The optimization of full-scale biogas plant operation is of great importance to make biomass a competitive source of renewable energy. The implementation of innovative control and optimization algorithms, such as Nonlinear Model Predictive Control, requires an online estimation of operating states of biogas plants. This state estimation allows for optimal control and operating decisions accordi...

Çalışmada, laboratuvar ölçekli farklı filtre malzemesi doluluk oranlarında yukarı akışlı anaerobik sabit yatak sisteminin yarı sürekli (Ysm) ve işletme (Sm) modlarında melas içeren sentetik atıksu için arıtma performansı incelenmiştir. %100 (AF100), %75 (AF75), %50 (AF50) %25 (AF25) malzeme oranına sahip olan 4 reaktör, 0,5, 1 2,0 kgKOİ/m³.gün organik yükleme (YO), 2 günlük hidrolik alıkonma sü...

We consider one-step and two-step simple models of anaerobic digestion that are able to adequately capture the main dynamical behaviour full model ADM1. do not specific growth functions. only require them satisfy certain qualitative assumptions. These assumptions satisfied for concave functions, but they also a large class functions found in many applications. maximisation biogas production wit...

Models such as the Anaerobic Digestion Model No. 1 (ADM1) assume that pH can be calculated directly from the concentration of hydrogen ions. However because pH is, by definition, the negative logarithm of the hydrogen ion activity, and thus pH measurements represent hydrogen ion activities, this approach may lead to a bias between measured and predicted pH values. Implementing ionic strength ef...

Some of the key factors affecting the adaptation of anaerobic digestion processes to increasing levels of salinity were determined in batch tests using brown seaweed as a feedstock. It was found that cultures seeded with non-saline anaerobic inoculum required an adaptation period of up to two months to reach the same level of methane production rate as in those cultures seeded with saline-adapt...
