Olive mill waste water treatment

by EVALED  (Jun. 4, 2013)

The production of olive oil generates two kind of waste waters: RINSING WATERS: the quantity is subject to change. It can be re-circulated, after the settling to remove the solids, or discharged directly. SLUDGE: vegetation water with additional water, whose quantity is subject to change. In case of traditional oil mills, the hot additional water ...

Renewable Energy - A Key Solution to End Global Warming

by Vista Solar  (Jul. 7, 2014)

Scientists have spent years trying to find the causes of global warming leading to significant changes in the world’s climate. Their research shows that several factors have contributed to the rise of earth’s temperature and altering of natural cycles and actions. One key reason is excessive emission of greenhouse gases like, methane ...

Biogas in Asia

by Geotech  (Jul. 22, 2014)

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 ...

Meeting regulations and improving quality case study

by Sequoia Global, Inc.  (Sep. 5, 2014)

A UK-based waste oil collector was using emulsifiers and heat to drop water out of waste lube oils and fuels. The processed oil with 0.5-1.0% water was being filtered in a centrifuge. The company installed Sequoia’s efficient water evaporation equipment which produces oil with less than 0.1% water. As a result, the centrifuge works more ...

Using biogas for combined heat and power

by Clarke Energy  (Nov. 23, 2012)

An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs ...

Leveraging Standards in the Energy Resurgence

by ASTM International  (Aug. 29, 2014)

An Interview with Fred Walas, P.E., Fuels Technology Manager, Marathon Petroleum Company Marathon Petroleum’s Fred Walas talks about today’s energy developments, sustainability at his company’s refineries and the crucial role of standards in fuel production and quality control. As the energy spectrum shifts in the United States, ...

A study on the thermodynamic analysis of a cascaded latent heat storage system over the single storage tank system for diesel engine waste heat recovery

by Inderscience Publishers  (Nov. 9, 2012)

This article presents the comparison of performance of a cascaded Latent Heat Storage (LHS) system over the Single Storage Tank (SST) system for heat recovery from a diesel engine. The energy and exergy saved and efficiencies during the charging process are evaluated and reported using actual system data. The discharge process is analysed with a ...

Saving waste in the boiler house

by EBE Engineering Ltd.  (Apr. 16, 2013)

Burner technology has improved greatly in recent years. Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners ...

Removing Struvite from wastewater systems

by Scalewatcher North America Inc  (Jan. 27, 2014)

Named after Henrich Christian Gottfried Von Struve, who discovered the magnesium ammonium phosphate crystals in medieval sewer systems in Hamburg in 1845, struvite is a major problem for waste water treatment plants. The hard, crystalline deposit forms scale on lines and belts, in centrifuges and pumps.  It also clogs system pipes and other ...
