Glatt Ingenieurtechnik: Pioneer in the East and in cutting-edge research
The plant engineering company Glatt Ingenieurtechnik is one of the most innovative companies in the East and conducts research into the materials and production processes of the future. (German article)
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. In cooperation with an industrial partner and the Material Research and Testing Institute of the Bauhaus University Weimar (MPFA) Glatt has developed a highly efficient process to extract phosphate from sewage sludge ashes, which is then converted into residue-free, ready-to-use standard fertilizers using fluidized bed spray granulation.
Jan Kirchhof, Glatt Ingenieurtechnik, Germany, presents a recovery technology that releases phosphate from sewage sludge ashes and converts it into ready-to-use 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. 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.
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. 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. 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)
In its current issue, the eastern German business magazine WIRTSCHAFT+MARKT presents 150 of the most innovative eastern German companies from seven sectors. 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.
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)
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)
