[ 1 ] - Biodegradation of methylene blue from aqueous solution by bacteria isolated from contaminated soil
The use of biodegradation methods by microorganisms in the removal of industrial dyes are widely considered owing to their high efficiency and compatibility to the environment. Therefore, this study aims to evaluate the biodegradation of methylene blue (MB) from aqueous solution by bacteria isolated from contaminated soil. This study was performed in laboratory scale on bacteria isolated and pu...
[ 2 ] - A Review on the Importance of Hormones Monitoring and Their Removal in Conventional Wastewater Treatment Systems
Introduction: Micro pollutants have become one of the most important environmental concerns around the world. These natural and synthetic compounds have been called Endocrine Disrupting Chemicals (EDCs) due to their interfere with the normal function of the endocrine system in humans and animals. They include natural and synthetic hormones and their metabolites, surfactant, insecticide, as well...
[ 3 ] - بهینه‌سازی میزان تزریق کلر در شبکه‌های توزیع آب با استفاده از مدل GANetXL
Background and Objective: one of the steps in water treatment to protect microbial quality of water network is disinfection. Chlorine is one of disinfectants. It is necessary to maintain Free Residual Chlorine (FRC) between minimum and maximum throughout the distribution system in accordance to health standards. This study was aimed to optimize Chlorine dosage in water distribution networks usi...
[ 4 ] - انتخاب بهترین مدل درون یابی قطعی و زمین آماری جهت بررسی تغییرات مکانی فلوراید در آبخوان یزد با استفاده از سیستم اطلاعات جغرافیایی
چکیده زمینه و هدف: سازمان جهانی بهداشت برای استفاده از اثرات مفید( پیشگیری از پوسیدگی دندان) و جلوگیری از انواع اثرات منفی مانند فلورزیس دندانی و اسکلتی، پیامدهای بارداری و فشار خون؛ میزان فلوراید آب آشامیدنی را به عنوان رهنمود 2/1-8/0 میلی گرم بر لیتر بیان می کند. هدف از این مطالعه تعیین بهترین مدل درون یابی قطعی و زمین آماری جهت بررسی تغییرات مکانی فلور...
