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

/in /by

In some regions, the departure from agricultural sewage sludge use is coming faster than the sewage sludge ordinance requires. This was demonstrated at the sewage sludge specialist forum held by the Huber company in Berching, where a good 300 participants discussed concepts for sewage sludge utilization, phosphorus recovery and inter-municipal cooperation.

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.

New waste-free process produces fertilizer from phosphorus-containing ashes

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.

Small quantities, big effect – Agglomerates from the fluid bed

Whether a fortified protein bar or an instant drink becomes a bestseller clearly depends on how well the powdered ingredients can be integrated into the recipes and consumed. Glatt’s compact plant concept now makes the advantages of property configuration by means of fluid bed technology economically viable for medium-sized productions as well.

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

/in , /by

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

/in /by

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)
