SeaRAS Aquaduct

SeaRAS Aquaduct

· Water transport
· Degassing (CO2, H2S, NH3)
· Protein Skimming

Energy and cost efficient – in a single unit

The synergy in the multifunctionality of the Aquaduct, enable a complete redesign of the standard RAS systems, as presented in SeaRAS Reactor SeaRAS Aquaduct is a stand alone unit that easily can be retrofitted into existing RAS facilities to improve CO2 degassing and skimming capacity. The principle is that air is inserted into the water stream in the vertical intake pipe and along the horizontal pipe. This air is interacting with the main water stream and drawn out of the system together with foam and fractions of dirty water before the main water stream goes back into the same tank or over to another tank.

Fractions of water and foam are sucked out together with the air and separated in a cyclone, where the air leaves the system and the dirty water goes into the waste water system for further treatment. This water contains a concentration of the smallest particles in the inlet water to the Aquaduct. These particles have bonded themselves to the water bubbles and been skimmed out in the skimming towers during the transport through the Aquaduct.

The SeaRAS Aquaduct is the first combined skimmer/degasser that also is fully instrumented. The quality of the inlet water, the outlet water and the sludge water is monitored in real time together with the gas out of the degasser. This will give a complete mass balance and show the performance of the Aquaduct at any time. It will tell you how much CO2, H2S and other gasses are removed from the water at any time.
