This book was released on 2013 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to verify the status of the application of Ultrasonic Membrane Anaerobic System (UMAS) in wastewater treatment, efficiency of UMAS in methane production and kinetic parameters in sewage sludge on methane production from sewage sludge by using UMAS. UMAS consist of Ultrafiltration membrane for solid-liquid separation with 1.5 - 2.0 bar of operational pressure. The wastewater has been extensively analyzed for six parameters which are pH value, biochemical oxygen demand (BOD), chemical oxygen demand (COD), volatile fatty acids (VFA), total suspended solid (TSS) and volatile suspended solid (VSS). The reactor is operated at ambient temperature and wrapped with aluminum foil to avoid direct sunlight, which can affect the bacteria. The raw sewage sludge was obtained from Indah Water Air Putih, Kuantan. Sewage sludge is tested using jar test for the chemical requirements to remove small particles in the waste water. The digester operates 5 hours every 4 days for 12 days. The product that been produce contained carbon dioxide and methane gas. Both gases are collected into a syringe that connected with two rubber tube and a glass tube. Compare to aerobic digestion which is expensive method since it used oxygen and anaerobic digestion that requires larger area and slower process, UMAS was being innovated and offer great advantages. Carbon dioxide is removed by manipulated the syringe using 10 ml of sodium hydroxide. Methane gas is measured once every four days. This treatment showed the best solution to treat waste water such as reduction of COD contents and increased percentage of methane gas. Thus, make UMAS is a good alternative for treating wastewater.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study proposes a new approach for integrated technology of ultrasonic and membrane for a palm oil mill effluent treatment. This study evaluated the performance of the new design of ultrasonic membrane anaerobic system (UMAS) when a palm oil mill effluent (POME) introduces this approach. To fit kinetic study, six steady states were investigated and the results have shown that the mixed liquor volatile suspended solids (MLVSSs) range from 10,400 to 17,350 mg/l while the mixed liquor suspended solids (MLSSs) range from 13,800 to 22,600 mg/l. Three kinetic models of Monod, Contois, and Chen and Hashimoto were used to evaluate the integrated system at organic loading rates ranging from 1 to 15 kg COD/m3/day. The percentage efficiency of COD removal was from 92.8 to 98.3%, and hydraulic retention time (HRT) was from 500.8 to 8.6 days. The influent COD concentrations of the POME ranged from 70,400 to 90,200 mg/l.The integrated technology of UMAS is a more attractive one as it avoids membrane fouling problems.

This book was released on 2014 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sugarcane industry is one of the most important industries in many developing countries. However, sugarcane industry produces significant amount of wastes mainly in the form of liquid wastes. In present study, biological treatment with membrane technology and ultrasound effect was carried out to treat sugarcane wastewater. The main objective of this study is to make an overall comparison between membrane anaerobic system (MAS) and ultrasonic membrane anaerobic system (UMAS) in treating sugarcane waste. Raw sugarcane wastewater was operated in a membrane anaerobic reactor for 5 hours for 7 continuous days. After 5 hours of operation, the permeate (filtrate) from the reactor was collected and tested for BOD, COD, TSS and VSS. The gas produced was collected using designated syringe. The experiment was repeated with 10 kHz of ultrasound frequency devise attached to the membrane to investigate the effect of ultrasonic wave towards the process. From this study, for COD and BOD, MAS has achieved 86% removal efficiency and UMAS achieved 96% removal. For TSS, MAS obtained 81% removal efficiency but UMAS attained 100% removal which shows UMAS has removed all the detectable suspended solids from the wastewater. The same trend goes for VSS removal efficiency. MAS produced 1400mL of permeate and UMAS produced 2346mL of permeate. This huge difference in volume was due to the fouling which blocks the membrane pores. For biogas production, 68% and 77% of methane gas have been produced during MAS and UMAS treatments respectively. From these results, it proves that UMAS has prevented fouling and it is more proficient than MAS as it produced permeate which meet the discharge limit fixed by Malaysia Department of Environmental (DOE).

This book was released on 2013-02-27 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The level of surface water quality protection is variable around the world in large part due to the relative effectiveness of environmental regulation and the degree to which science influences the regulatory process. In the United States, at the federal level, the Total Maximum Daily Load (TMDL) has been an effective policy and water quality management tool for dealing with both point source and non-point source pollution. The TMDL provides a rational framework for estimating the assimilative capacity of the receiving water body for certain contaminants and applying factors of safety and incorporating acceptable levels of water quality criteria violation - provided the local stakeholders have a say in the decision making process. This collection of articles from around the world are good examples of the application of sound scientific principles to solve pressing water quality problems.

This book was released on 2012-12-06 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many significant microbiological, biochemical and technological advances made in the understanding and implementation of anaerobic digestion processes with respect to industrial and domestic wastewater treatment. Elucida tion of the mechanisms of anaerobic degradation has permitted a greater control over the biological parameters of waste conversion and the technical advances achieved have reduced the time and land area requirements and increased the cost-effectiveness and efficiency of the various processes presently in use. By product recovery in the form of utilisable methane gas has become increasingly feasible, while the development of new and superior anaerobic reactor designs with increased tolerance to toxic and shock loadings of concentrated effiuents has established a potential for treating many extremely recalcitrant industrial wastestreams. The major anaerobic bioreactor systems and their applications and limitations are examined here, together with microbiological and biochemical aspects of anaerobic wastewater treatment processes.
