1. A method of removing ammonia from a stream of used dialysate solution in a dialysis system, the method comprising:

  • passing the stream of used dialysate solution having a pH through a first reactor;

    raising the pH of the stream of used dialysate solution in said first reactor to a level sufficient to substantially convert ammonium ions in said stream to gaseous ammonia;

    releasing the gaseous ammonia from said stream by allowing it to diffuse through a semi-permeable hydrophobic membrane at the outlet of said first reactor;

    receiving the gaseous ammonia through a gas channel into a second reactor; and

    capturing and removing the gaseous ammonia in said second reactor.
