Brackett Green® Debris Filters

Brackett Green® Debris Filters Brackett Green® Debris Filters

Most power plants employ extensive pre-screening at cooling water intakes. Despite this, additional filtration can be required at locations where the cooling water is loaded with heavy debris and marine life. Brackett Green® debris filters provide a vital line of defense, efficiently intercepting and removing coarse particles, fibrous material, mussels, clams and other macrofouling related to problems downstream of pumps and preventing them from entering into the heat exchanger or condenser.

Further Details

Ovivo understands the importance of the thermal performance of your plant to ensure plant output, and ultimately, profitability. Online, self-flushing Brackett Green debris filters are an effective solution to minimize fouling from the condenser tubes. This last line of defense for your cooling water system can increase or maintain your condenser’s heat exchange rate by keeping the tubes clean, reducing operating costs and ultimately, your environmental footprint.

Key features & benefits

  • Compact design suitable for new installations or retrofit
  • Low pressure drop
  • External drive mechanism with easy access to seals and gear box
  • Suitable for high flows and a variety of filtration sizes 
  • Suitable for high debris loading and continuous operation
  • Can be manufactured to ASME, Nuclear and Power & Petrochemical Industry codes and standards
 

Prevents macrofouling

Built-up debris at the heat exchanger inlet and condenser tubes can stop or slow cooling water flow. This reduced the rate of cooling water through the tube which results in the reduction in heat transfer rate and overall plant efficiency and output. Debris build-up also shortens tube service life through corrosion, erosion and pitting.

Automatic debris filtering prevents macrofouling of heat exchangers and condensers, lengthening service life and eliminating an array of potential performance problems. These include: insufficient cooling, ineffective temperature control, increased pressure drops, high energy consumption and costly downtime.

 

Compact design handles all debris

Ordinary self-flushing debris filters are installed externally to the cooling water line, demanding a large amount of space and additional pipe work. Some are designed to handle coarse debris while others are more suitable for fibrous debris removal. Ovivo’s unique Brackett Green automatic, self-flushing debris filters fit within the cooling water piping and can handle all forms of debris.

The Brackett Green debris filter’s housing actually replaces a segment of the cooling water pipe work, requiring no additional space or connections. The filtration mechanism is designed to remove coarse as well as fibrous debris including plastic, mussels, clams, fish, tree roots, seaweed, algae, rocks, wood chips, pine cones and leaves.

 

Optimum performance for minimal cost

The Brackett Green debris filter’s unique design provides maximum debris removal at the lowest operating and maintenance cost. Ovivo Brackett Green debris filter incorporates an array of high efficiency features, including:

  • Low operating pressure drop across the debris filter
  • Maximum debris removal for minimum flush water discharge
  • No external water required for flushing
  • No external pump required for flushing or debris removal
