Abstract: Superabsorbent polymers (SAPs) are used for the containment and treatment of wastewaters. SAPs are mixed with a wastewater in amounts sufficient to absorb substantially all of the wastewater and prevent it from leaving a defined containment area. The water can then be evaporated from the SAP to produce a substantially dry polymer composition containing the SAP and the wastewater contaminants. The dry polymer composition is discarded or, when appropriate, used as a fertilizer for plants. Surprisingly, the SAP reduces the odor associated with ammonia containing wastewaters by binding to the ammonia and reducing the ammonia gas present in the airspace around the wastewater. The evaporation process may be conducted in the presence of a heat exchanger to produce cool, fresh air that is used to cool facilities, particularly animal rearing and production facilities.

Abstract: The water, sediment and erosion control apparatus of the present invention includes a water-permeable foam barrier extending generally longitudinal. The barrier has an upstream surface and a downstream surface. The apparatus also includes an apron extending laterally away from at least one surface of the barrier. The apparatus is reconfigurable for different applications by rotating the barrier relative to the apron. The method of the present invention comprises providing a reusable apparatus having an angled barrier and a protective apron, and anchoring the apparatus generally perpendicular to a natural flow of water, such that the water carrying the sediment is slowed and sediment is deposited upstream of the apparatus.
