PHOS4green presented @ Sewage Sludge Technical Forum 2019 in Berching, Germany

In some regions, the departure from agricultural sewage sludge use is coming faster than the sewage sludge ordinance requires.

Jan Kirchhof, Glatt, presented PHOS4green as a solution for phosphorus recovery from sewage sludge ash and its residue-free conversion into commercially available standard fertilizers.

Meet the Glatt PHOS4green experts at the POWTECH 2019 Hall 3 / 3-249

Glatt Ingenieurtechnik will be presenting a market-ready process at POWTECH that fulfils the legal obligation of German waste disposal companies to recover phosphorus. In the first step of the two-stage “PHOS4green” process, a suspension is produced from the phosphate-containing ash, a mineral acid and, depending on the objective, other components. The suspension is then spray granulated in the fluidised bed.
