Abstract
The present invention relates in general to a method for bacterially treating small-tank toilet systems and an apparatus for using same, and in particular, bacterially treating small-tank portable toilets, such as toilet systems in airplanes, busses, campers, trains, boats, and free-standing portable toilets.
Claims25
A method for treating a tank toilet system comprising the steps of:
- (a) selecting a bacteria and a surfactant;
- (b) charging the tank toilet system with flushing liquid, wherein the tank toilet system is a recirculation tank toilet system and wherein the tank toilet system is selected from the group consisting of airplane toilet systems, bus toilet systems, and train toilet systems;
- (c) combining the bacteria, the surfactant, and the flushing liquid, wherein the bacteria is selected from the group consisting of Bacillus licheniformis, Pseudomonas florescens, Alcaligenes latus, Bacillus subtilis, and Pseudomonas putida and wherein the weight ratio of the bacteria and the surfactant (weight of the bacteria:weight of the surfactant) charged to the tank toilet system is from about 10% to about 50%.
A method for treating a tank toilet system comprising the steps of:
