Abstract

See full text

An ammonia capture and recovery system comprises five process steps, including an ammonia removal step, an ammonia recovery step, a product granulation step, a granulated product wax-coating step, and a granulated product encapsulation step. These steps are modular in that multiple approaches are valid for each step if it meets the process requirements for the next influent. Also, a method of taking ammonia-containing wastewater and producing several water fractions (preferably of decreasing volume and increasing purity) and a time-release ammonium-containing fertilizer, resulting in a sustainable nitrogenous fertilizer product that reduces fertilizer use and subsequent nutrient runoff while being produced from wastewater and not fossil fuel or hydrogen sources.
