This filter provides stackable residues with less water content than the
drum filter, it added.
After first passing through a
drum filter to remove large debris (twigs, leaves and vegetation), aeration adds oxygen to the water, which then flows through the entire facility via gravity, making for a very cost-efficient hatchery.
Instead, all filtration is provided by a Polygon
drum filter, whose 70-micron screens are finer than the 150-micron screens used in standard systems.
The "Smart Sponge 55" has been designed as a self--contained, disposable 55-gallon
drum filter system.
This Smart Sponge 55 has been designed as a self-contained, disposable 55 gallon

The product has been designed as a self-contained, disposable 55-gallon
drum filter system.
Each four-tank system includes a microscreen rotating
drum filter and protein skimmer for removal of solid and suspended wastes, a moving or static bed biofilter for ammonia and nitrite removal, supplemental oxygenation that is monitored and controlled using oxygen sensors and PLCs, micro-bubble aeration diffusers, centrifugal pumps and propeller pumps for water movement, UV sterilizers for return water disinfection, and degassing columns for [CO.sub.2] removal.
The filtration system consists of a buffer tank in which a rotating
drum filter is placed.
The small disposable rotary
drum filter has a drum size of 3" diameter by 4.5" long, giving an effective filtration area of approximately 42 [in.sup.2].
Any remaining fines entrained on the
drum filter media are removed when it indexes in front of the internal backflush spray bar.
