  • Energy Recovery System - Case Study

    Addfield collaborated with an energy recovery company and one of the UK’s largest landscaping and recycling companies to produce the innovative idea of creating energy from waste. Some things cannot be recycled so instead of sending these to a landfill they are incinerated and reused to create hot water and electricity. This is then used to heat and power the garden centre whilst ...

  • Energy recovery in the water industry using micro-hydropower: an opportunity to improve sustainability

    The water industry as a whole consumes a considerable amount of energy in the treatment and distribution of water and wastewater. Like all sectors of society today, the industry is focusing efforts on reducing its CO2 emissions and improving the sustainability of its systems and practices. One way of achieving this is through the use of micro-hydropower (MHP) installations in water ...

  • Butanol production from the effluent of hydrogen fermentation

    The purpose of the study was to recover butanol from the effluent of the hydrogen-producing bioreactor containing acetate, butyrate, and carbohydrate. The butanol production by Clostridium beijerinckii NRRL B592 was evaluated under both unsterilized and sterilized conditions for examining the potential of butanol production for the practical application. Sucrose of 10 g/L and butyrate of 2 g/L ...

  • Regenerative snubber for UPS inverter

    An uninterrupted power supply (UPS) is used to provide electrical power to a load during an emergency situation in which the main utility power is not available. UPS topologies are well known. The inverter plays the most important role as an element in the UPS system. Usually, pulse width modulated inverters with voltage control and waveform shaping are used in UPS. This paper proposes an ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • Energy recovery from gas compressors

    With the development of natural gas recompression plants, linked to the opening of the global gas market, which means increased exchanges and transportation between production and consumption areas, the number of energy recovery projects on this type of installation is ...
