Rotary Fan Press™

Rotary Fan Press™

Here’s how the Rotary Fan Press™ by Prime works:

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.

The One And Only

The only dewatering device with patented screen technology that uses simple pressure differential and friction resistance to provide superior dewatering performance at a lower cost and prolonged service life. The totally enclosed dewatering process has slow operation speeds of less than 1 rpm, minimal wear parts, produces high cakes solids and excellent filtrate. Low operational costs, minimal or no manpower required, and low energy and water use provide savings year over year. Models are available in several sizes ranging up to 260 gpm hydraulically, in a small footprint, and most models have the ability to accommodate additional channels for future increased throughput requirements.

SIMPLE AND EFFECTIVE

  • Patented screen technology and fundamental physics.
  • Friction and pressure to force liquid out the path of least resistance.
  • Conditioned sludge is fed into the dewatering channel between two slow moving (less than 1 rpm ) parallel stainless steel filter screens.
  • Friction intensifies as the solids compress against the filter screens, causing liquid to take the path of least resistance and drain through the screens.
  • The remaining solids collect in the annular space between the filter screens and advance towards the discharge end of the press.

PRIME ROTARY FAN PRESS® 2.0 (patented)

Revolutionary. All the benefits of the original Rotary Fan Press™, plus:

  • Designed for sludge that releases moisture at a slower rate
  • Ultra-advanced, simplified low-shear dewatering device with a patented internal mixing element
  • Drier cake solids with higher throughputs at a lower cost.

The Prime Rotary Fan Press® 2.0 was designed for sludge that releases moisture at a slower rate. This ultra-advanced, simplified low-shear dewatering device with a patented internal mixing element will give you drier cake solids with higher throughputs at a lower cost.

PRIME ROTARY FAN SCREW PRESS® (patent pending)

The best of both worlds. All of the benefits of the original Rotary Fan Press™ coupled with the benefits of a screw press, results:

  • Higher throughput and cake solids in a smaller footprint.

The Prime Rotary Fan Screw Press® is ideal if you need larger throughput in a smaller space. The RFSP uses the same reliable technology of the Prime Rotary Fan Press® , with the added technology of an additional compression zone and screw press technology. It’s the best of both worlds.
