Abstract :
[en] In the PhosForYou project, the PASCH process, formerly designed to recover phosphorous from sewage-sludge incineration ash, is extended to start from dried sewage sludge directly. One of the major steps in this process is the reactive extraction of heavy metals from a leach liquor, followed by fractional precipitation. The process is realized on pilot-plant scale and tested in bypass at waste-water treatment plants. The process param-eters will be optimized to maximize process efficiency depending on the local situation with respect to impurities and water content. The product is a phosphate, which can directly be used in fertilizer formulations.
