When biosolids enter the system, pressure increases as waste moves slowly through a tapered channel. Friction intensifies as the biosolids compress against two rotating filter screens. Filtrate takes the path of least resistance and drains through the screens.
The dryness of the resulting biosolid cakes varies per application, but averages between 18–24 percent, with some applications achieving as high as 60 percent. In other words: Friction and pressure work together to create high percentage cake solids.
When You Need Dewatering Within a Small Foot Print
The compact, slow moving, quiet design of the Rotary Fan Press™ integrates easily into any facility, requiring no structural building modifications. Continuous dewatering within enclosed vertical dewatering channels makes it the dewatering system with the highest throughput per area of floor space required. Whether you chose our free-standing system, a skid mounted system or mobile dewatering system; the Rotary Fan Press™ by Prime is the simplest technology for dewatering performance.
