MAINSTREAM ENGINEERING CORP — Department of Defense SBIR Phase I: Field Sanitation Centers typically convert 240 gallons of potable water per day into greyw

Description

Field Sanitation Centers typically convert 240 gallons of potable water per day into greywater. This greywater must then be transported off-site or properly disposed of on-site. To alleviate this problem, a continuous process to treat the greywater produced is needed. The treated water must meet secondary treatment standards, and the processing system must be rugged, easy to use, consume less than 1 kW of power, occupy approximately 1 yd3, and use minimal consumables. Mainstream Engineering proposes a solution that integrates multiple well-defined technologies, suitable for small-scale applications, into a system that meets the objectives set by the Army. In Phase I, Mainstream will design and fabricate a greywater recycling system capable of producing water suitable for reuse in field kitchen sinks. The continuous system will be optimized and a full-scale prototype will be designed. In the Phase I Option, Mainstream will fabricate an initial full-scale prototype with preliminary electronics and automation, and also perform life testing on the bench-scale unit. During Phase II, Mainstream will perform rigorous field testing, and expects to deliver a field-ready unit at the conclusion of Phase II.
