SBIR-STTR Award

In order to comply with environmental regulations an maintain its operational effectiveness, the U.S. Navy must examine alternative technologies for wastewater treatment, disposal, and reuse. WASTECH International, Inc. has developed a number of innovative and alternative treatment technologies that are directly applicable to the U.S. Navy's sewage and gray water treatment needs. These treatment technologies are potentially capable of eliminating sludge and producing an effluent suitable for overboard discharge. Under Phase I of this project, WASTECH proposes to design a prototype wastewater treatment system that will provide the most economical means of shipboard treatment of sewage and gray water for overboard discharge and/or reuse, as appropriate. WASTECH's treatment technology involves the microwave incineration of toilet solids, resulting in no sludge generation, as well as ceramic filtration of effluent to significantly reduce the suspended solids concentration in discharge effluent. In addition, WASTECH has developed complementary technologies to disinfect the effluent and reduce dissolved organic matter. It is expected that information obtained from Phase I will make it possible to design integrated wastwater treatment and management systems for all appropriate classes of Navy ships under SBIR Phase II and III.

In order to comply with environmetal regulations and maintain its operational effectiveness, the U.S. Navy must examine alternative technologies for wastewater treatment and disposal. WASTECH has developed a number of innovative and alternative technologies that are directly applicable to the U.S. Navy's sawage and gray water treatment needs. These treatment technologies are potentially capable of eliminating sludge and producing an effluent suitable for overboard discharge. Wastech proposes to develop, build, and test prototype pilot-scale wastewater treatment sub-systems for both sewage and gray water. These pilot-scale prototype sub-systems will be designed to manage waste streams generated by a DDG-51. WASTECH's treatment technologies involve the microwave incineration of toilet solids, resulting in no sludge generation, as well as ceramic filtration of effluent to significantly reduce the suspended solids concentration in discharge effluent. In addition, WASTECH has developed complementary technologies to disinfect the effluent and reduce dissolved organic matter.

Benefits:
WASTECH anticipates commercializing the wastewater treatment components developed under this project as part of its overall business plan to develop products for its residential and commercial markets, including the navy and commercial marine market.
