RASCHIG RING FILTER MEDIA:

DIRECTIONS FOR USE:

PURPOSE AND BENEFITS:
AquaVet's Raschig Rings are an efficient biological and coarse mechanical filtration product for use in closed system aquaculture. They are particularly appropriate for high flow power filters, with either open or enclosed filter cartridges, because Raschig Rings easily handle high water flow rates and resist clogging. The rings break up the water flow through the filter, preventing "channeling" or bypassing of the water around the filter materials.

Raschig Rings provide an excellent mechanical filtration, promote extensive biological filtration, and enhance the effectiveness of subsequent filter materials.

BIOLOGICAL FILTRATION:
Raschig Rings have proven extremely effective in promoting biological filtration, because they are an exceptionally good base for nitrifying bacteria. Constructed of a porous ceramic stoneware; Raschig Rings possesses a positive electronic change, so slight it is generally unnoticed, which attracts the nitrifying bacteria needed for biological filtration.

The open ring or "noodle" shape, combined with the porous nature of the stoneware, provide a tremendous surface area which can support a population of billions of bacteria in a relatively small filter compartment area.

MECHANICAL FILTRATION:
Raschig Rings are a very effective mechanical filtering material, especially in coarse screening. Mechanically the filter rings break up the water flow through the filter forcing the water flow to spread evenly without channeling or bypassing or clogging the filter materials. The rings regain and entrap large particles of debris which are worn down by water turbulence and bacterial action.

SPECIFICATIONS:
Raschig Rings are constructed of high-temperature-furnace-fired ceramic stoneware rings with hollow centers, approximately 9/16" (15 mm) in diameter and 5/8" (16 mm) in over all length. Each filter ring has a little over 1 square inch of outer surface area; 1 lb. of Raschig Rings contains about 300 filter rings, with 300 sq. inches of available outer surface area. These figures do not consider the microscopic small surface cavities and porosity of the ceramic material. There are about 10,000 Raschig Rings per cubic foot, with about 10,000 sq. inches of available outer surface area. The approximate weight per cubic foot of Raschig Rings is 55 lbs. Packed Raschig Rings have about 65% free space.

STABILITY:
Raschig Rings are durable, long lasting, and stable indefinitely. They require no special handling procedures. Raschig Rings require only a periodic rinsing to remain effective. Washing and treating with soap, household cleansers, and cleaning chemicals do not interfere with its electronic charge.

COMPATIBILITIES:
Raschig Rings do not affect, and are not affected by water quality, medications, or water conditioners. Raschig Rings are nontoxic and harmless to plants, fishes and invertebrates.
