Membrane filtration is one of the alternatives suggested for the future drinking water production. Worldwide, the total number of ceramic membrane usage for water treatment is increasing swiftly and this is the first ceramic filtration study which is applied to a surface water treatment in a tropical region. This study was conducted to investigate the removals of natural organic matter and path...
در این مطالعه بهینه سازی چهار پارامتر (ph اولیه پساب، cod اولیه پساب، غلظت منعقدکننده ها و غلظت لخته سازهای کاتیونی) به منظور کاهش آلاینده های پساب کارخانه بازیافت کاغذ مطابق روش پاسخ سطح (rsm) بررسی شدند. برای تعیین بالاترین میزان حذف کدورت و cod پساب به وسیله منعقدکننده های آلوم و پلی آلومینیوم کلراید (pacl)، 30 آزمایش و به وسیله منعقدکننده ها و لخته سازهای کاتیونی پلی آکریل آمید (c-pam)، 120...
The aim of this work was the study of the combination of an inorganic pre-polymerized coagulant (PACl) with ferric species and polysilicic acid in various mixing order, Al/Fe/Si and OH/Al molar ratios, and two polymerization techniques for the production of a unique reagent representing a coagulant, more efficient than commercial PACl-18 and laboratory prepared PACllab for water or wastewater t...
background: today with population growing, surface water is one of the most important water resources used for domestic and industrial consumptions. in order to purify the surface water, coagulants materials are used. the purpose of this study was to assess the possibility of using poly aluminum chloride (pacl) in water refinery number 1 in city of orumieh and investigating its health effects. ...
Coagulant aids are useful chemicals that enhance the efficiency of coagulation sedimentation treatment. For this purpose, it is necessary to choose safe avoid various risks health those who use treated water. The chitosan, an abundant natural polysaccharide, as a coagulant aid significant not only for water treatment but also effective utilization unused resources, which mostly wasted. We exper...
enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...
Background & Aims: Humic acid is a major agent in trihalomethanes (THMs) formation during chlorination process, which are known as carcinogens. The aim of this study were to investigate the removal of humic acid by three coagulants including PACl, alum and ferric chloride from water sources and their effect on zeta potencial. Materials & Methods: This study was conducted  ...
BACKGROUND The study compares the eradication success of standard first-line triple therapies of different durations (7, 10, and 14 days). MATERIALS AND METHODS A total of 592 naive Helicobacter pylori-positive patients were randomized to receive pantoprazole, amoxicillin, and clarithromycin or metronidazole for 14 days (PACl14 or PAM14), 10 days (PACl10 or PAM10), or 7 days (PACl7 or PAM7). ...
