[ 1 ] - Recycling process of spent bleaching clay: Optimization by response surface methodology
Oil refining is an inevitable step in production of edible and industrial oil. Bleaching is the most important process among the refining processes. Bleaching adsorption is the most common method and clay is the most widely used adsorbent in this method. Disposal of bleaching clay, as a waste from re-refining plants, makes many environmental problems and economic losses. In the current study, t...
[ 2 ] - Artificial neural network forecast application for fine particulate matter concentration using meteorological data
Most parts of the urban areas are faced with the problem of floating fine particulate matter. Therefore, it is crucial to estimate the amounts of fine particulate matter concentrations through the urban atmosphere. In this research, an artificial neural network technique was utilized to model the PM2.5 dispersion in Tehran City. Factors which are influencing the predicted value consi...
[ 3 ] - Estimation of exposure to fine particulate air pollution using GIS-based modeling approach in an urban area in Tehran
In many industrialized areas, the highest concentration of particulate matter, as a major concern on public health, is being felt worldwide problem. Since the air pollution assessment and its evaluation with considering spatial dispersion analysis because of various factors are complex, in this paper, GIS-based modeling approach was utilized to zoning PM2.5 dispersion over Tehran, du...
[ 4 ] - بررسی تفکیک و جداسازی پسماند در مناطق 22گانه شهر تهران با استفاده از سیستم اطلاعات مکانی
یکی از مهمترین راهکارهای مدیریت مناسب پسماند شهری که در حال حاضر بهعنوان اولویت اول در مدیریت پسماند شهری در بسیاری از کشورها در کانون توجه قرار گرفته است، تفکیک و جداسازی از مبدأ است. تحقیق پیشرو با استفاده از آمار مربوط به جمعیت ساکن و تولید و تفکیک پسماند، به کمک سیستم اطلاعات مکانی (GIS)، به بررسی میزان پسماند تفکیک شده مناطق 22 گانه شهر تهران طی سالهای 92-89 پرداخته است. پسماند تر با %...
