de-nitrate is an economical, natural, porous material with a pore distribution and geometry that promotes both aerobic nitrification within the first few millimeters of depth and anaerobic denitrification at the core. The material has a high surface area and supports a high density of bacteria. Although de-nitrate has capacity to trap nitrate, this, as with other nitrate retaining materials, such as certain zeolites and synthetic resins, is quite limited and the primary mechanism of nitrate removal is anaerobic.
KEY FEATURES:
- Removes nitrates, nitrites, ammonia, and organics
- High porosity biological media
- Pore size well suited for anaerobic bacteria
- No danger of hydrogen sulfide production as with sulfur based media
For best results, de-nitrate should be placed to assure the flow of water through it, such as in a canister filter, chemical filtration module, or box filter. Flow rate should not exceed 200L (50 US gallons) per hour.
