Development of WISH type transportable toilet with water circulation; WISH hoshiki kahangata junkan suiryushiki toire no kaihatsu

Abstract

Described herein are a proposed ``WISH (wind and solar hybrid) type portable toilet with water circulation,`` in which wind and solar power generation units are combined, and specifications of the toilet unit for 2 persons. It needs 2.2m{sup 3} of initial charge of water, which can be circulated by power stored in the battery unit in 2,600 to 3,000 cycles. Water can be kept at a pH level of 8 or lower, when circulated 200 times or less for a day. This number is increased to 500, when 2 units are installed. Dirty water is treated by an agent and circulated without being exhausted and without releasing offensive odor. Circulating water is recycled while being totally sterilized, whereas sludges are exhausted after being solidified by a powerful coagulant. The toilet unit is equipped with a pump (50W) and fan (75W). The solar unit generates power of at least 1.08Wh/day and the wind unit is equipped with a small-size generator having a rated capacity of 300W. The toilet units are commercialized and showing good results. 2 refs., 5 figs.
