Aminuddin Muhamad Baki and four other young researchers, supervised by Professor Suhaimi Abdul Talib, of UiTM, found that having more organic content in sludge will generate more methane. Biogas composed of methane and carbon dioxide is a by-product of anaerobic bacterial decomposition of organic waste.
The organic waste content of municipal garbage and sewage means that they are important sources for biogas production. The methane content in biogas enables it to be used as engine fuel as well as enabling it to be converted into heat and electricity. An experimental study was completed that examined the relationship between the organic content of sludge and methane generation as the sludge progressed through mesophilic anaerobic digestion.
This study examined the organic content in sewage, represented by Biological Oxygen Demand (BOD) and Total Suspended Solid (TSS), in order to: (a) quantify the biogas and methane generation from sewage sludge; (b) determine the relationship between organic content and volume of methane; and (c) determine the pressure of biogas and the relationship between sludge volume and volume of biogas. It was found that there is potential for methane generation during anaerobic digestion even with a small volume of sludge.
The quality of sludge for methane generation is subject to the characteristics of the sludge. The organic content represented by BOD and TSS was measured in accordance to APHA standard methods (1998). Tests were conducted on wastewater from two treatment plants: the College of Mawar, UiTM, and IWK WWTP Section 7, Shah Alam. It was found that higher organic content in sewage sludge produced a higher volume of methane.Contacts:

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
