excess sludge minimization in conventional activated sludge pilot plant by three chemical matters
the excess sludge treatment and sludge disposal are major factors to the over-all economy of wastewater treatment plants (wwtp). the ideal solution to the problem of sludge disposal is to combine sludge minimization with contamination removal at the source. in this study, the effect of ozonation, chlorination and 3,3,4,5–tetrachlorosalicylanilide (tcs) to treat part of the return activated slud...

متن کاملBiodesulfurization of Tabas Coal in Pilot Plant Scale
Sulfur emission from coal combustion presents many environmental problems. The techniques used to reduce the amount of sulfur in coal before combustion, include physical, chemical and biological processes.Biological processes based on degradation of sulfur compounds by microorganisms offer many advantages over the conventional physical and chemical processes. The processes are performed und...
متن کاملSimulation and Optimization of a Naphtha Thermal Cracking Pilot Plant
In thermal cracking plants, it is desired to apply an optimal temperature profile along the reactor to minimize the operation cost. In this article a simulator is developed by the use of a mathematical model, which describes the static operation of a naphtha thermal cracking pilot plant. The model is used to predict the steady state profiles of the gas temperature and product yields. Using ...
متن کاملانتقال تکنولوژی از تحقیق و توسعه به تولید نیمه صنعتی (پایلوت پلنت pilot plant) یک محصول شیمیائی
امروزه تکنولوژی در توسعه اقتصادی و اجتماعی همواره یک وسیله ضروری بوده و خواهد بود. اکنون این نتیجه حاصل شده است که علت اصلی کندی کشورهای توسعه نیافته در جهان در پیشرفت های اجتماعی و اقتصادی و حتی فرهنگی، ناتوانی آنها در شناخت یا گسترش تکنولوژی درست و بهره گیری از آن در فعالیتهای تولیدی است و لذا کاربرد اطلاعات و بهره گیری از تکنولوژی پیشرفته و مدرن مستلزم سطح مشخصی از فرهنگ عمومی و مهارتهای علم...
