Validation testing of disinfection and environmental parameters in ISO 30500: New international standard for chemistry-driven onsite sanitation systems

Abstract

ISO 30500 "Non-sewered sanitation systems -- Prefabricated integrated treatment units -- General safety and performance requirements for design and testing" was published in Oct. 2018. It aims to enable the testing and verification of design, functionality, and performance requirements of an onsite sanitation system that "collects, conveys, and fully treats [human excreta] to allow for safe reuse or disposal of the generated solid, liq., and gaseous output" without being connected to a "sewer or drainage system". In this paper we present the field measurement of E. Coli, MS2 Coliphage, and Clostridium Perfringens spores removal by large-scale (100 L) batch electrolysis from an onsite sanitation system tested in Durban, South Africa.
