The advanced wastewater treatment processes that are employed in today’s plants require the capture of even finer material and are subject to blinding faster. As population rises, plants are also experiencing increased flows to plants without the option of an expanded footprint, further complicating the procurement process.
But now an easy-to-clean solution offers high throughput capacity and maximum separation efficiency, with plastic perforated screen elements to prevent hair pinning and fouling. HUBER Technology’s CenterMax Hybrid perforated band screen offers a center-flow perforated band screen with plastic perforated screen elements to address those challenges.
The CenterMax Hybrid offers a variety of screening elements and opening sizes tailored to meet the separation needs of the application, high capture of fine particles including fibers and hair, and ideal protection of sensitive processes including MBRs. Its inside-out flow design allows for the most screening surface area for any given channel. With easy access to service points at grade level, the technology is designed for narrow channels and high throughputs. In addition, its vertical design allows for it to be employed in small areas, limiting its footprint.
Available in perforations from 2 to 6 mm, the CenterMax Hybrid’s plastic perforated screen elements prevent hair pinning and fouling while providing effective element cleaning without a rotating brush. The baffle plates direct the wastewater flows into the center opening and out each side. Solids are retained on the inner surface of the screening elements, leading to gradual blinding of the screen surface. This blinding results in the water level in the channel rising. Cleaning of the filter elements starts when a predetermined water surface level is met. The drive unit rotates the filter elements carrying the screenings upwards and out of the channel. In the upper part of the screen a spray bar(s) and nozzles remove the solids from the surface of the screen elements and flush them into an internal trough. At this point the screens are discharge by gravity to be further processed.
“HUBER Technology is committed to providing high quality solutions resilient to the exposed elements of wastewater treatment,” says HUBER Technology President Henk-Jan van Ettekoven. “We’re proud to now offer the CenterMax Hybrid to better serve our customers with durable solutions for processes requiring high capture and high throughput.”
