Abstract: The objective of this proposal is to demonstrate the feasibility of the proposed Galley-Scullery Water Conservation System (GSWCS) for Navy shipboard applications. The core technology of the GSWCS is an innovative ozone contacting device, which generates ozone in micro-bubbles. Ozone, a strong oxidant, is capable of reacting with many substances by directly or indirectly attacking the bonding substrates yielding dioxide and water. It is a proven technology that can effectively remove all BODs and organics in gray water. Ozone can be generated through the air, creating a sustainable resource within the constraints of a limited shipboard environment. Ozone in micro-bubbles, which is about 1000 times smaller than the bubbles generated conventionally, provides tremendous surface area and low buoyancy. This dramatically increase the contacting surface and residence time for ozone oxidation and thus makes a compact, lightweight, and low maintenance system attainable. The ozone treated water is then further polished by a self-cleaning filter and sterilized by a UV light. The resulting effluent has a quality that can be recycled continuously for reuse. A complete system can be built into a shelf style unit or a compact unit for under counter installation.
Benefits: Ozone can be produced from the air where and when it is needed. This greatly simplifies the logistic operation by eliminating shipping and storage. It is not carcinogenic or explosive and is safe to use. The innovative ozone contacting device minimizes the contacting tank size and eliminates the recirculating loop used in conventional oxidation systems. Instead, a compact system can be created for shipboard and mobile applications. As a result, the system is practical for the Navy and marine applications. This developed technology can also be applied to commercial and industrial wastewater treatment in general. It is particularly suitable for mobile units used for on-site treatment to eliminate the high cost and on-going legal liabilities of shipping waste off-site.
