b liquid solids separation wherein the suspended solids are substantially removed to produce a translucent liquid capable of light transmission and containing primarily dissolved organic and inorganic constituents with dissolved gases c increasing the ph of the translucent liquid through the use of a photobioreactor to remove co 2 and bicarbonate and thereby increase the ph of the translucent liquid to values that convert a significant portion of the ionized ammonium nh 4 to ammonia gas nh 3 d heating the high ph translucent liquid to improve stripping e stripping the ammonia gas from the translucent heated liquid produced in u201c d u201d above that has an elevated ph and temperature with a stripping gas f cooling the stripping gas produced in u201c e u201d above to produce a concentrate from which ammonia can be reclaimed as a product any number of the steps a through f can be performed in a single or multiple reactors for example the liquid solid separation step may consist of dewatering with any of a variety of conventional solids separators followed by gas stripping with a u201c purge gas u201d or use of a single reactor such as a gas flotation device that separates solids while stripping carbon dioxide thereby increasing the ph and removing the suspended solids in the same reactor gas stripping may also occur in a single reactor composed of a photobioreactor incorporating gas stripping or a heated gas stripping photobioreactor fig2 presents an amplified version of fig1 anaerobic digestion a is followed.
