Inactivation of indicator organisms in wastewater treated by a high rate algal pond system.

CONCLUSIONS: The results show that HRAPs are able to remove viral and bacterial indicators to levels acceptable for sub-surface irrigation of non-food crops. Additionally, it was concluded that alternate environmental sources and the potential for re-growth made ASFB unsuitable indicators for pathogenic protozoa in natural pond systems. SIGNIFICANCE AND IMPACT OF STUDY: This study shows HRAPs would be suitable replacements for WSPs in CWMS schemes in regards to pathogen disinfection. Such demonstration of the treatment efficacy of HRAPs, together with their smaller land area requirements relative to WSPs, should facilitate their wider adoption in rural and remote communities.
