With the growing popularity of finer screening to protect sensitive processes and downstream equipment, plants been installing two-stage fine screens. While this approach is beneficial, it can be costly. Ovivo® offers the ideal solution. The smaller footprint and lower operating costs of the dual aperture Duet™ screen combines a 6mm/5mm/3mm fine screen with a much finer mesh screen ranging from 0.5mm, 1.0mm, and 2.0mm, essentially making it two screens in one, thus eliminating the need for coarse screens.
  • Two screens in one, plus grit removal
  • High capture efficiency
  • Lower operational costs
  • Flow through design

Many treatment processes can benefit from better screening at the front end of the plant flowsheet. The Ovivo® Duet™ dual aperture screen provides efficient, small footprint, very fine screening at an extremely affordable price. Additionally, existing process operations can be improved by adding this screen to the process to reduce debris build ups within the process.

  • Eliminate small fibrous inorganic waste that would otherwise foul your downstream process equipment
  • Lower plant operational costs

By combining two screens and grit removal into one package, the installed cost and required space is greatly reduced. Removal of large aggressive debris with our patented and proven Propapanel® technology, followed by removal of small fibrous waste reduces fouling, damage, and maintenance on downstream equipment.

 

Improved Inorganic Waste Removal

The Ovivo® Duet™ dual aperture screen removes one ton of debris for every one million gallons treated – up to 4 times more than what is reportedly removed with a similarly sized, 2mm slotted rotary drum screen.

 

How does the Ovivo Duet™ dual aperture screen differ from a rotary drum screen?
The Ovivo Duet dual aperture screen is a through flow screen which is designed with less than 4″ of head loss. Rotary drum screens typically require a side influent with bottom discharge that requires a pumped flow. The Ovivo Duet screen can also be used upstream without coarse screens in most cases.

 

Is the Ovivo Duet dual aperture expensive?
The Ovivo Duet dual aperture screen is competitively priced and costs less than the two screens it replaces. When compared to the installed costs of comparable alternatives, this screen is much more cost effective.

 

Does this screen require a lot of maintenance?
The Ovivo Duet dual aperture screen is very easy to maintain. The screen was designed for a long life, with only a few wearable parts. Occasional replacement of the second stage mesh, rollers and spray nozzles should be expected and the drive bearings require grease periodically. Seals, motors, the washwater solenoid and the drive pinion should require minimal service. Ovivo service contracts are also available.

 

I like this screen, but don’t like “new” products until they are well-proven. How would you address this concern?
The components of the Duet screen have all been tested and proven in our other Brackett Green®  products. Our Duet drive system has been used in other screens for over 18 years with great success. The spray wash system, Propapanel® technology and rollers are the same long-lasting, reliable components of our center flow screens, it is only the configuration that is new. The first, full size Duet unit has been in operation since March of 2012 with very little maintenance.
