FRP Troughs manufactured by EDGENG® are designed for use in water and wastewater treatment plants. They are fabricated to ANSI / AWWA F101-96 Standards and are UL Classified for drinking water system components.
Typically, they are used either as Wash Troughs in the backwashing of gravity filters or as Collection Troughs (Launders) in structures such as clarifiers and settling basins. EDGENG® Fiberglass Troughs are available in a wide variety of widths and depths with round or flat bottoms. They can be molded in a circular configuration to mount against a round tank wall or inboard from the tank wall to double the weir footage. We provide V-notched or Straight edge Weirs, Splice Plates and support brackets as required. |
