Abstract

Wastewater treatment using laboratory scale waste stabilisation ponds enriched with activated sludge was studied. After enrichment, the efficiency of these ponds under high organic loading rates (i.e., up to 2800kg CODha−1day−1) reached a maximum COD removal rate of 970kg CODha−1day−1, which is from 2 to 10 times more than commonly reported values, and suggests that enrichment is an effective method to improve stabilisation ponds.
