Abstract

The Caltech Solar Toilet technol. is based on electrolysis of toilet wastewater with TiO_2-coated semiconductor anodes and stainless steel cathodes. This is a potentially viable onsite sanitation soln. in parts of the world that lack the needed infrastructure for centralized wastewater treatment. Prototypes of Caltech Solar Toilets were designed to fit in shipping containers in order to provide toilets and onsite wastewater treatment with clean water recycling. Units were designed to handle the waste of 25 users per day (or 130 L of toilet wastewater). The various prototypes were able to provide for the disinfection of pathogens, redn. of COD (COD), [NH_3], and color at an av. energy consumption of 35 Wh L^(-1). The treated wastewater was recycled for use as toilet flushing water.
