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...

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 fact...

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...

In the present study, several pre-polymerized coagulants of iron and aluminum were tested for their efficiency towards As(V) and As(III) removal from water sources. The results showed that the pre-polymerized coagulants of iron, such as poly-ferric sulfate and poly-ferric silicate chloride, were very efficient for As(V) removal. With regard to As(III) removal, among all examined coagulants, inc...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

introduction: controlling parenchymal hemorrhage, especially in liver, is still one of the challenges surgeons face with when they try to save the patients’ lives despite improvements in surgical procedures. there is a research contest between the researchers in this field to introduce more effective methods. this study aimed to compare the hemostatic effect of ferric sulfate and ferric chlorid...

results in all the groups, complete hemostasis occurred. hemostasis times of different concentrations of ferric sulfate were significantly less than those of the control group (p < 0.001). objectives this study attempted to determine the haemostatic effect of ferric sulfate and compare it with the standard method (suturing technique). materials and methods in this animal model study, 60 male wi...
