Aqua Aerobic Systems > Tertiary Filtration

Aqua-Aerobic Systems, Inc. is a private company servicing its customers around the world with performance-proven, quality products and systems that are adaptable to the changing demands of the water and wastewater treatment industry. Our markets range from small to medium sized municipalities to large metro areas around the world, including both domestic and industrial waste streams.


Aqua-Aerobic Systems was first in the market, in 1991, to offer a cloth media disk configuration as analternative to conventional granular media filtration technologies. A history of exceptional operating experience and durability continues to make the AquaDisk® the tertiary filter of choice.




Aqua MiniDisk®

Aqua-Aerobic Systems is well-known throughout the wastewater treatment industry for its complete line of pile cloth media filtration systems including the original AquaDisk® and AquaDiamond® filters. The tradition continues with the Aqua MiniDisk® filter featuring OptiFiber® pile cloth media. This filter is designed to provide economical treatment of smaller flows with the added advantage of retrofitting existing traveling bridge sand filters.

The modular design of the Aqua MiniDisk filter retrofits neatly into existing 9 ft. (2.7 m) wide concrete traveling bridge filter basin, providing more than two times the hydraulic capacity of the original sand filter.

Aqua MegaDisk™

The Aqua MegaDisk™ tertiary filter “expands” on the reliability and exceptional performance of the original AquaDisk® filter, but on a larger scale. The Aqua MegaDisk offers larger diameter disks and fewer mechanical components than the AquaDisk filter. The result is the smallest footprint available, operating in 80% less space than sand filters with comparable hydraulic capacity.


The AquaDiamond® cloth media filter is a unique combination of two proven technologies; traveling bridge and cloth media filters. The result is two to three times the flow capacity of a traveling bridge filter within an equivalent footprint, making it ideal for sand filter retrofits.
