With “PHOS4green” Glatt presents a new two-stage method that extracts phosphorus from sewage sludge ashes and converts it into ready-to-use fertilizer granulates
Jan Kirchhof, Glatt Ingenieurtechnik, Germany, presents a recovery technology that releases phosphate from sewage sludge ashes and converts it into ready-to-use fertilizers
The DWA Technical Committee KEK-3 for “Thermal Sewage Sludge Treatment” deals with the experiences and developments of thermal sewage sludge treatment in plants for mono- and co-incineration and the utilization or disposal of the resulting ashes.
During the meeting of the technical committee on April 03, 2019 in Weimar, Jan Kirchhof, Senior Sales Manager Process & Plant Engineering, Glatt Ingenieurtechnik GmbH, presented PHOS4green as an innovative solution for phosphorus recovery from sewage sludge ash and its residue-free conversion into ready-to-use phosphate standard fertilizers.
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. This results in fertiliser granulates that are available to plants and soil, which can be discharged, filled and delivered directly after the desired grain size has been reached.
From improving durability and flowability through dust reduction to a pronounced depot effect or a targeted nutrient supply via better active ingredient distribution, fluidised bed technology can deliver many benefits. The shape and size of the fertilizer granules can be determined within a defined range. The quantity of fertilizer components delivered to the soil can be adapted optimally, and significantly higher product qualities can be achieved. Solubility and protection against external influences can also be markedly improved.
Hot one-pot process – high temperature fluidized bed for simultaneous particle formulation and functionalization.
The requirements for the high-performance materials of the future pose new challenges for product developers: Innovative applications require increasingly complex materials, but their desired properties can so far only be achieved in cost-intensive multi-step processes. The process temperature plays a key role here. With high-temperature fluid bed systems, plant manufacturer Glatt overcomes previously applicable temperature limits and enables the production of catalyst materials in a single-step process.

Particles in an onion look – drying of liquids by fluid bed spray granulation. If liquid starting products are to be converted into bulk materials, both the spray drying and fluid bed spray granulation processes are used. The choice of technology depends on which particle properties need to be set to enable specific applications. (German article)
Phosphorus recovery on the agenda at the Landesverband der Recyclingwirtschaft Sachsen e. V. (State Association of the Recycling Industry Saxony) on November 13, 2018 in Leipzig. “High-performance fertilizer from sewage sludge ash”: this was the title of a presentation by Jan Kirchhof, Senior Sales Manager Process & Plant Engineering, Glatt Ingenieurtechnik GmbH, Weimar, as part of the program on “Phosphorus Recycling – Opportunities and Challenges in Saxony”.
The amended Sewage Sludge Ordinance gradually restricts direct agricultural utilization and requires operators of large sewage treatment plants to recover the phosphate bound in sewage sludge and ashes. A new approach makes it possible to fully recycle sewage sludge ashes and make the phosphate available for standard and compound fertilizers. (article in German language)
