Aquaculture Systems Technology

The motorized embedded propeller is used for frequent washing of the media, removing captured solids and excess media biofloc. The sludge then settles to the bottom of the unit where it is drained, reducing water loss that is normally associated with backwash processes. With Propeller Bead filters, you will only lose 10% of the water you that you would normally lose with run-of-the-mill sand filters.

AST has both standard flow and high flow (pressurized) Propeller Bead filters. High flow filters can process flow rates of up to 1200 gpm, making them perfect for large systems that need frequent turnover.

Suitable for high loads that are typical of aquaculture applications, these filters are capable of handling ammonia loads 50% – 100% higher than standard bead filters. You will be able to lower your overall water and head loss – our innovative backwashing process is gentle enough to protect the biofilm and keep the environment healthy.
