NEFCO Fiberglass Weirs and Scum Baffles

Weirs and scum baffles are the ever-present nuts and bolts of the treatment plant, where the versatility and durability of fiberglass makes it the material of choice for this equipment.


NEFCO can meet a wide variety of weir requirements including virtually any size and shape V-notch, rectangular or sharp-crested effluent weir. Weir plates are available in several thicknesses and in lengths up to twelve feet. These long lengths mean fewer splice plates and reduced installation time. Custom lengths up to twenty feet can also be provided. Weirs are supplied complete with weir washers, splice plates and stainless steel fasteners. NEFCO supplies Isophthalic Polyester (Type I), Vinyl Ester (Type II) and NSF 61 weirs and scum baffles.

Scum Baffles

Scum baffles are available as straight edge panels in a variety of widths ranging from 6″ to 48″ and lengths to twenty feet. For additional rigidity, a 12″ scum baffle with ¾” return flanges at the top and bottom is available. Scum baffles are supplied complete with splice plates, scum baffle brackets and all of the required stainless steel anchors and fasteners. Several types of baffle brackets are available to suit different application requirements.
