Abstrakt: Flocked textile surfaces have been investigated as high surface area, bio-filter materials for bioremediation of low concentration ammonia contaminated water. These conditions are encountered in fish-growing tanks used in commercial closed-system (recirculating water) aquaculture (fish farming). Nitrosomasand Nitrobacterbacterial species were used for bio-conversion. Ammonia depletion rates (ADR) for various commercial and experimental bio-media materials were experimentally determined. Overall, ADR values of various bio-media materials were found to 1) be 1.5x and higher for flocked surface bio-media than for non-flocked bio-media, 2) decrease as the flow rate of ammonia-polluted water through the bio-media increases (this effect was not linear), and 3) generally increase as the bulk surface area per volume of the bio-media increases. These observations suggest opportunities for further study of flocked bio-media materials.
