ANDRITZ expands its range of C-Press screw presses for efficient dewatering

With its direct drive system and conical shaft with constant screw pitch, the C-Press screw press has now a feed capacity ranging from 1 to 95 m³/hr, with an outlet capacity from 20 to 1,300 kg DS/hr. In addition to a long lifecycle, the press also offers the advantages of easy operation, low maintenance, and – due to bi-sequential cleaning – 30% less water consumption than comparable equipment. Last but not least: the C-press complies with all regulations on such issues as safety, hygiene, and environmental protection.

The C-Press from ANDRITZ is a screw press providing state-of-the-art technology, high performance combined with compact design and featuring low operating costs in sludge dewatering processes. Furthermore, it offers simplified operation and processes free from contact with dewatered sludge, combined with low maintenance and energy consumption costs.

ANDRITZ product manager, Nicolas Perrier says: “The screw dewatering technology is the best solution from low to high flow ranges, as it has an excellent performance in terms of cake dewatering and filtrate quality. Furthermore, it has a very low noise level and an extremely low operating cost, as it operates at extremely low speeds. Due to these features, the C-Press has much lower energy consumption than other technologies and results in very low maintenance costs, leading to a very long life of the equipment.”

With a high-performance system, the C-Press maximizes the basket's open area, featuring high specific capacity and excellent capture rate, when compared to equivalent technologies. The screw speed is automatically adjusted, according to the input oscillation, ensuring a continuous flow with optimized performance in terms of drying and capture rate, even during the washing phases.

Nicolas Perrier concludes: “The equipment offers low consumption of water for washing. We do not need to stop the sludge feed to carry out washings, so we operate continuously with greater productivity. In addition, the latest developed model, the C12060, with an average dry solids throughput from 420 to 1,300 kg/h – one of the highest capacities on the market – the machine is an alternative to other large technologies for sludge dewatering, such as large belt presses, which are more energy-intensive and more demanding in terms of maintenance. In any case, ANDRITZ has the widest range on the market to meet the separation needs of customers in the environmental sector”.
