Cavitating Jets for Aquaculture Wast Treatment and Recycling

Concentrated aquatic animal production facilities (CAAP) have recently fallen under new EPA effluent limitations. Compliance with these guidelines creates the opportunity to improve effluent and recycled water quality. Cavitation caused by our FYNAJETS and the collapse of micro-bubbles in water is a low energy, high efficiency method of applying thermal and mechanical stress and chemical oxidation to complex waste streams. DYNAJETS have been shown to reduce total suspended solids (TSS), increase dissolved oxygen (DO) levels, lower Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD), depolymerize proteins, and reduce bacterial populations. Phase I will demonstrate the feasibility of decreasing TSS and Biochemical Oxygen Demand (BOD), and increasing DO in effluent from flow-through CAAP. In addition, we will investigate the removal of ammonia, pathogens, parasites, and pharmaceuticals from recirculating systems. Phase II will optimize the configurations, add the high flux rate DYNAPERM filtration system, and conduct prototype testing.
