a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province
اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Aeration of anaerobically digested sewage sludge for COD and nitrogen removal: optimization at large-scale.
The paper will report about the experiences at an Austrian large wastewater treatment plant of 720,000 population equivalents, where anaerobically digested sewage sludge is further stabilised under aerobic conditions. Enhanced stabilisation of the anaerobically digested sludge was required at the plant in order to get a permit for landfill disposal of the dewatered stabilized sludge. By impleme...
متن کاملA Modified Aeration Process for Promoting Nutrient Removal Using Water Hyacinth to Treat Sewage
To upgrade some conventional aeration processes, a lab-scale system for promoting nitrogen and phosphorus removals was set up and studied through a series of experiments, in which water hyacinth was planted on the surface of the mixed liquor in aeration tanks. The main purpose of this study was to evaluate the effects of (1) aeration, (2) organic load (chemical oxygen demand) and (3) residence ...
متن کاملAeration and de-aeration at bottom aeration devices on spillways
Aeration devices are introduced along chute spillways and at bottom outlets to prevent cavitation damage in high velocity flows. Bottom aerators are characterised by large quantities of air entrained along the jet interfaces but also by a strong de-aeration process near the impact of the water jet with the spillway bottom. In this paper, the aeration and de-aeration occurring respectively in th...
متن کاملNitrogen Removal Efficiency of an A2/o Bio-reactor Treating Domestic Sewage Mixed with Landfill Leachate and Fecal Sewage
A set of anaerobic-anoxic-aerobic (A/O) bio-reactor system was used to treat domestic sewage mixed with landfill leachate and fecal sewage in Datansha Sewage Treatment Plant in Guangzhou China. The experiment investigated the optimal mixing proportion of treating landfill leachate, fecal sewage mixed with domestic sewage synchronously and the optimal running conditions for the removal efficienc...
