The PRISA process (Phosphorus Recovery by ISA) can be integrated into the sludge treatment of a municipal wastewater treatment plant (wwtp). Related to the phosphorus inflow load to the wwtp, the process enables a recovery up to 40%. The recovered phosphate can be used either in agriculture or can be sold to the phosphate industry.

Although precipitation (most often Calcium Phosphate or Struvite (=MAP)) from the sludge liquor is relatively easy the main disadvantage of this approach is the fact that most of the P is separated from the liquor in an earlier stage of the waste water treatment process. Therefore the overall recovery potential is .

Ideally, the materials recovered using phosphorus removal and recovery technologies should be readily available for reuse with limited further processing. For reuse as a fertiliser, the simplest form of recycling is the present practice of spreading manure or sewage sludge onto agricultural land.

History of Phosphate Fertilizer • Early sources were mostly animal based ̶ bones, guano, manure • Treatment of bones with acid to increase P solubility started early to mid 1800s • Sulfuric acid treatment process of bones and P minerals (apatite) was patented in mid 1800s. • Today most P fertilizer .

These studies were undertaken to demonstrate the perform ance and reliability of a new, evaporative process for treatment of dilute, phosphatecontaining effluent. A large, pilotscale installation was built at Alcoa''s Warrick County, Indiana plant and tested on actual, phosphatecontaining effluent from aluminum coil cleaning operation.

A bismuth phosphate carrier precipitation process is patented for separating plutonium from fission products. Purification of plutonium is accomplished by precipitating bismuth phosphate in the presence of quadrivalent plutonium, thereby carrying plutonium from soluble fission products, and in another step precipitating bismuth phos phate in the presence of hexavalent plutonium, thereby ...

The EU imports an estimated 975,000 tons of phosphate fertilizers annually. This nonrenewable resource is mined in only a few locations, primarily the, China, Morocco and Western Sahara. Evaluation of the supply chain reveals that only 20 percent of mined phosphorus is actually consumed, with the balance lost in the process. Recovery from secondary sources is increasingly being ...

The manufacture of phosphoric acid is conventionally performed on a commercial scale by either the wet process or the thermal process. In the wet process, phosphate rock is treated with sulfuric acid to produce weak aqueous phosphoric acid (20 30% P 2 O 5) and calcium sulfate.
