Abstract

The performances of a semi-industrial-scale membrane bioreactor to treat dilute swine wastewater were investigated on a 3 month running period. The treated water was directly reused in the piggery for flushing purposes. The pilot was proved to have good performances in terms of ammonium removal (99%), and COD removal (86%), despite an accumulation of heavy metals in the biological tanks (up to 17 mg/L for zinc and up to 115 mg/L for copper). 79% of the total phosphorus was eliminated through the process, 61% via centrifugation and 18% by biological uptake. The pilot showed a good adaptability to the variations of the loading rates of dilute swine wastewater's major components (COD, TN, TP, heavy metals).
