  • 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 ...

  • How is biodiesel produced?

    This article is the first in a series that will take a close look at alternative fuels production and source materials. Over the next several months, we will cover natural gas, propane, ethanol, hydrogen, and fuel cells. This month, we will focus on biodiesel. Methods for creating fuels from renewable biomass feedstocks have been used since the 1800s. Vegetable oils were used in diesel engines ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Combined Sanitary Sewer Overflows (SSO) - Performance Focus: Fats, Oil and Grease (FOG) Reductio Case Study

    In-PIpe Technology Company, Inc., drastically accelerates the natural degradation of fats, oil and grease (FOG) in the collection system, thereby removing blockages and occlusions from the pipe and significantly reducing the occurrence of FOG-related sewer overflows, as well as the requisite equipment and manpower required for the physical removal of these blockages. Since In-Pipe started ...

  • Case Study - The performance of the grease degrading bioproduct greasolux in the meat manufacturing factory and municipal WWTP

    Problem A municipal waste water treatment plant in one Baltic town continuously had problems with the fat, oil and grease (FOG) accumulation in the sewer lines, lift stations and waste water treatment plant, since the start up of a local meat processing facility. The highly polluted waste water directly impacted the treatment plant in the following ways: Increased grease ...

  • 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 ...

  • Respirometry study about the olive oil effects in the activated sludge process case study

    The problem of Oils in the Activated Sludge Process In many activated sludge plants excessive oils discharges can give rise to Nocardia foaming which causes major operational problems. While the bulk of the oils are removed in Dissolved Air Flotation (DAF) units or grease interceptors the remainder must be treated in the wastewater treatment system. But however, in case of high ...

  • Profile: Factors that influence properties of FOG deposits and their formation in sewer collection systems

    The quantification of the factors that may affect the formation of the fat, oil, and grease (FOG) deposits and their chemical and rheological properties were predominantly covered in the paper. The factors included the types of fats used in food service establishments (FSEs) and the types of calcium sources and environmental conditions (i.e. pH and temperature) in sewer systems. These factors are ...

  • Solvent choices for infrared testing of oil and grease in water

    Water is a very strong absorber in the mi d infrared (I R) regio n where o il is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels with mid IR, the water absorbs so much of the infrared energy that the signal becomes saturated ...
