[ 1 ] - Effect of temperature on pH, turbidity, and residual free chlorine in Sanandaj Water Distribution Network, Iran
One of the parameters responsible for decreased water quality in a distribution system is temperature changes. This study was conducted to examine the effect of temperature on pH, turbidity, and residual chlorine in Sanandaj, Iran, Water Distribution System. The required water samples were taken from 85 stations during April to October 2014. Sampling was carried out over 6 months and twice per ...
[ 2 ] - Adsorption of nitrate from aqueous solution using activated carbon-supported Fe0, Fe2 (SO4)3, and FeSO4
In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...
[ 3 ] - Anammox enrichment and constructed wetland inoculation for improvement of wastewater treatment performance
This study contributes to the improvement of low-cost biotechnology for wastewater treatment in constructed wetlands (CWs). Constructed wetlands are energy efficient engineered systems that mimic the treatment processes of natural wetlands, removing polluting organic matter, nutrients, and pathogens from water. The aim of this study was to investigate the advisability of the inoculation of hori...
[ 4 ] - اکسیداسیون کاتالیتیکی مونوکسید کربن با استفاده از نانوذرات اکسید مس تثبیت شده بر روی دیاتومیت
Background and aims: Carbon monoxide (CO) is a highly toxic, colorless, and odorless gas with a density close to the air, which is produced by natural processes and anthropogenic sources and is well known for its potential harmful and poisonous effects on humans. Inhalation of carbon monoxide gas can impair the heart and central nervous system. Diatomite supported nano copper oxide catalyst w...
[ 5 ] - شناسایی و مبارزه با رشد جلبکی در منابع آب با استفاده از نانوذرات اکسید روی
افزایش غلظت مواد مغذی مانند نیترات و فسفات موجب شکوفایی جلبک در منابع آب می‌شود. این شکوفایی جلبکی باعث تغییر در طعم و بوی آب شده و کیفیت آب را کاهش می‌دهد. در این پژوهش رشد جلبکی در منابع آب (سد یامچی اردبیل) با استفاده از نانو ذرات اکسید روی بررسی شد. بعد از کشت جلبک‌های جمع‌آوری شده از سد یامچی و سپری شدن زمان لازم به‌منظور رشد جلبک، شناسایی جلبک‌ها، با تهیه لام و مشاهده در زیر میکروسکوپ ان...
[ 6 ] - Effects of dried Rose Petals (Rosa damascena) on the antioxidant capacity of Green and Black Tea
The health benefits of green and black tea are mainly associated with their antioxidant potential and phenolic compounds. The present study aimed to evaluate the effects of dried rose petals (Rosa damascena) on the antioxidant capacity of green and black tea. Antioxidant capacities of tea and rose infusions were assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2-azinobis-3-<...
[ 7 ] - جذب فلوراید توسط نانوذرات اکسیدآهن تثبیت شده بر روی دیاتومیت: تعیین شرایط بهینه، سینتیک ها و ایزوترم های جذب
Background and Objectives: Fluoride has both beneficial and detrimental effects on health. Therefore, it is important to determine its concentration in drinking water. Dental fluorosis and skeletal fluorosis are health effects caused by long term exposure to high levels of fluoride in drinking water. The aim of this research was to investigate fluoride removal using modified diatomite-supported...
