EVALUATION OF HYDRAULIC EFFICIENCY OF WASTE STABILIZATION PONDS (WSP)

Steady state conditions are assumed in impulse response analysis and w ell explained in literature. for the tracer test to realise the result s, but this is not always the case when dealing with the wastewater tr eatment plants, where now processes are always in unsteady state condi tions. Beside stimulus response, the now rate has to be measured at th e same during experiment. Several figures were prepared to demonstrate the influence of variable now rate, these figures are important in or der to understand the changes of impulse response by variable now rate . The unexpected change in the flow rate should be strictly observed t o avoid misinterpretation the impulse response results. The base infor mation in data treatment for variable now analysis of impulse are pres ented to assist in data treatment and to obtain more practical perform ance of the WSP.
