Phenol removal in upgraded facultative waste stabilisation ponds.
Treatment of wastewater containing phenol using laboratory scale waste stabilisation ponds enriched with activated sludge was studied. After enrichment, the efficiency of these ponds under high phenol loading rates (i.e. up to 408 kg phenol ha(-1) day(-1)) was studied. At phenol loading rates of 6, 52, 312, 636 and 972 COD ha(-1) day(-1), the phenol removal efficiencies were 77, 69, 76, 59 and 52%, respectively. The results suggest that enrichment is an effective potential method to increase the removal capability of facultative ponds, not only or easily biodegradable compounds but also for xenobiotics.
