FAQS

All our systems are individual solutions that are tailored to the exact requirements of our customers. The decisive factors for determining the right type of plant include: the size of the sewage treatment plant (amount of sludge produced), the available space and location (climatic conditions), the initial and the target DR content as well as any other local factors, customer requirements and the sludge logistics already in place.

Thermo-System plants will dry anything from liquid to highly dewatered sludge. Thanks to our many years of experience, in-house drying tests and research on a wide range of materials, we can adapt our plants to a large variety of parameters and conditions. We have a long track record of developing plants for many different materials to be dried.

The time required depends on the type of plant and varies greatly. Drying can take hours or months: In StorageDryer plants, for example, the dried sludge is only removed from the drying chamber once or twice a year, while thermal drying plants only take a few hours.

The final percentage of the sewage sludge solids content can range between 30% and 90% depending on your requirements.

Thanks to our sophisticated ClimaControl system, most plants can be operated without any kind of waste air treatment.

If the origin or quality of the sludge or the on-site conditions make it necessary or simply worthwhile to treat the exhaust air, Thermo-System offers a series of solutions that can be adapted to your specific situation and needs.

In contrast to sewage sludge humification, the end product of the StorageDryer system is dried throughout, making it a versatile fuel that contains no rhizomes or other foreign matter. The low levels of moisture residue in dried sludge and its greatly reduced volume ensure certainty in terms of both costs and disposal.

What makes both processes stand out is that they are based on continuous plant operation, which involves little working time. Compared to sewage sludge humification, however, the StorageDryer requires considerably less space. The StorageDryer is powered by solar energy – free of charge. Sustainability and eco-friendliness are the two exemplary pillars of this process.

Decentralised sludge drying is environmentally friendly and cost-effective, since its reduced haulage requirements save C0₂ emissions. In addition, it ensures greater independence from sludge buyers.
