The present study aimed to assess and compare the ability to remediate synthetic textile and industrial wastewaters by Fenton treatment, a biological system and sequential treatments using Aspergillus niger (A. niger). All studied treatments were found to be effective in decolorization of the effluents under study. Fenton treatment followed by A. niger showed excellent potential for the maximum...
This paper examined the efficiency of multivariate linear regression (MLR) and artificial neural network (ANN) models in prediction of two major water quality parameters in a wastewater treatment plant. Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) as well as indirect indicators of organic matters are representative parameters for sewer water quality. Performance of the ANN m...
The total carbonaceous biochemical oxygen demand test is described, and experimental data demonstrating its stoichiometry, precision, and accuracy are presented. The test is more reproducible and faster than the current 5-day biochemical oxygen demand test procedure, and if a respirometer is used, the effects of toxic chemicals, pH changes, and nutrient imbalances can be routinely monitored. Th...
The health of a river depends on the quality of its water, which is influenced by the presence of pollutants. The quality of water is generally assessed by a range of parameters, which express physical, chemical and biological composition of water (Meybeck and Helmer 1992). This research deals with some specific water quality parameters of the Buriganga River, which include: temperature, pH, di...
In the context of removal biochemical oxygen demand (BOD5) from food and beverages production wastewaters, this paper reports capabilities SBA-15 modified with (3-aminopropyl)-triethoxysilane (S-APTES) N-[3-(trimethoxysilyl)propyl]aniline (S-Aniline) in glucose, fructose sucrose at very high concentrations (350,000 mg/L for 350,000 170,000 sucrose), i.e. sugars most widely used as sweeteners be...
The vermifilter (VF) is regarded as a sustainable solution for treating rural sewage. However, few studies have investigated the performance of full-scale vermifilter. objective this study to evaluate in reducing organic matter, nutrients, and antibiotic-resistant bacteria contained Influent effluents were obtained from sewage treatment plant using VF UV disinfection system. results show signif...
Most of distilleries in India use biomethanation process to treat the spent wash generated during the alcohol process, to ensure the effective treatment all distillery industries follow 13 fold dilutions due to which tremendous amount of spent wash is generated. 8 -15 l of spent wash was generated during 1 l of alcohol, thus distillery industries consume more water and produce waste water on a ...
background wastewater effluent in hospitals has been increasing during the recent decades due to developments in medical services and products. objectives this study aimed to investigate the qualitative parameters of effluent wastewater in hospitals affiliated to babol university of medical sciences (bums). materials and methods four hospitals were included and their wastewater effluent was stu...
Background and Objectives: One of the complete treatment processes for industrial and municipal wastewater treatment is membrane bioreactor process which has dominant potential in process and operation sections. This study was conducted to compare the performance of extended aeration activated sludge (EAAS) with submerged membrane bioreactor (SMBR) systems in the treatment of strength wastewate...
Background and Objectives: Advanced Sequencing batch reactors (SBR) are one of the most suitable modified activated sludge systems. Due to low cost, optimal efficiency, and easy operation, they are recognized as an effective biological treatment system. The purpose of this study was to determine the performance of the SBR biological process in the removal of organic matter and nutrients from Ya...
