Research ArticleOpen accessPhrase in the titleReuse Water Treatment Sludge for Hollow Concrete Block ManufactureThaniya KaosolProblem statement: This research reuses the water treatment sludge from a water treatment plant to make hollow concrete blocks. The main objectives are to increase the value of the water treatment sludge from a water treatment plant and to make a sustainable and profitable disposal alternative for the water treatment sludge. Attempts were made to utilize the water treatment sludge … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 10,427 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleValorization of Drinking Water Treatment Sludges as Raw Materials to Produce Concrete and MortarR.M. Ramirez Zamora, O. Ceron Alfaro, N. Cabirol et al.The purpose of this work was to assess the technical feasibility to valorize sludges, generated and stored at the Los Berros drinking water facility (PPLB), as raw material to produce building products (mortar and concrete) for the construction industry. The experimental study was divided into three stages: 1) sampling and characterization of PPLB sludges to determine their potential as raw … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Composted Animal Manure as Fertilizer on Productivity of Azolla Pinnata Grown in Earthen PondsRistianto Utomo, Cuk Tri Noviandi, Nafiatul Umami, Adhitya PermadiAzolla pinnata contains a high nutritional value with a high protein content of 25%, so it can be used as an alternative to animal feed. The low production of Azolla is caused by the suboptimal use of fertilizers. This study aims were to determine the type of manure (composted manure from poultry, goats, and rabbit) which was the most optimal … …OnLine Journal of Biological Sciences, Vol. 19, Issue 4 · 9 Nov 2019 · 11,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Pressure, Water Depth and Water Flow Rate on Oxygen Saturation Level in Activated Sludge ProcessNabil N. Atta, Amro A. Elbaz, Alhassan H. SakrProblem statement: The role of aeration in activated sludge process is to provide oxygen to microorganisms as they assimilate the organic carbon compounds and digest a portion of them to carbon dioxide and water, sulfate and nitrate compounds. The water aeration equipment used in this process consumes as much as 60-80% of total power requirements in modern wastewater treatment plants. … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 21 Dec 2011 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaugmentative Approaches for Dairy Wastewater TreatmentIrina Schneider, Yana TopalovaProblem statement: The achievement of a good ecological status of water receivers after discharge of waste or partially treated water from dairy industry requires harmonic interaction between water treatment technology and self-purification processes. Approach: The present research included two modules. First: an anaerobic treatment process for dairy wastewater in broadly spread sequencing batch bioreactor with fixed biomass was studied. As … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 13 Dec 2010 · 8,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Development in Biological Process for Wastewater Treatment to Produce Renewable FuelKadhum M. Shabeeb, Khalid A. Sukkar, Rana A. Azeez et al.Problem statement: Hydrogen is a clean energy source. Bio-conversion of biomass to generate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, in wastewater. No data available on hydrogen yielded from wastewater using inoculum extracted from Iraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrate concentration, initial pH and process temperature on biohydrogen production … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Potential of Extended Aeration System for Sago Effluent TreatmentWahi Abd Rashid, Hamdan Musa, Wong Sing King, Kopli BujangProblem statement: Sago effluent contains large amount of organic material which has a potential to cause water pollution. In order to reduce this problem, an experiment was conducted to remove organic material from sago effluent using lab scale of Extended Aeration (EA) system. Approach: The EA system consisted of the combination of physical and biological treatment unit. For Physical Treatment … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,346 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring the Reuse Potential of Chemical Sludge from Textile Wastewater Treatment Plants in India-A Hazardous WasteHema Patel, Suneel PandeyProblem statement: This study was conducted to explore the reuse potential of the chemical sludge (considered as hazardous waste as per Indian Government Hazardous Waste Management Rules) generated from combined effluent treatment in textile clusters. These textile clusters mainly cover the cotton dyeing and printing operations. Approach: Therefore, treatability studies of chemical sludge were conducted using solidification/stabilization treatment to examine … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,539 accessesView PDFCite
