Abstract
A single full-scale primary facultative pond in Sape, north-east Brazi l was monitored for performance and efficiency. The pond had a hydraul ic retention time of 61 days and achieved a 95% BOD5 removal efficienc y and had no helminth eggs in the effluent The effluent failed to meet the WHO faecal coliform guideline for unrestricted irrigation. The po nd was dominated by the cyanobacterium Microcystis and gave better tha n predicted orthophosphate removal. Derails of how the system could be simply upgraded utilizing the same land are discussed.
