Abstract: The present method for deodorizing ammonia odor in an ammonia-containing environment includes adding to the environment a non-toxic, aqueous, acidified amine-based ammonia deodorizing composition in an amount effective to deodorize the ammonia odor in the environment. In addition, a method for preparing the ammonia deodorizing compositions and the compositions produced thereby is disclosed.

Abstract: The present invention is a solution for detoxifying contaminants, such as ammonia, chlorine and chloramine, in aquatic systems. The solution includes a composition of an amine-based ammonia detoxifying compound, in an amount effective to detoxify substantially all of the ammonia, and a dechlorinator. An aqueous solution of the amine-based compound is acidified to adjust the pH to form a stable, non-toxic solution suitable for aquatic life. In addition, methods for preparing the detoxifying solution are disclosed.

Abstract: A method for detoxifying ammonia in an ammonia-containing aquatic system comprises adding to the system a novel composition comprising an amine-based ammonia detoxifying solution in an amount effective to detoxifying substantially all of the ammonia, where the solution is non-toxic and has a pH suitable for aquatic life. Further, a method for detoxifying contaminants selected from the group consisting of ammonia, chlorine and chloramine from a contaminated aquatic system comprises adding to the system a novel composition contaminant according to the present detoxifying solution in an amount effective to detoxifying the contaminants, the solution comprising an amine-based ammonia detoxifying compound and a dechlorinator, where the solution is stable, non-toxic and has a pH suitable for aquatic life. In addition, methods for preparing the ammonia detoxifying and contaminant detoxifying compositions and the compositions produced thereby are disclosed.

Abstract: Filter pads useful for filtering and removing contaminants from fluids comprise at least two pad layers of a permeable, nonwoven polymer material, where one pad layer is connected to another pad layer to form a pocket therebetween having an opening extending into the pocket and at least one of the pad layers has sufficient structural integrity or rigidity to maintain the shape of the filter pad in a filter apparatus during use. In addition, methods for removing contaminants from fluids comprise passing fluid through filter pads having a pocket having an opening extending therein.

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.
