KOPF SynGas and SÜLZLE KLEIN at IFAT 2022

The SÜLZLE Group is well positioned as a specialist for integrated solutions for sludge treatment and resource-efficient heat and energy generation at the world’s leading trade fair IFAT in Munich. From 30 May to 3 June 2022, the water and energy experts will be offering future-oriented solutions at their stand 221/320 in Hall A2. SÜLZLE KLEIN and SÜLZLE KOPF SynGas cover the entire process of thickening, dewatering, drying, sewage sludge utilisation and energy recovery, as well as pollutant elimination. In addition, visitors to the exhibition stand will be able to immerse themselves in the world of drying and thermal sewage sludge utilisation for the first time with VR glasses.

Rosenfeld, 24 March 2022 – At this year’s IFAT, the world’s leading trade fair for environmental technologies, changing climate conditions are among the key challenges that the industry will have to tackle in the future. CO2 reduction and phosphorus recovery in sewage sludge disposal are major challenges, and not only for sewage treatment plant operators. “The energy transition has become one of the central challenges of our time. Through further developments and synergies within the group of companies, our future technologies enable optimised sewage sludge utilisation as part of the circular economy. In addition, the SynGas fuel gas module can secure sewage sludge as a secondary fuel in the long term,” explains Heinrich Sülzle, managing partner of the SÜLZLE Group.

Comprehensive sludge treatment
SÜLZLE KLEIN will present visitors to the trade fair with an extensive product portfolio for mechanical and thermal sewage sludge treatment. In addition to machines and systems such as the solidXfloc polymer station, the solidXdrain belt thickener and the Pro-Dry series of dryers, the focus will also be on a new product for sludge volume reduction.

‘Together with experienced specialists and our competent team, we will continue to expand our range of machines and systems and the services we offer our customers. Our aim is to offer our customers ideal solutions for thickening, dewatering and drying sewage sludge,’ says SÜLZLE KLEIN Managing Director Frank Scheidt.

The experts at SÜLZLE KLEIN will provide trade fair visitors from the municipal and industrial sludge treatment sectors with insights into current reference projects, such as the development and delivery of two belt filter presses and peripherals for a large steel manufacturer. The goal: environmentally friendly and largely automated blast furnace gas sludge dewatering. The technical challenges: a highly abrasive medium and high expectations in terms of availability. SÜLZLE KLEIN was able to meet both criteria with specially designed machine technology. The user opted for two solidXpress HD belt filter presses in combination with two solidXfloc polymer systems. The turnkey plant was completed with discharge conveyor belts, container loading and a control unit, including installation and commissioning. The new solidXpress HD belt filter presses round off SÜLZLE KLEIN’s portfolio of dewatering solutions for blast furnace gas sludge and are suitable for almost all areas of metallurgical and steelworks technology.

Thermal sewage sludge utilisation
SÜLZLE KOPF SynGas’ thermal sewage sludge utilisation is a flexible, future-proof process for the direct use of energy from sewage sludge. In a fluidised bed reactor, synthesis gas is first produced and then made flexibly available as an energy source in various modules.

Thanks to its compact design, the process can be easily integrated into existing operations. It meets the legal requirements for sewage sludge treatment, and the SynGas ash also complies with the legal requirements for phosphorus recovery. The latest reference plant in Koblenz was handed over to the customer at the end of 2021 and has since been operated by KOPF SynGas for the Koblenz municipal sewage system.

Replacing fossil fuels with sewage sludge
The SynGas fuel gas module solution is also aimed at power plants and cement works, for example, and contributes to the decarbonisation of industry. In order to recover phosphorus in the future, it is necessary to separate the material flows when recycling sewage sludge. This is where the module comes in: its integration into the existing infrastructure ensures that sewage sludge can continue to be accepted and recycled.

The combustible synthesis gas produced from the sewage sludge is available as a substitute fuel for flexible use in various combustion processes with exergy requirements. The phosphorus contained in the sewage sludge is separated together with the ash produced in the process and, if desired, sent for further recycling. Through phosphorus recovery, the process makes a valuable contribution to the circular economy and helps to reduce CO2 emissions.
