This study observed the influence of initial turbidity, pH and temperature on turbidity removal from textile wastewater using nanocellulose filter paper Neolamarckia Cadamba. Response Surface Methodology (RSM) model was employed to optimize create a predictive evaluate performance paper. The RSM statistically evaluated in terms coefficient determination, R2. optimum value 99.39% were found at 6...

Background: Car wash wastewater contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. In this study, the application of electrocoagulation (EC) to treat car wash wastewater has been studied, and the operating parameters optimized. The electro-Fenton (EF) for further contaminant removal was also investigated. ...

the aim of this work was to optimize the coagulation-flocculation (cf) process applied tomunicipal wastewaters (ww). optimization of cf was performed to minimize chemical oxygen demand(cod), turbidity, sludge produced, and some metals in sludge. a box-behnken design was used to evaluate the effects and interactions of three factors such as type of biopolymer (guar, mesquite seed gum and opuntia...

During the last decade, there has been a concern about the relation between aluminum residuals in treated water and Alzheimer disease, and more interest has been considered on the development of natural coagulants such as chitosan. Chitosan, a natural linear biopolyaminosaccharide, is obtained by alkaline deacetylation of chitin. The present study was aimed to investigate the effects of alum as...

In the direct current mode (DC), widely used in electroflocculation (EC), the formation of an impermeable oxide layer on the cathode causes the declining of the efficiency of this process. This disadvantage has been reduced by adopting alternating current (AC). In this study, the effects of AC and DC on operational parameters such as the removal of oils and greases (O&G), color and turbidity fr...

Strains xn12 and xn17 were isolated from activated sludge from a local hoggery, and preliminarily identified as Gram-positive Bacillus and Streptomyces, respectively. Their flocculating activities were mainly in the extracellular materials, and their components were mainly non-ketose polysaccharides, not proteins. Their flocculating efficiencies were over 95 % under the optimal conditions for p...

Background & objectives: Pharmaceutical wastewater contains high concentrations of organic matter, high salt and difficult biodegradability, so it must be treated before discharge to the environment. In this study, it is aimed to evaluate the treatment of pharmaceutical wastewater (methadone feedstock and neutralized capecitabine) using chemical and biological methods. Methods: The laboratory ...
