Anaerobic co-digestion of winery waste and waste activated sludge: assessment of process feasibility
In this study the anaerobic co-digestion of wine lees together with waste activated sludge in mesophilic and thermophilic conditions was tested at pilot scale. Three organic loading rates (OLRs 2.8, 3.3 and 4.5 kgCOD/m3d) and hydraulic retention times (HRTs 21, 19 and 16 days) were applied to the reactors, in order to evaluate the best operational conditions for the maximization of the biogas ...

Pilot-Scale Biofilter Test for Treating Zimpro Odors
The thermal sludge conditioning process of U.S. Filter/Zimpro Corporation, Rothschild, Wisconsin (Zimpro process) is primarily used to improve dewatering characteristics of the waste sludge. The process entails a partial breakdown through oxidation and hydrolysis of complex, high molecular weight organic compounds, such as, proteins, fibers, carbohydrates, and fats. The partial breakdown of ...

Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)
The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in order ...

How to deal with oil refinery sludge?
Refinery sludge refers to a mixture of oil, water and solids. It is generally produced in the process of oil extraction, transportation and refining. It contains crude oil or refined oil mixed with sediment or other substances. Among them, the effective oil cannot be directly separated and recovered, which will have an impact on environmental resources and pollute soil and water sources. ...

Wyeth - Case Study
Paddle Dryer turns waste into income for food processing plant. A northeast food processor turns its activated biological sludge waste from its manufacturing process into income by recycling the waste as an ingredient for organic fertilizer. When the state banned landfilling of the biological waste, a study was conducted that showed the waste contained enough nutrients to be considered a ...

Membrane thickening aerobic digestion processes
Sludge management accounts for approximately 60% of the total wastewater treatment plant expenditure and laws for sludge disposal are becoming increasingly stringent, therefore much consideration is required when designing a solids handling process. A membrane thickening aerobic digestion process integrates a controlled aerobic digestion process with pre-thickening waste activated sludge ...

Enhancing dewaterability of waste activated sludge by combined oxidative conditioning process with zero-valent iron and peroxymonosulfate
The enhancement of sludge dewaterability is of great importance for facilitating the sludge disposal during the operation of wastewater treatment plants. In this study, a novel oxidative conditioning approach was applied to enhance the dewaterability of waste activated sludge by the combination of zero-valent iron (ZVI) and peroxymonosulfate (PMS). It was found that the dewaterability of ...

Sustainable cost reductions: biogas from liquid wastes - Case Study
Generate energy instead of consuming it: treating liquid wastes and wastewater on a communal basis to generate biogas is an interesting alternative to conventional wastewater treatment and disposal for dairies. This is becoming a serious consideration for the future for milk producers given the globally increasing challenges arising from wastewater regulations or CO2 guidelines. More and more ...

What are the parameters of an extended-aeration activated-sludge system?
The activated sludge process is the most widely used biological water and wastewater treatment. As is well known, by its means, suspended-growth microorganisms are applied to breakdown wastes. Aeration, the mixing of air and a liquid, is the means used to speed the reactions involved. Aeration methods include spraying the liquid into the air; diffusing air into the liquid or agitating the liquid ...

What Makes GWT Advanced Treatment Technologies Different than Others
Advanced oxidation systems can treat water from a wide range of sources. All kinds of industries produce pollutants that conventional treatment systems cannot typical treat; this requires advanced treatment technologies. If those pollutants are not treated, they typically end up in water sources that are used for drinking water. If conventional drinking water treatment systems cannot treat & ...

Regarding on-site sludge digestion issues
As those who manage and/or operate waste treatment facilities of one sort or another, at the end of the process all are faced with that age old question – What now? How do we get rid of the finished “by-products”? We have several options among which are deep-well injection, holding and polishing ponds, or discharge into an existing body of water be it a stream, lake, or even the ...
