Reuse options for coal fired power plant bottom ash and fly ash
Reviews in Environmental Science and Bio Technology, 2014Co-Authors: Madawala Liyanage Duminda Jayaranjan, Eric D Van Hullebusch, Ajit P. AnnachhatreAbstract:Reuse options for coal fly ash and coal bottom ash are reviewed in this paper. Although, significant quantities of coal fly ash and coal bottom ash are produced worldwide every year, less than 30 % of coal ash produced is Reused. Coal ash is mainly Reused in civil engineering applications such as road construction, embankments, construction materials, geo-polymer applications and in cement production. Other Potential Reuse options for coal ash include applications such as glass ceramics, water and wastewater treatment, agriculture as well as for making high value products (e.g. telescope mirrors, break-liners, fire proof products etc.). Considering that only a small fraction of coal ash is Reused, other Reuse options for commercial applications need to be explored.

Reuse of textile effluent treatment plant sludge in building materials
Waste Management, 2006Co-Authors: J Balasubramanian, P C Sabumon, John U Lazar, R IlangovanAbstract:This study examines the Potential Reuse of textile effluent treatment plant (ETP) sludge in building materials. The physico-chemical and engineering properties of a composite textile sludge sample from the southern part of India have been studied. The tests were conducted as per Bureau of Indian Standards (BIS) specification codes to evaluate the suitability of the sludge for structural and non-structural application by partial replacement of up to 30% of cement. The cement–sludge samples failed to meet the required strength for structural applications. The strength and other properties met the Bureau of Indian Standards for non-structural materials such as flooring tiles, solid and pavement blocks, and bricks. Results generally meet most ASTM standards for nonstructural materials, except that the sludge-amended bricks do not meet the Grade NW brick standard. It is concluded that the substitution of textile ETP sludge for cement, up to a maximum of 30%, may be possible in the manufacturing of non-structural building materials. Detailed leachability and economic feasibility studies need to be carried out as the next step of research. � 2005 Elsevier Ltd. All rights reserved.

Sanitation assessment of wastewater treated by stabilization ponds for Potential Reuse in agricultural irrigation sanitation assessment.
Water Environment Research, 2008Co-Authors: R. P. Pivelli, Maria Tereza Pepe Razzolini, Wanda Maria Risso Günther, Glavur Rogério Matté, Silvana Audrá Cutolo, Solange Martone-rocha, Francisca Alzira Dos Santos Peternella, M. C. O. Doria, Maria Helena MattéAbstract:Abstract Wastewater Reuse has become an important alternative to agricultural irrigation; on the other hand, it poses concern with regard to public health. Total coliform and Escherichia coli concentration, presence of helminth eggs and Salmonella, and physical-chemical parameters were evaluated in raw and treated wastewater. Chemical and biochemical oxygen demand removal efficiency was 74.6 and 77.9%, respectively. As for organic nitrogen, total phosphorus, and total suspended solids, total efficiency removal was 17.4, 12.5, and 32.9%, respectively. The average density of total coliforms and E. coli was 3.5 x 10(9) and 1.8 x 10(8) MPN/100 mL and 1.1 x 10(7) MPN/100 mL and 3.9 x 10(5) MPN/100 mL for raw and treated wastewater, respectively. Ascaris eggs were observed in 80.8% of the samples collected, and viable eggs in 42.3% of the samples. Salmonella was detected in 36.4% of the samples. The values observed in treated wastewater did not show the adequate bacteriological quality, as recommended by World Health Organization (Geneva, Switzerland). Therefore, additional measures should be taken to achieve an improved microbiological and parasitological quality.

OCCURRENCE OF Escherichia coli O157 IN RAW AND TREATED DOMESTIC SEWAGE FROM STABILIZATION PONDS WITH Potential Reuse IN AGRICULTURAL IRRIGATION
2002Co-Authors: Maria Tereza Pepe Razzolini, Paulo, Francisca Alzira Dos Santos, Maria Helena MattéAbstract:Treated domestic wastewater Reuse from stabilization ponds have been increasing importance lately as real alternative in agricultural irrigation. In Sao Paulo state (Brazil) where there are 195 these kind of treatment systems the Potential Reuse in agricultural irrigation is very significative. The goal of this study was investigate the occurrence of E. coli O157, an important pathogen, in treated sewage from stabilization ponds systems from Lins city (Sao Paulo state – Brazil) with Potential agricultural Reuse as a tool at the assessment these waters and provide information about E.coli O157 in environmental samples. The analytical method was qualitative using typical colonies at sorbitol Mc Conkey from bacterial growth at EC medium These colonies were confirmed by serological. The results showed E. coli O157 strains presence in 4% of the isolated strains (149 strains). It could be observed that researches with this approach are fundamental to minimize public health risks related to wastewater Reuse in agricultural irrigation.
