  • Get More Juice Out of that Lemon: EBMUD’s Search for Energy in Wastewater

    Municipal wastewater treatment plants are increasingly interested in waste-to-energy technologies as a way to reduce operating costs. The East Bay Municipal Utility District (EBMUD) identified and evaluated a number of waste-to-energy technologies that had potential for application at its Main Wastewater Treatment Plant (MWWTP) in Oakland, California. These technologies included conventional ...

  • Modeling fats, oil and grease deposit formation and accumulation in sewer collection systems

    Fats, oil and grease (FOG) deposits in sewer systems are responsible for approximately 25% of all annual line blockages in the United States and lead to the release of 3–10 million gallons of untreated wastewater to the surrounding environment. Considerable effort has been made to maintain the conveyance of wastewater by cleaning pipes that have a significant FOG deposit accumulation. Changes ...

  • Advanced pretreatment enables MBBR treatment of high strength candy manufacturing wastewater

    Abstract Bimbo – Ricolino candy manufacturing plant in Mexico City was discharging wastewater with high amount of fats oil and grease and dissolved sugars. Local regulatory agency requested that suspended solids, oil and grease and dissolved BOD be almost completely removed prior to discharge to municipal plant. The available real estate in Mexico City was very limited. A multistep ...

  • Understanding the spatial formation and accumulation of fats, oils and grease deposits in the sewer collection system

    Sanitary sewer overflows are caused by the accumulation of insoluble calcium salts of fatty acids, which are formed by the reaction between fats, oils and grease (FOG) and calcium found in wastewaters. Different sewer structural configurations (i.e., manholes, pipes, wet wells), which vary spatially, along with other obstructions (roots intrusion) and pipe deformations (pipe sags), may influence ...

  • Missouri city wastewater treatment plant case study

    Project Summary Missouri City selected In-Pipe Technology, Inc. to provide a collection system bioaugmentation program reduce influent load, energy costs and sludge production at the wastewater treatment plant (WWTP). The program is also designed to control fats, oil and grease (FOG) accumulation and odor in the collection system. In-Pipe Treatment Strategy ...

  • Industrial Laundry

    Problem: For many years industrial laundries discharged their effluent into the local sanitation plant without any restrictions. Now, when applying for a new discharge permit, the laundries are required to meet the new guidelines established by the EPA These requirements are normally as follows: 100 PPM for fats, oils and greases; and 250 PPM for total suspended solids. Some ...

  • A critical review of experimental and predicted methane generation from anaerobic codigestion

    Anaerobic digestion is increasingly being considered as a treatment option for an extensive range of waste biomass, due to the potential for energy recovery, in the form of methane production, and lower sludge volumes relative to aerobic treatment processes. Furthermore, when two substrates are codigested (i.e. digested together), added benefits are foreseeable, such as increased methane ...

  • CH#1138 - Anaerobic Digesters

    Waste Type: Fats, oils and grease (FOG) in Anaerobic Digesters Problem: FOG waste poses a challenge for most municipal wastewater collection systems and treatment plants. Although fats, oils and grease will biodegrade in an anaerobic digester, high concentrations will tend to 'mat' on the sludge surface, lowering digestion efficiency. This Midwestern municipal facility was no different. The 1.5 ...

  • Fat, oil and grease waste from municipal wastewater: characterization, activation and sustainable conversion into biofuel

    Fat, oil and grease (FOG) recovered by the oil/water separator of a wastewater treatment plant (WWTP) were sampled, characterized, activated and converted into biofuel. Free acids (50–55%) and fatty soaps (26–32%) not only composed the main components, but they were also easily separable from the starting waste. The respective free fatty acid profiles were ...

  • Grease trap treatment in a meat plant

    Meat plants tend to be major producers of fats and grease and this present problems in the wastewater infrastructure as it is not soluble in water. This leads to build up in drains and grease traps and the traditional approach to disposal is to physically remove it and ship it off site for licensed disposal. A new approach is to use bioaugmentation to physically degrade the grease so that it ...

  • Treatment of poultry slaughterhouse wastewater using a static granular bed reactor (SGBR) coupled with ultrafiltration (UF) membrane system

    The South African poultry industry has grown exponentially in recent years due to an increased demand for their products. As a result, poultry plants consume large volumes of high quality water to ensure that hygienically safe poultry products are produced. Furthermore, poultry industries generate high strength wastewater, which can be treated successfully at low cost using anaerobic ...
