Introduction: The objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. Methods: This is an applied study. With regard to shiftwork schedules of the facto...

Wastewater Treatment Facilities have been built to remove biological and chemical waste from water as it is used. These facilities maintain a healthy environment for organisms as well as people because it removes potentially harmful material and kills pathogens that would easily spread through cities. Phosphorus is a compound of interest because a high concentration of it at discharge will even...

the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. as the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (nssc) proce...

background: untreated leachate is being discharged into the environment in many countries worldwide. leachate treatment methods have not been unified so far due to the variable composition of leachate. moreover, the lack of appropriate treatment and disposal of leachate causes environmental pollution. this study aimed to compare removal efficiency of chemical oxygen demand (cod) and total suspe...

To determine cholesterolin biologicalfluids,use of the ferric chloride-sulfuric acid reagent introduced by Zlatkis et al. (1) is relatively simple and reliable (2, 3), and the sensitivityof the reagent for cholesterol is four to five times greater than that of the Liebermann-Burchard reagent (2). However, Parekh and Jung (4) reported that hydrogen chloride is evolved during the ferric chloride-...

the solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of lewis acids such as aluminum chloride and ferric chloride on silica gel are described.

An improved microprocedure for the determination of tocopherol in blood serum is reported. Tocopherol is oxidized by ferric chloride and the pink complex of ferrous ions with 4,7-diphenyl10,10-phenanthroline (bathophenanthroline) is determined spectrophotometrically. The test is more sensitive than colorimetric methods using 2,2’,2” -tripyridine,2,2’-bipyridine (bipyridyl) or 2,4,6tripyridyl-s-...

Introduction: The objective of this study was to investigate wastewater quality and the efficiency of removal of wastewater contaminants produced by a tile factory by using ferric chloride, ferrous sulfate, ferric sulfate, aluminum sulfate (alum) and poly-aluminum chloride (PAC) coagulants. Materials and Methods: This is an applied study. A composite sample was taken of the wastewater producti...

Introduction: The removal of organic precursors of disinfection byproducts (DBPs), i.e. natural organic matter (NOM), prior to disinfection is considered as the most effective approach to minimise the formation of DBPs. Trihalomethanes (THMs) as the main group of DBPs are categorized and considered to have the potentiality of increasing the rate of liver, kidney and CNS adverse effects. Methods...
