     although process development is often done in well agitated vessels (e.g. with a retreat curve, pitched blade turbine etc.), there are a sizeable number of contract manufacturers’ still deploying a significant number of anchor agitated process units. for the purpose of observing the zwietering constant value ‘s’ and few industrially important solid–liquid systems, we conducted extensive suspension experiments with anchor agitated vessels for varying d/t ratios (0.74 and 0.73). in this study, zwietering's njs (just suspension speed) and the corresponding ‘s’ factor were obtained for each system over a range of solid loadings. we found that the zwietering constant was strongly dependent on the nature of the solid–liquid system; i.e. different systems had different ‘s’ values for the same geometrical configuration.
