HELYX manufactures Helyx ZG high-efficiency drum screens, which are a modern type of screen that combines the process of filtering water, washing and dewatering retained waste. They are widely used for mechanical treatment of domestic wastewater, as well as wastewater from food, paper and other industries.
The drum screen is used to remove large debris and suspended solids from wastewater. Removal of large inclusions is achieved thanks to the rotation of the drum with the auger, and the automatic transfer of waste to the container.
They are used as part of treatment facilities for domestic and industrial wastewater.
Drum screens of the HELYX ZG type are a modern type of screens. The Auger Screen is a unique system that combines filtration, flushing, conveying, compaction and dewatering in one unit. The auger grate is installed directly into the channel or into a separate tank.
Waste water flows through the open front of the filter drum, through gaps or perforations, solids are retained on the drum, therefore, the filtration of floating, settling and suspended substances depends on the width of the gap or the size of the perforations.
A clogged grill surface creates an additional filtering effect. In this way, solid particles of a smaller size are captured than a hole or perforation. The unit starts operating when a certain water level is reached due to clogging of the surface in front of the grate. A robust stainless steel auger removes debris from the surface of the filter drum.
Additional cleaning is achieved thanks to wear-resistant brushes mounted on the auger coils. The auger conveyor directs the waste through a closed inclined pipe. During transport, the waste is dewatered and compacted before being discharged into the customer's container or downstream conveying device, without generating any unpleasant odor. Rinse water is drained into a channel behind the grate, and dewatered contamination is removed into a container.
