Grease waste and sewage sludge co-digestion enhancement by thermal hydrolysis: batch and fed-batch assays
Grease waste (GW) is an adequate substrate for sewage sludge co-digestion since, coming from a waste water treatment plant, it has a high methane potential (489 NmLCH4/gVSin); however, no synergistic effect takes place when co-digesting with 52%VS grease. Conversely, thermal hydrolysis (TH) improves the anaerobic digestion of GW (43% higher kinetics) and biological sludge ...

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 ...

Ultrasonic Waste and Sludge Treatment
Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

Waste treatment Wernsing Anaerobic Digestion Plant (Germany)
Wernsing biogas plant Addrup The Wernsing biogas plant was one of the first biogas weser-ems plants to treat waste from food industry since its commission in 2001. Up to 200 tonnes of white cabbage and potatoes waste are used as main input material per day. In addition to the biogas plant, the facilities owned by the Wernsing group include a waste water treatment plant to treat the sewage ...

Municipal waste water treatment plant case study
A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

Technical and economic analysis of real anaerobic digester centrate by means of partial nitrification and sustainable heterotrophic denitrification
The reliability of partial nitrification coupled with heterotrophic denitrification for the treatment of real anaerobic digester centrate produced in a wastewater treatment plant was technically and economically assessed in two sequencing batch reactors. Removal efficiencies above 90% were consistently achieved at N-ammonium loads above 1.2 g N L−1 d−1. Ethanol, affluent ...

Anaerobic digestion of aliphatic polyesters
Anaerobic processes for the treatment of plastic materials waste represent versatile and effective approach in environmental protection and solid waste management. In this work, anaerobic biodegradability of model aliphatic polyesters, poly(L-lactic acid) (PLA), and poly(ɛ-caprolactone) (PCL), in the form of powder and melt-pressed films with varying molar mass, was studied. Biogas production ...

Project Government building the Hague - Case Study
For the Dutch government building "Nieuwe Rijkskantoor" located at Rijnstraat 8, The Hague, Landustrie realized a decentralised water treatment plant. This new accommodation for approx. 6000 civil servants from a number of government ministries is equipped to process the wastewater and recover energy and nutrients. The existing waste streams from the office are treated in the building; the ...

Newport WWTP Newport, WA
In 2003 the city of Newport began a study of upgrading the city’s waste water treatment plant. Plant flows were increasing and the city wanted to process sewage from septage haulers handling recreational development in the area. Esvelt Environmental Engineering Company was selected to do the study and facility design. One of the first decisions made was rather than expand aeration basins, ...

Effects of the incorporation of drinking water sludge on the anaerobic digestion of domestic wastewater sludge for methane production
Water purification and wastewater treatment generate sludge, which must be adequately handled to prevent detrimental effects to the environment and public health. In this study, we examined the influence of the application of settled sludge from a drinking water treatment plant (SDWTP) on the anaerobic digestion (AD) of the thickened primary sludge from a municipal wastewater treatment plant ...

Verification of an alternative sludge treatment process for pathogen reduction at two wastewater treatment plants in Victoria, Australia
At South East Water wastewater treatment plants (WwTPs) in Victoria, Australia, biosolids are stockpiled for three years in compliance with the State guidelines to achieve the highest pathogen reduction grade (T1), suitable for unrestricted use in agriculture and landscaping. However, extended stockpiling is costly, may increase odour nuisance and greenhouse gas emissions, and reduces the ...

Working with energy and mass balances: a conceptual framework to understand the limits of municipal wastewater treatment
At present all municipal waste water treatment plants (WWTPs) are energy consumers. Electrical energy requirements for oxygen transfer are large in secondary biological systems. Nevertheless, from a thermodynamic point of view chemical oxygen demand (COD) is an energy source. Combustion of every kilogram of COD releases 3.86 kWh of energy. In this manuscript some measures are presented, from a ...
