Baffles, Weirs, Launders, and Covers

Performing a wide array of functions, Weirs, Baffles, Launders, and Covers are integral parts of a wastewater treatment plant.  Whether to mitigate density currents, reduce scum carryover, separate zones in biological tanks, increase residence time for disinfection, reduce flow turbulence, etc., composite baffles are simple pieces of equipment that play an important role in the wastewater treatment process.


Covers are used often to prevent freezing in cold climates, or odors from otherwise open top tanks.  AFT carries a wide range of covers from full tank aluminum geodesic dome covers, walkable FRP tank covers, FRP launder covers, and aluminum and FRP channel covers.
