Abstract
Zeolite-impregnated pads useful for filtering and removing ammonia from fluids and for enhancing plant growth and microbial activity comprise a nonwoven polymer pad having zeolite bonded substantially throughout the pad by a non-toxic adhesive composition. In addition, methods for removing ammonia from fluids comprise passing fluid through zeolite-impregnated pads, and methods for growing plants in situ and methods for growing bacteria comprise using zeolite-impregnated pads to enhance growth.
