastewater discharges could reach the equivalent of 3.13·105 tCO2·d-1 in 2025, with ...

  • Small-Scale Biosolids Composting

    Cambridge, Ohio retrofitted a portion of its vacuum assisted drying beds into a covered composting facility, processing about 300 dry tons/year of biosolids and wood chips. Like many small communities in an agricultural area, the City of Cambridge, Ohio (pop. 14,000) managed biosolids generated by its 2.25 mgd Water Pollution Control Center (WPCC) via land application on farm fields. “Then ...

  • Successful Pilot Test Results in Full-Scale Treatment of Large BTEX Plume

    CASE SUMMARYRefueling Station – Algonquin, IL Leaking underground storage tanks at a refueling station resulted in a benzene, toluene, ethylbenzene and xylene (BTEX) plume in the underlying sand/gravel aquifer. The plume covered 1-acre and extended 390 feet downgradient from the source area, with a total BTEX concentration exceeding 24,000 parts per billion (ppb). In an ...

  • Treatment of Sludge Return Liquors: Experiences from the Operation of Full-Scale Plants

    ABSTRACTMore stringent effluent criteria with regard to nitrogen call for improved nutrient removal techniques in wastewater treatment plants (WWTPs). Besides optimisation of the liquid treatment train of the plants, over the last years, attention has increasinly centred on the problem of return flows from sludge treatment. Depending on sludge handling and treatment, some 15 to 25 % of the ...

  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...

  • Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment

    Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these two ...

  • Treatment of winery wastewater in a full-scale fixed bed biofilm reactor

    ABSTRACTThe treatment of winery wastewater was performed at full-scale applying a two-stage fixed bed biofilm reactor (FBBR) system for the discharge in the sewerage. The results of the first year of operation at the full-scale plant are presented. Values of removed organic loads and effluent concentrations were interpreted on the basis of the COD fractionation of influent wastewater assessed ...

  • Effect of oxygen deprivation on treatment processes in a full-scale drinking water biofilter

    Dissolved oxygen is critical for proper operation of waterworks that utilize anaerobic groundwater and rely on biofilters to remove iron, manganese and ammonium. In these biofilters, planned or inadvertent oxygen deprivation may occur for a variety of reasons. The water quality effects of oxygen deprivation on the function of drinking water biofilters, however, have not previously been reported. ...
