The Marine Corps currently uses 5 wt% sodium hypochlorite solutions (bottled bleach) as a general disinfectant/sanitizer in their combat field kitchens. Diluted bleach solutions are used for processing fresh fruits and vegetables, water purification, surface sanitizing, and general cleaning use. However, the limited shelf-life of bottled bleach (3-6 months) and the hazardous nature of concentrated hypochlorite solutions place significant logistical burdens on military operations in terms of its transportation and storage. Functioning as a direct replacement for bottled bleach, we proposed in Phase I the development of a batch electro-chlorination system that produces a mixed oxidant bleach replacement (i.e. a 5.0 wt% sodium hypochlorite solution). Our electrolysis approach is highly advantageous since high purity table salt, water and electricity are the only consumables. The breadboard devices developed in Phase I were designed primarily to show the technical feasibility of our electrolysis process, and only limited emphasis was placed on addressing the actual usability of the envisaged electro-chlorinator. Consequently, Phase II will be predominately targeted towards the overall design of the on-site electro-chlorinator from a functionality and usability perspective. Our Phase II effort will conclude with the fabrication and delivery of four prototype electro-chlorinators for field evaluation by the Marine Corps.
