Some investigations on PHA production using activated sludge as inoculum
This paper indicates that activated sludge under certain conditions can achieve levels of polyhydroxyalkanoates (PHA) accumulation which would enable the economic recovery of this precursor of biodegradable plastics. The effects of C/N ratio and temperature on polyhydroxyalkanoates production were evaluated. Acetate uptake, ammonium consumption, oxygen uptake and PHA production were studied und...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
lime stabilization of waste activated sludge
background sewage sludge (biosolids) is a byproduct of wastewater treatment that accumulates in large quantities. effective stabilization and disinfection of sewage sludge prior to land application are necessary to not only protect human health, but also to induce the public its benefits and safety. currently, many wastewater treatment plants in iran dispose great amounts of untreated sewage sl...
متن کاملKraft pulp mill effluent treated by activated sludge and aerated lagoon genotoxicity assess
Organic compounds present in the bleached kraft pulp mill (BKPM) effluents may be reduced by biological treatment like: activated sludge (AS) or aerated lagoon (AL). However, after biological treatment, BKPM effluent still contains specific compounds. Some of them have been related with chronic effects (DNA damage, reproductive and physiological) observed on fishes exposed to BKPM effluents. Th...
متن کاملDisinfection of raw wastewater and activated sludge effluent using Fenton like reagent
BACKGROUND AND OBJECTIVES Water shortage problems have led to find either new water resources or improve wastewater treatment technologies in order to reuse. Due to less performance of previous units in microbial removal, disinfection has become a necessary step in wastewater treatment plants. In the present study performance of hydrogen peroxide (HP) and modified Fenton's reagent (HP + Cu(++))...
