PHOS4green presented at the DWA Conference 2019 in Weimar, Germany
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.
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. 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.
Formulation For Success – Fluid Bed Systemes as Key for the Production of Speciality Fertilizers
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
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. With high-temperature fluid bed systems, plant manufacturer Glatt overcomes previously applicable temperature limits. (German article)
Particles in an onion look – Drying of liquids by fluid bed spray granulation
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)

These include mechanical engineering, the mobility sector, the IT and digital economy, energy and environmental technology, the healthcare industry, the chemical and plastics industry, and the food and agricultural industry.
Dried to the point – Thermal processes in the fluid bed
Fluid bed technologies are ideally suited for carrying out heat and mass transfer processes, which are in demand during drying. Particles can be simultaneously refined and functionalized economically in parallel with drying by means of spray granulation, spray coating or spray agglomeration. The selection of the right drying process is challenging: it depends on the prevailing conditions in each case and requires a holistic approach. (article in German language)
Twelve days installation time – Compact system for continuous spray agglomeration of fine powders
Powder agglomeration compactly solved: Protein shakes, capsule coffee and sugar substitutes must be able to be precisely dosed and dissolve quickly; they must neither lump nor segregate. By means of continuous spray agglomeration in the fluid bed, these properties can be precisely adjusted. The new GF ModFlex compact system from plant manufacturer Glatt Ingenieurtechnik makes this economically feasible even for medium-sized productions. (article in German language)
Fluidised bed processing – Added-value ingredients for better products
The properties of functional ingredients can be fine-tuned using fluidised bed spray granulation, agglomeration, microencapsulation and coating. At Health ingredients Europe, plant manufacturer Glatt Ingenieurtechnik will showcase a new compact spray agglomeration concept for industrial-scale continuous production.
