ABSTRACT:
A method and apparatus for removing ammonia nitrogen from wastewater at any given temperature. The apparatus and method includes the concept of increasing the pH of the wastewater to a highly basic condition, exposinng the wastewater to a vacuum having an absolute pressure at least approaching the vapor pressure of the wastewater proportional to the given temperature whereby ammonia gas is then desorbed from the wastewater, and subsequently absorbing the desorbed ammonia in a body of liquid having a pH substantially less than the highly basic condition of the original wastewater.
