RAS (Recirculating Aquaculture System) is a closed loop system which recirculates water. RAS currently requires the use of many costly equipment components: water pumps, oxygen contactors, drum filters, de-gassing units, biofilters and foam fractionators. All these components are needed to create and maintain a sustainably environment for the grow out process. Aqua Hill Aeration now offers new innovative and patented technology for your RAS in the Hydroburst IT/OT and Hydrostream IT/OT. You now have the ability to replace water pumps, oxygen equipment, de-gassing units, foam fractionators all while enhancing the performance of your biofilter. The Hydroburst and Hydrostream have no moving parts and require no maintenance. Using only a low energy consumption blower to operate, these devices create water flow, oxygenate, de-gas and foam fractionate to make your RAS efficient and sustainable.
