[ 1 ] - Kinetics and Adsorption Isotherms Study of Cyanide Removal from Gold Processing Wastewater Using Natural and Impregnated Zeolites
The extraction of gold involves using cyanide which has the potential to impact the environment. Many studies have been done to reduce the environmental effects of cyanide. In this research, the cyanide adsorption on zeolite from gold processing plant tailing dam wastewater was investigated. Results indicated that the pH of the solution, contact time duration, temperature, zeolite amo...
[ 2 ] - Thermodynamic Modeling and Experimental Studies of Bayerite Precipitation from Aluminate Solution: Temperature and pH Effect
Bayerite is one of the phases of aluminum hydroxide which is precipitated by the carbonation of aluminate solutions obtained from sintered nepheline syenite leaching. In this study, the conditions for the bayerite formation were predicted by thermodynamic modeling of the carbonation process and the Bromley- Zemaitis model was used for this purpose. Carbonation experiments were carried out a...
[ 3 ] - بررسی کاهش عوامل بوزا از تصفیه خانه های فاضلاب شهری به روش بیوفیلتراسیون
بیوفیلتراسیون یک فنآوری جدید جهت کنترل آلایندههای هوا با قیمت پایین، بازدهی بالا، عملکرد ساده و عدم ایجاد مواد زائد است. هدف از این پژوهش، بررسی قابلیت حذف و یا کاهش عوامل بوزا با سیستم بیوفیلتراسیون جهت افزایش ایمنی و سلامت پرسنل تصفیهخانه بود. در این پژوهش، از راکتور بیولوژیکی ستون بیوفیلتر با قطر داخلی 14 و طول cm 95 به مدتmonth 12 در مجاورت حوضچه تغلیظ لجن در دمای محیط جهت کاهش بو استف...
