Abstract

An ammonia capture recovery system is disclosed. The ammonia capture recovery system may include pretreatment with conventional solid removal devices and a single or a series of hydrophobic membrane concentrators receiving a heated ammonium containing influent either heated to a sufficient temperature to convert ammonia to ammonium or containing sufficient alkali to convert ammonia to ammonium in the influent. The heated ammonium containing liquid is pumped through the hydrophobic membrane concentrator and the hydrophobic membrane concentrator receives an acid. The acid then reacts with the extracted gaseous ammonia and ultimately forms a saturated ammonium salt product that is discharged from the hydrophobic membrane concentrator, the hydrophobic membrane concentrator includes a feed line, a plurality of hydrophobic membrane modules, a diluted acid source and a concentrated acid source and tanks to receive the saturated ammonium salt product and the low ammonia effluent.
