La digestión anaerobia de estiércol vacuno para producir biogás es una biotecnología asequible que implica la producción ácido sulfhídrico (H2S), el cual corrosivo y limita vida útil los biodigestores en este bioproceso tiene lugar, por lo su control vital, especialmente grandes volúmenes. Sin embargo, las alternativas cuantificación gas son costosas complejas, limitando implementación a lugare...

Abstract Water scarcity and wastewater management are two most serious environmental problems faced by developing countries like India. Recycling reuse of the treated for non-potable purpose may significantly reduce stress on fresh water requirement. Anaerobic digestion methods used to treat discharge from various fields. Software tools provide an opportunity engineers create models which repre...

Knowledge of the net energy production of anaerobic fermenters is important for reliable modelling of the efficiency of anaerobic digestion processes. By using the Anaerobic Digestion Model No. 1 (ADM1) the simulation of biogas production and composition is possible. This paper shows the application and modification of ADM1 to simulate energy production of the digestion of cattle manure and ren...

The Anaerobic Digestion Model No. 1 (ADM1) was applied for the mathematical simulation of the thermophilic mono-fermentation of maize silage. Data from a period of 140 days of pilot plant operation were used for model calibration. The substrate characterization in terms of carbohydrates, proteins, lipids and inert matter was based on data derived from fodder analysis. The model was capable of a...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

Many microbial ecosystems can be seen as microbial 'food chains' where the different reaction steps can be seen as such: the waste products of the organisms at a given reaction step are consumed by organisms at the next reaction step. In the present paper we study a model of a two-step biological reaction with feedback inhibition, which was recently presented as a reduced and simplified version...

Biomethane is a renewable product that can directly substitute its fossil counterpart, although synthesis from residual biomasses has some hurdles. Because of the complex nature both and microbial consortia involved, innovative approaches such as mathematical modeling be deployed to support possible improvements. The goal this study two-fold, we aimed modify part Anaerobic Digestion Model No. 1...
