We design, supply and operate sewage sludge treatment systems.
We build and operate plants for the mechanical dewatering of sludge from wastewater treatment using exclusively state-of-the-art technology. Sostelia boasts the world’s most advanced patented sludge dewatering technologies, VOLUTE and VOLUTE DUO: energy-efficient, Industry 5.0 compatible, mobile ring systems for the treatment of greasy and oily sludge.
Customisation is our strength: we take sludge samples upon which we perform on-site and laboratory tests. We offer our customers the best performing plant and/or chemical solution for mechanical sludge dewatering with VOLUTE screw press technology based on the results of the sludge characterisation.
Our advanced VOLUTE DUO technology is based on the simultaneous operation of two independent screws with a self-cleaning system with separately actuated moving rings, which do not come into contact with each other, thus drastically reducing the wear rate and operating costs.
All screw press models in the VOLUTE range are designed to operate 24 hours a day, 7 days a week, in complete autonomy, without the need for supervision.
VOLUTE has an automatic cleaning system for the filter surfaces: this is a fundamental aspect for maintaining the best operational efficiency and rationalising the consumption of water used for washing.
The VOLUTE screw press, which allows access to the benefits of the 5.0 plan, ensures the reduction of electricity and water consumption, with positive impacts on noise and disposal and maintenance costs.
Sostelia guarantees solutions that significantly reduce sludge volumes, with capture rates exceeding 90% and no clogging. Our plants allow us to contribute to a circular economy and address modern water treatment challenges with efficiency and innovation.
We offer durable systems with simplified maintenance and guaranteed operational continuity. All of our solutions can be adapted to different types of sludge, waste and plant configurations.
It is possible to maximise water recovery, promote the careful disposal of pollutants and optimise the sludge treatment process by installing Sostelia’s solutions. These added values and tangible actions return water to its natural environment and reduce the environmental impact of companies and public bodies.
We support industries and companies in reducing water consumption and promoting recovery in production processes by providing state-of-the-art technologies that are entirely designed, built and operated by our Group.
We support integrated water service operators with tailor-made services and innovative facilities to purify water before returning it to its natural environment.
Our Group offers environmental remediation and groundwater treatment to recover contaminated sites.
We provide technical assistance, scheduled and predictive maintenance and emergency services for our customers.
