Background and purpose: Molasses is colored, toxic and non-biodegradable compound which is found in the wastewater of fermentation industries. This study investigated the kinetic and efficiency of molass dye removal and mineralization in the yeast wastewater using nanocomposite catalysts in ozonation process. Materials and methods: The catalytic ozonation process (COP) of colored...
[ 5 ] - جذب 2و4 دی نیتروفنل از محلول های آبی با استفاده از نانوحفره کربنی CMK-3
Background and purpose: 2, 4 dinitrophenol is the most important nitrophenol compound that is widely used in paints, adhesives, wood preservatives, solvents, pesticides, and explosive materials. Because of the high toxicity and non-biodegradability of 2, 4 DNP, must be prevented from entering the water body. The aim of this study was to evaluate the performance of ordered mesoporous carbon CMK-...
[ 6 ] - بررسی تصفیه سریع غلظت های بالای 2 و 4- دی نیترو فنل از فاضلاب توسط روش نوین ازناسیون کاتالیزوری با نانوکامپوزیتی کربنی
Background and purpose: 2, 4-dinitrophenol (DNP) are carcinogenic and non-biodegradable pollutants that exist at high concentration in wastewater of chemical industries. In this study, treatment and removal of organic materials (COD) in wastewater was carried out by catalytic ozonation process (COP) using carbon Nano-composite catalysts. Materials and methods: This study was conducted in cyl...
[ 7 ] - بررسی حذف کاتکول از محلول‌های آبی به‌وسیله فرآیند اکسیداسیون با ازن و شناسایی محصولات میانی آن
Background and Objectives: Water and wastewater resources contamination, caused by the wastewater discharged from industries, is considered a major threat to human and environment health. Catechol is one of the usual phenolic compounds in wastewater of various industries such as oil and petrochemicals, plastics, resins, and etc, which is highly toxic and resistant to degradation. Therefore, the...
[ 8 ] - بررسی کیفیت هیدروژئوشیمیایی و بهداشتی آب زیرزمینی شهرستان رامیان، استان گلستان
Background and Purpose: Investigation of water quality is an important step for the suitable use of water resources in order to drinking and irrigation. Water quality affects agriculture programming. Hence the need of the study of water quality is strongly considered in the water resources management. Material and Methods: In this study Hydro-geochemical quality of ground water resou...
[ 9 ] - بررسی تغییرات سمیت کاتکول طی فرایند اکسیداسیون با ازن به روش آزمون زیستی
Background and Objective: Discharge of industrial wastewater containing Catechol has adverse effects on human and environmental health. Purpose of this study was to determine the effects of catechol toxicity before and after advanced oxidation process (ozonation process) by bioassay test with Daphnia Magna. Materials and Methods: This study is an applied research in which the toxicity of cate...
[ 10 ] - تعیین کارایی فرایند ازناسیون کاتالیزوری / راکتور بیولوژیکی SBR در کاهش سمیت، معدنی‌سازی و تصفیه‌پذیری پساب حاوی فنل
Background and Objectives: Phenol is one of the industrial pollutants in wastewaters, which due to its toxicity for biological systems various pretreatment processes have been used for its detoxification. In this study, the combination of catalytic ozonation process (COP) and sequencing batch reactor (SBR) were used for detoxification of these types of wastewaters. Materials and Methodology:...
[ 12 ] - Aniline Degradation Using Advanced Oxidation Process by UV/Peroxy Disulfate from Aqueous Solution
This study is focused on removing toxic aniline from aqueous solutions using advanced oxidation process by UV/ peroxy disulfate. In this study, the effect of various parameters including pH (3-9), the level of radiation (ultraviolet 30 watt lamp, number 2-5), peroxy disulfate dose (0.02 – 0.08 mol/l) and the initial concentration (20 – 100 mg/l) at different contact times (10 – 60 min) on the e...
[ 13 ] - Investigation of the Benzene Concentration and Distribution in Tehran Using Geographic Information System Modelling
Introduction and purpose: Air pollution has been recognized as the most important environmental risk factor worldwide. Benzene which is one of the four pollutants attributed to BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) has been proven to be a carcinogenic component. These pollutants can be easily absorbed and taken into the body via inhalation. With this background in mind, the present ...
