Cutting-edge filtration products with patented designs and exceptionally high biological surface area.
The Delta Advanced Fluidized Bed Filter is the most advanced fluidized bed filter on the market today. Features a tapered column design (3 US patents granted, 2 pending) that ensures years of trouble-free service. The new column design greatly reduces the chance of an accidental media "wash out." As the chamber widens at the top, the greater cross-section of the cylinder slows the water's velocity and contains the media. The filter can also be plumbed (by the customer) with a media bypass line that allows the operator to feed water into the filter media, internally and externally, to reduce the chance of accidentally clogging the center supply tube.
Fluidized Bed Biofilters—featuring US and foreign patents—are simple, extremely compact, self-cleaning, quiet and easy to use. Water is pumped up through a bed of sand, "fluidizing" the sand media and providing excellent water/media contact. Fluidized bed biofilters virtually eliminate the need for internal void space, allowing them to pack a lot of surface area into a small space.
