Evaluation of COD and BOD5 Removal Efficiency by Combined Treatment Aerobic-Anaerobic (AO) on Sewage of Metal Industries
Shortage of water resources and renewable per capita in last 30 years is put Iran on crisis threshold. Wastewater reuse is one of the battle solutions for water shortage and prevents wastewater depletion and environmental pollution. Thus, a pilot scale experiment was carried out to evaluate an integrated anaerobic/aerobic treatment for removal of BOD5 and COD, also to reduction of hydraulic ret...
متن کاملSwine waste treatment by self-heating aerobic thermophilic bioreactors.
Pig manure represents a very high-strength wastewater that is well suited for a self-heating aerobic thermophilic treatment. Here we report the use of 59-L Aerobic Thermophilic Sequencing Batch Reactors (AT-SBR) to study the treatment of pig manure with a HRT of 6 days. Temperatures up to 75 degrees C were reached without external heating by using Venturi-type aerators but these conditions were...
متن کاملanaerobic treatment by uasb reactor and aerobic biodegradability test of cutting oil sewage
introduction water is consumed in almost all industries. consequently the used water is turning to a waste that usually should be treated to meet the regulated standard level prior to reuse or discharge into the environment. cutting oil wastewater is an emulsion normally comprised of1-10% oil and the remainder water. the main functions of this oil in industry are lubrication, friction reduction...
متن کاملMunicipal Sewage Sludge Drying Treatment by an Composite Modifier
A sludge composite modifier SCM which comprises a mixture of three cementitious components was proposed for sludge drying and stabilization. Effect of SCM components on sludge moisture content was analyzed using uniform design and the optimum composition of SCM was determined by computer-aided modeling and optimization. To compare the drying effect of SCM, quicklime, and Portland cement, the ef...
متن کاملStudies on an autolytic substance produced by an aerobic sporeforming bacterium.
The capacity of many "surface-active" materials to cause lysis of bacterial cultures is a well documented fact. In addition to lytic activity by nonbiologic detergents, one finds that many biologically produced substances have the ability to destroy the structural integrity of living microorganisms. Lysozyme lyses susceptible bacteria by hydrolyzing certain mucopolysaccharides necessary to the ...
