Abstract
Wastewater stabilisation ponds are a good alternative for treating different types of wastewaters due to their simplicity, effectiveness and low cost. It has been found that the volumetric organic loading (VOL) on ponds affects pathogen removal inversely whereas temperature has a positive effect. This was confirmed in the present studies on "anoxic" ponds, which were loaded in the range between conventional organic loading levels for anaerobic and facultative stabilisation ponds. In addition, other environmental factors (light, pH, dissolved oxygen (DO) concentration, and oxidation-reduction potential (ORP) were also found to influence pathogen removal in the model ponds. The effects on faecal coliform removal of volumetric organic loading and temperature are represented in the form of a multiple regression model. The equation developed was found to apply at a significance level of 95% with p < 0.001.
