Abstract: The present invention is a process, a method, and system for recovery and concentration of dissolved ammonium bicarbonate from a wastewater containing ammonia (NH3) using gas separation, condensation, filtration, and crystallization, each at controlled operating temperatures. The present invention includes 1) removal of ammonia from waste (sludges, semi-solids, and solids and liquids) without the use of chemicals at a temperature of at least 80 degrees Celsius, 2) mixing of the gaseous ammonia with carbon dioxide and water vapor and concentrating dissolved ammonium carbonate and ammonium bicarbonate using reverse osmosis at a temperature of between about 35 and 50 degrees Celsius, and 3) crystallizing concentrated dissolved ammonium carbonate and ammonium bicarbonate at a temperature of less than about 35 degrees Celsius to form solid ammonium bicarbonate and ammonium carbonate.

Abstract: The present invention is a system and process for livestock waste management that operates more efficiently than existing technologies with less maintenance and with less chemical process components (and thus chemical handling) with recovery of useful end products. The invention comprises solids separation of the waste to remove solids in excess of about 0.50 mm in size prior to anaerobic digestion followed directly by solids separation preferably using an ultra filter and then ammonia recovery.
