Bod removal rates of waste stabilization ponds as a function of loading, retention time, temperature and hydraulic flow pattern

This study evaluates the influence of loading, detention time and temperature on the first order BOD removal coefficient K₁. Numerical values of K₁ are derived from semi-continuous-flow laboratory units of sewage ponds and introduced into the design formula for a multi-stage continuous flow reactor. There was a good correspondence (r = 0.92) between the computed BOD removal rates and the empirical results obtained from three large-scale multi-stage pond systems.
