Floating Baffles

Floating Baffles

Floating baffles, also known as diversion baffles, lagoon baffles or water baffles are impervious floating curtain designed to create a hydraulic barrier in aquatic systems and improving overall water quality.

They’re designed incorporating gradients to create a complete floating barrier to promote settling from increased retention time and adjusted flow pattern. Promoting water quality by reducing the number of suspended solids in the water.

Typically used in water treatment ponds as part of the treatment process baffles control the flow pattern and change particle distribution by directing water flow in an alternate direction and motion to what would normally occur.

Trade Enviro supply closed cell foam baffles for shorter terms deployments and external float systems depending upon applications and project demand. We can assess your application and guide you through the process so call us today.

Trade Enviro design supply and install baffles if you’re requiring a turnkey solution on your next project.

The typical water flow is disrupted by the baffles, forcing the water to work harder and travel further to reach the discharge point as opposed to a natural environment below:

  1. What if there is a gradient on the embankment?
    The gradient is measured and shaped into the baffle so it fits tightly to the embankment without creating an overlap in the baffle. Anchoring assures the baffle remains located on the slope and a short circuit in direction does not occur. Short circuiting is when the water cuts its way through the baffle creating a short circuit in the design flow.
  2. How do I anchor this baffle?
    There are many ways to anchor a floating Baffle. First establish if you can use a cable system or an anchor system. Cables systems allow tension increase as required and are likely to be optimal in most applications. Use of cables allows adjustment and increase efficiency during maintenance. Weighted anchors require a lot more manual work and need to be suitable to harsh environments e.g. being submerged in waste water for prolonged periods. Weighted anchors need to be strategically placed to ensure the floating baffle retains its shape to work optimally and efficiently for its life cycle. Maintenance and management will be required.
  3. How long should I make my baffle?

  4. Do I need to service it?
    Servicing the floating baffle prolongs integrity and lifespan and is advisable for long term situations. Ensure hardware is clean from algae and slime, make sure the skirt is not heavily fouled. Fouled skirts increase ballast.
  5. What management does it take?
    Your plant and operations managers should be keeping an eye on the floating baffle system. Visual checks to ensure tension and close visual inspections for fouling are important first steps to an effective floating baffle system. Extreme weather conditions can seriously affect a baffle. Care needs to be taken in the event of extreme weather.
  6. How long does it take to make them?
    Baffles are made to order. Lead times from 10 days for orders less than 240 mtrs. Custom solutions and heavy duty requirements are subject to materials.
  7. How do you Freight them?
    Trade Enviro can ship you baffles on two way pallets suitable for a fork lift. Baffles packages with Anchor kits come complete with instructions and methodology statements for installation.
