Liquid Circulation Velocity

In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was examined. Also, the possibility of theoretical prediction of this liquid circulation velocity was assessed. The correlation originally proposed by Glennon et al. (Chem. Eng. Commun. 121 (1993) 183-192) for two phase system liquid velocity prediction was extended and corrected for application to three phase systems. The accuracy of this new correlation was tested on our experimental data. The corrected correlation shows higher accuracy than the originally proposed one. In addition, the influence of reactor geometry and solid loading on reactor working performances was established.

Activated Sludge Systems

Steady-state models are presented to describe the wastewater treatment process in two activated sludge systems. One of these makes use of a single complete-mix reactor; the other one involves two complete-mix reactors arranged in series. The in-series system is equivalent to what is known as the “two-phase” activated sludge, a concept which is now being launched throughout Poland in conjunction with the PROMLECZ technology under implementation. Analysis of the mathematical models has revealed the following: (1) treatment efficiency, excess sludge production, energy consumption, and the degree of sludge stabilization are identical in the two systems; (2) there exists a technological equivalence of “two-phase” sludge with “single-phase” sludge; (3) the “two-phase” system has no technological advantage over the “single-phase” system.

The distribution kinetics of 35 2-furylethylene derivatives in two-phase system 1-octanol-water was investigated. The transport rate parameters in direction water-1-octanol (l1) and backwards (l2) are partition coefficient P = l1/l2 dependent according to equations l1 = logP - log(βP + 1) + const., l2 = -log(βP + 1) + const., const. = -5.600, β = 0.261. Importance of this finding for assesment of distribution of compounds under investigation in biosystems and also the suitability of the presented method for determination of partition coefficients are discussed.
