Nutrient extraction and recovery device for isolation and separation of target products from animal produced waste streams

A system for processing a source of waste to produce at least one target product selected from the group consisting of struvite, potassium struvite, hydroxyapatite, and any combination thereof, the system comprising:

• a chamber-type device comprising at least one wall, a cation exchange membrane having a first side and a second side, and an anion exchange membrane having a first side and a second side, wherein the at least one wall, the first surface of the cation exchange membrane and the first surface of the anion exchange membrane define an interior of a recovery compartment for containing a recovery or draw solution, wherein the chamber-type device is communicatively connected to a gravimetric separator that permits collection of the at least one target product from the device, and recirculation of, the recovery or draw solution to the device, wherein, following insertion of the chamber-type device into the source of waste, the second surface of the cation exchange membrane and the second surface of the anion exchange membrane are in contact with the source of waste, wherein the recovery or draw solution comprises at least one cation and at least one anion, wherein the at least one cation is selected from the group consisting of Na+, K+, Mg2+, Ca2+, NH4+ and combinations thereof, and the at least one anion is selected from the group consisting of HPO42−, PO43−, Cl−, HO−, HCO3−, and HCOO− and combinations thereof, and
• wherein the at least one cation and at least one anion in the recovery or draw solution precipitate to form the at least one target product, and wherein the system does not require an electric current supply to produce the at least one target product.
