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 ...

Comparative evaluation of conventional and microwave hydrothermal carbonization of human biowaste for value recovery
This paper compares conventional and microwave hydrothermal carbonization (HTC) of human biowaste (HBW) at 160 °C, 180 °C and 200 °C as a potential technology to recover valuable carbonaceous solid fuel char and organic-rich liquor. Also discussed are the influence of HTC heating methods and temperature on HBW processing conversion into solid fuel char, i.e. yield and post-HTC management, ...

Wastewater treatment in the dairy processing industry - recovering energy using anaerobic technology
Introduction The composition of wastewater from dairy processing plants makes it highly suitable for biological wastewater treatment processing. As well anaerobic biological treatment of the wastewater there is also the option of applying anaerobic biological processes. By applying anaerobic technology a large part of the organic load in the wastewater can be removed and converted into ...

Modified ADM1 for high-rate anaerobic co-digestion of thermally pre-treated brewery surplus yeast wastewater
Co-digestion of surplus yeast with brewery wastewater is a potentially economical method for recovering energy, in the form of biogas, from this difficult to dispose of by-product. In this work a modified version of the ADM1 (Anaerobic Digestion Model No. 1) was calibrated for an anaerobic digester fed with thermally pre-treated brewery yeast surplus wastewater. The model could predict ...

Recovering energy from biogas emission: the case of Mariana Mantovana landfill (Italy)
This paper deals with the analytic rating of the economic investment in an energy recovery plant for municipal waste, in relation to the estimate of its capability to exploit biogas production transformation, and sale of electricity production, and the Green Certificates. The approach entails the assessment of potential scenarios of biogas flare coming from its production forecasts, according to ...

Study of available exhaust gas heat recovery technologies for HD diesel engine applications
Diesel engines reject a considerable amount of energy to the ambience through the exhaust gas. Significant reduction of engine brake-specific fuel consumption (bsfc) could be attained by recovering a significant part of exhaust gas heat. Various techniques have been proposed in the past to recover exhaust energy: mechanical, electrical turbocompounding and Rankine Bottoming Cycles. In the present ...

GTI and the City of Tulare celebrate 25 years of converting waste to energy - case study
Energy conservation has always been extremely important to both the City of Tulare and the wastewater treatment facility. Since biogas can be used as fuel to generate electricity, the city wanted a means to reliably collect biogas from the BVF® reactor to recover the energy while also controlling odors and reducing greenhouse gas emissions. To address the City of Tulare’s needs, ...

Plasma gasification and vitrification of ash – conversion of ash into glass-like products and syngas
The Plasma Gasification and Vitrification of Ash (PGVA) system is a patented process that uses energy generated by plasma arcs along with the controlled addition of small amounts of air and steam to convert the organic portion of ash into a synthesis gas (gasification) and the inorganic portion into a glassy rock (vitrification). The vitrification of the ash’s inorganic portion ...

Ottawa Hospital, Ottawa Heart Institute, Ottawa, Ontario, Canada
Boiler Plant Application Objective The turnkey FLU-ACE waste heat recovery system was installed by Thermal Energy on four boiler exhausts from a power plant which produced a peak (winter) steam rate of 70,000 lbs/h. The system was designed to recover 10 mmBTU/h of otherwise wasted energy. The recovered heat is used to heat the the world-famous University of Ottawa Heart Institute Research ...

Energy from Waste (EfW)
To recover energy from waste is a necessary and useful part of the whole waste management process. Inciner8 have developed the first truly mobile waste to energy solution in their EfW range of equipment. Using new technology they have devised the optimal way to create energy from waste and make it useable for multiple applications ranging from disinfection, heating, washing or the generation of ...

Case study - Heat exchanger retrofit
Overview A manufacturer of insulation films for the electronics industry needed to evaluate the capabilities of four existing oxidizers that treated emissions from its coating lines. The company was concerned that, due to oxidizer deficiencies, it would not meet regulatory requirements. The oxidizers had been manufactured by two different companies. One of them was no longer in business; the ...

Wood briquettes packed full of energy
Konolt manages its energy output using RUF briquetting machinery Timber processors Konold are improving their energy balance with the help of their RUF briquetting machine. Wood waste is being pressed into briquettes to create a uniform combustible material. The heat they produce is then used for process heating and to heat their premises, with the residual heat being used to generate ...

Case study - Air-to-water heat exchanger reduces operating costs by $120,000 per year
OVERVIEW This pharmaceutical company had a 5,000 SCFM oxidizer that they were looking to relocate to another facility across the United States. The destruction rate efficiency and heat recovery expectation at the new location differed from the original design conditions at the current facility. ACTION An Anguil field service engineer went to site to inspect the unit. A report detailing the ...

Biogas recovery from a temperate climate covered anaerobic pond
New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...

Case study - Oxidizer energy recovery options
Overview The mainstream media today is full of allusions to energy awareness and conservation. Just as visible these days are media references to astronomical dollar figures that can boggle the mind. This article does not seek to break out of that mold, but rather to conform to it – as Oxidizer Stack Heat Recovery offers a tremendous opportunity for both energy conservation and energy ...

A STIEFEL project KVA Linthgebiet Niederurnen case study
The waste incineration plant KVA Linthgebiet is situated in Switzerland. The plant disposes of a total of 120’000 tons of waste each year from 240‘000 inhabitants in the surrounding area. Due to the thermal recovery, it produces annually 84 GWhour of electrical energy and therefore saves 250’000 litres of fuel oil by providing energy to a district heating system. Background and ...

Energy at Wastewater Treatment Plants - A Short Primer
On the topic of wastewater, most people are understandably of the “flush and forget” variety. But today’s wastewaster professionals recognize that in the long term, our approach to sewage treatment needs to be less about “processing” wastewater, and more about “recovery” of limited resources such as water and energy from the incoming waste. ...
