The publication analyses the appropriateness of anaerobic baffled reactors (ABRs) for on-site primary sanitation in low-income communities. COD removal in domestic wastewater by a pilot ABR (3000L) was assessed. Results indicate that COD was sufficiently reduced for the reuse of the water in agriculture, but not for directly discharging it into natural surface or groundwater bodies.FOXON, K.M. ; PILLAY, S. ; LALBAHADUR, T. ; RODDA, N. ; HOLDER, F. ; BUCKLEY, C.A.
