ADVANTAGES
- No clogging, even with oily sludge
- High solid capture rate
- Power-saving
- Water-saving
- Low noise and low vibration
- Easy operation and easy maintenance
- Small footprint
- Excellent expandability
The machine has a filter element (cylinder) that consists of alternating layers of Fixed Rings and Moving Rings, with spacers in between to maintain a gap that allows filtrate to escape. Inside the cylinder, a single screw conveys and subsequently pressurizes the sludge through the cylinder towards the end plate. As the screw rotates, it drives the moving rings up and down, which cleans the filtrate gap, creating a clog-free and self-cleaning mechanism. Only a very small amount of water at low pressure is periodically used to gently clean the rings from the outside. The design delivers stable thickening performance even with oily sludge.
Small footprint
This model can be installed in places where other types of thickeners would be difficult to install, such as in low-ceiling buildings or where a small footprint is required. This allows it to replace most existing thickeners, often while increasing the capacity. For instance, when comparing the VOLUTE™ to a belt-type thickener, both having a throughput of 30 m³/h, the footprint is about 1/3. Thickeners are also very suitable to replace sedimentation tanks, of which the footprint is another order of magnitude.
