Debris Filter

Beaudrey Debris Filter


Debris filters are used to protect condensers, heat exchangers and cooling towers from macro-fouling. Beaudrey debris filters are designed to remove organic and inorganic debris such as clams, shells, mussels, seaweed, pebbles, twigs, plastic, or debris that may be caused by marine growth in the circulating water piping. All debris filters are equipped with Beaudrey's patented NoCling™ technology, making them the best solution to preventing residual fibrous build up and jelly fish impingement.


Solution: W Type Debris Filter

Beaudrey has over 75 years of experience in the design and manufacturing of debris filters and has successful installations in over 42 countries. Beaudrey Debris Filters are designed to remove any debris that may pass through the intake screens. They can also remove any debris caused by marine growth in the circulating water piping.

Efficient backwash allows the debris filter to handle a multitude of debris types including clams, shells, mussels, fish, seaweed, concrete chips, pebbles and twigs. Beaudrey debris filters are equipped with the patented NoCling™ anti-fiber screening panels which are the best solution to preventing residual, fibrous build-up and jellyfish impingement.

Problem: Macro-Fouling

Macro-fouling is a problem in any cooling water intake system that draws water directly from natural water sources (rivers, lakes, coastal seas, oceans, etc). Macro-fouling is caused by the build-up of various matters (organic and man-made) found in intake water such as leaves, seaweed, branches, marine organisms, plastics, trash, etc. This matter obstructs the tube sheet of the condenser or heat exchangers causing circulating water flow restrictions, tube damage and loss of efficiency.

Large shell-forming organisms, such as oysters, mussels, clams, and barnacles can also exacerbate the macro-fouling problems. These types of organisms release free-swimming larvae that are very small and can easily pass through various intake screens. They then settle throughout the intake system and grow into maturity. Once the adult shell organisms die, their shells remain attached to the intake systems and can eventually break loose clogging condenser tubes and other small openings in the water screening system. Cooling systems provide ideal conditions for the growth of these organisms. The cooling water pumps maintain a steady flow of water that carries nutrients and provides an ample food supply. In some geographic areas, the organisms may be able to grow and reproduce all year long.

Closed loop systems that draw water from lakes, ponds and reservoirs also suffer from the problem of macro-fouling. Systems using cooling towers suffer from nozzle plugging resulting in loss of cooling efficiency.

How it Works

Beaudrey industrial water filters are typically installed downstream from the circulating water pump before the inlet of the heat exchanger or condenser. The debris filter consists of a rotating screen installed inside of a spool piece in the cooling water piping. As debris collects on the screen and differential pressure across the screen rises, it begins to rotate removing debris through backwashing. The collected debris is then bypassed downstream from the heat exchangers or condensers and discharged into the outflow.

Similarly, in closed loop systems, Beaudrey debris filters are typically used to screen water upstream from the cooling towers, bypassing any debris that could potentially plug cooling tower spray nozzles.

Value Creating Advantages

  • Backed by nearly 100 years experience and over 800 debris filters installed world-wide, Beaudrey is a market leader in water screening solutions
  • Innovative engineering designs prevent lubricants from being released or leaked from the debris filter into the environment
  • The debris filter is compact and easy to install in piping systems with complex geometry and tight spaces
  • Guaranteed lowest head loss of debris filters on the market
  • The debris filter is based on the Beaudrey “W” design principle, allowing for spare part interchangeability with the Zero Ball Loss (ZBL) condenser tube cleaning system and Water Intake Protection Screen (WIP). This reduces the spare parts inventory required
  • The filter is designed to be bi-directional in rotation creating greater operational flexibility
  • Low, hassle-free maintenance: a complete overhaul of the debris filter can be completed in one shift and all drive-related items are accessible from the outside. Additionally, there are no moving parts that may be jammed by the debris that is filtered
