WebbConcept: Organic loading rate (OLR) is defined as the how much organic matter is entering in to trickling in one day per unit volume. It is expressed in kg/m 3 /day. It is given as: \(u = \frac{W}{{VF}}\) Where W is BOD in Kg/day; V is the volume of a trickling filter in m 3 and F is the recirculation factor.. This recirculation factor, F is given as Webbthe recirculation factor in simulations of a flameless furnace, different simulations of non-reactive coflow jets were carried out in 2D and 3D as support of this work. These simulations were generated using experimental data from literature [12 …
