DMT to inject in Cadent`s LTS grid using Hexel One Plastic Pipe
The production of biogas through anaerobic digestion and grid injection isn’t new to the UK with over 100 sites now injecting biomethane into the local gas grids. Since DMT’s first commercial biogas upgrading to biomethane plant back in 2012 the biogas industry has developed considerably. And with every changing industry, DMT has adapted to these changes in the industry and progressed ...

A fuzzy rule–based approach for modelling effects of bench–scale microwave pre–treatment on solubilisation and anaerobic digestion of secondary sludge
Fuzzy rule–based models were proposed in order to predict the effect of microwave pretreatment on the waste activated sludge (WAS) solubility and anaerobic digestibility or biogas production. The developed models were trained and validated using the experimental data from two separate multilevel factorial designs, containing 24 solubilisation and 54 biogas production runs from batch mesophilic ...

The effect of mixing conditions on anaerobic digester performance
The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

Coupling ASM3 and ADM1 for wastewater treatment process optimisation and biogas production in a developing country: case-study Surat, India
The overall performance of the Anjana wastewater treatment plant (WWTP) located in Surat, India, was assessed by coupling the Activated Sludge Model No. 3 (ASM3) and the Anaerobic Digestion Model No. 1 (ADM1). Guidelines developed by the Dutch Foundation for Applied Water Research (STOWA) were successfully applied for the determination of wastewater characteristics. Concerning the fractionation ...

Biogas and Anaerobic Digestion in Relation to CH4 Methane Monitoring
The use of biogas as a renewable energy source currently accounts for 10 % of global primary energy consumption1 and is often heralded as the perfect example of the ‘circular economy’ – where waste products can be reused to generate energy for other processes in a self-perpetuating cycle.2 Biogas consists of the mixture of gases produced by the breakdown of organic matter by ...

Project - Södertörn, Sweden - Case Study
Scandinavian Biogas plans to increase production capacity at Scandinavian Biogas Södertörn from the current 80 to 120 GWh. The expansion will be completed by the end of 2021 and will include both an increased gas production capacity and a liquefaction plant where the produced gas is converted into liquid biogas (LBG). In connection with the development, a number of new process ...

Monitoring sewage sludge AD for Southern Water - Case Study
To check sludge AD, Southern Water uses portable biogas analysers specially developed for AD biogas and based on proven methane and associated gas analysis equipment from Geotech. Southern Water has an important routine; every single day it checks the health of its sewage sludge anaerobic digesters on eighteen sites across Hampshire, IoW, Sussex and Kent. There, each day Southern Water treats ...

Treatment of Biogas Produced in Anaerobic Reactors for Domestic Wastewater: Odor Control and Energy/Resource Recovery
Anaerobic municipal wastewater treatment in developing countries has important potential applications considering their huge lack of sanitation infrastructure and their advantageous climatic conditions. At present, among the obstacles that this technology encounters, odor control and biogas utilization or disposal should be properly addressed. In fact, in most of small and medium size anaerobic ...

Assessing the treatment costs and the fertilizing value of the output products in digestate treatment systems
The objective of this paper was to advance towards finding sustainable solutions to deal with biogas digestate and contribute to faster development of the market for digestate treatment products. The study compares digestate treatment costs through four different treatment plants, estimates the potential fertilizing and humus value (PFHV) of the derived products and allocates the cash flows to ...

Development and application of biogas project for domestic sewage treatment in rural China: opportunities and challenges
The biogas project for domestic sewage treatment (BPDST) is considered a promising facility for wastewater management in rural areas of China. This paper explores previous experimental works, cost analysis, and BPDST structure and design based on Chinese literature. Opportunities for developing decentralized or neighborhood-based BPDSTs include fulfilling Millennium Development Goals (MDGs) ...

Optimising biogas generation in the UK and Germany - Case Study
Methane makes money. It generates energy revenues, carbon credits and is part of bio-treatment sludge processing. In most of the world it has only just begun. Measuring what we are doing and being responsible with this potentially damaging greenhouse gas makes good sense. With gas production for revenue, measurement is essential. While landfill gas analysis has been required for compliance with ...

Biogas in Asia
The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM). The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia particularly hard. ...

Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water
Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other liquids ...

The Anaerobic Digestion of Bio-Waste in Developing Countries
The anaerobic digestion process is typically used as a means of waste disposal or energy production. Anaerobic digestion of bio-waste in developing countries is extremely beneficial as it doesn’t just generate clean and safe energy, it also contributes towards other economic development issues and has considerable environmental benefits. In this article we will explore the many benefits of the ...

Unmanned remote and wireless CDM monitoring case study
Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...
