MEGALITE is ideally suited for the immobilization of microbes and enzymes
for ponds, aquaria, continuous wastewater treatment processes, septic systems, wetland
construction, , and sewage treatment. Q. I was planning to use pea gravel or volcanic rock in my pond's bio-filter. How will MEGALITE improve it's performance? A. Because MEGALITE contains so much more surface area than the pea gravel or the volcanic rock, it will allow you to reduce the physical size of your bio-filter and still have a much higher performance. Because of it's enormous surface area for the bacteria to colonize, your ponds water will remain clear longer and your bio-filter will require cleaning less often. Your investment in MEGALITE will more than be made up in savings from water treatments, medications, and labor. It may even make it possible to locate a smaller bio-filter in a limited space. Q. I use gravel and sand as a filtration medium. How will MEGALITE benefit me? A. A cubic foot of gravel adds about 150 square feet of surface area on which microbes attach, a cubic foot of sand adds about 1,500 square feet, and, because of its internal pore space, a cubic foot of MEGALITE adds almost 700,000 square feet of internal surface area in which microorganisms live and thrive. Q. Why is internal pore space so important, and why is MEGALITE such an effective medium? A. Internal pores must be at least 1 micron in diameter to sustain living organisms. Most of MEGALITE's pores are greater than 1 micron in diameter. Internal pore space is important because it protects treatment microorganisms from flushing from each MEGALITE granule, it provides stable support for continuous microbial growth, it optimizes concentration /viability of treatment bacteria, and it provides matrix stability. Q. How much MEGALITE do I use? A. There is no set application rate for biological filtration. The more that is used, the more efficient your treatment will be. Because MEGALITE is sold in 3 different sizes, it can be mixed to achieve different ratios of flow-through. Mix some 2mm with 4mm to increase the fine filtration characteristics of your filter when using low flow rates or larger than normal filter sizes. This avoids higher dp across the filter bed, thus allowing use of low head pumps. Use 4mm alone or mixed with 6mm in deeper bed filters sized for your pond. For higher flow rates in larger filters with deeper beds, increase the percentage of 6mm for high flow rates, and increase the percentage of 4mm to increase the filtration performance for smaller filters. |

MEGALITE is a porous ceramic with its main component being an extruded
diatomaceous earth (same diameter throughout the length of the granule) which is then
kiln-fired. MEGALITE is available in 3 different sizes to achieve different flow
through according to requirements. The 2mm and 4mm sizes are suitable for "sand" type
filters. The 4 mm & 6 mm diameter size are typically used for small and larger pea
gravel filters, and the 6mm diameter size alone may be more suitable for larger gravel
bed filters. Enlarged Granule:

***Important: MEGALITE's specifications are unique. Pore space distribution is important in determining water release and entry of bacteria. The bulk of the pore space must be greater than 1 microns for each of these functions.
