OVIVO® DuetTM Screen

With increasing popularity of finer screening to protect sensitive processes such as MBR systems, plants have been putting in two-stage fine screens. While this approach is beneficial to protect downstream equipment, it can be costly. In order to achieve the same benefit while minimizing the size and cost of the inlet works system, Ovivo offers the Ovivo® Duet™ screen. Our dual aperture drum screen, which combines a 3mm fine screen with a much finer mesh screen of 300-1800 microns, is essentially two screens in one. No coarse screens are required, and with a smaller footprint and lower operating costs, the Duet™ is ideal for finer screening applications.
  • 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 of the plant. The Ovivo® Duet™ dual aperture screen makes space efficient very fine screening available at a very 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 damaging large debris
  • Eliminate small fibrous inorganic waste that would otherwise foul your downstream process equipment
  • Lower plant operational costs

By combining two screens and grit removal in 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 is removing 1 ton of debris for every 1 million gallons treated more than what is removed with a similarly sized 2mm slotted rotary drum screen.

Screenings debris removed are reported as much as 4 times what was previously removed with a 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 flow through screen which is designed with less than 4″ of head loss. Rotary drum screens typically require a side influent with bottom discharge which requires a pumped flow. The Ovivo Duet screen can also be used without coarse screens upstream in most cases.

Is the Ovivo Duet dual aperture expensive?

The Ovivo Duet dual aperture screen is competitively priced and less than the cost of the two screens it takes the place of. 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. Seals, motors, washwater solenoid and the drive pinnion should require minimal service. The drive bearings require occassional grease. Ovivo service contracts are also available.

I like this screen, but don’t like “New” products until they are well proven

The first full size unit has been operating since March of 2012 with very little maintenance. All of the components used come from our other well proven Brackett Green® products. The drive system has been used for over 18 years, The spray wash system, Propapanel technology, and rollers all have proven to be long lasting reliable components of our center flow screens. Only the configuration is new.
