Filters for Clean Water
Purpose: What is the effect of combining different natural materials with activated filter media on the effectiveness of filtering out ammonia, nitrite, and nitrate? Procedure: In this experiment, different combinations of active (activated carbon and zeolite crystals) and inactive (sand, gravel, and cotton balls) were tested on the effectiveness of ammonia, nitrite, and nitrate filtration. Conclusion: The effect of combining different filter medias was that the slower the water ran through the filter with an active ingrediant, the more effective it was in removing ammonia, nitrite, and nitrate.
