Key Features
- Custom Shapes: Available as straight, circular or “finger” (notched) designs to fit round or square tanks.
- FRP Composite: High-strength fiberglass panels with UV-stable gelcoat.
- Adjustable Height: Some FRP weirs can be raised/lowered to fine-tune levels.
- Scum Baffle Integration: Often combined with FRP scum baffles to skim floating debris.
- Smooth Edges: Eliminates rough edges that could trap sludge.
Benefits
- Corrosion-Free Service: Unlike metal weirs, FRP does not pit or warp in water.
- Uniform Flow: Ensures even discharge around clarifier, improving settling.
- Simple Installation: Lightweight panels bolt onto tank wall or trough.
- Low Maintenance: No repainting; just periodic cleaning.
Applications
- Clarifier Perimeter Weirs: Control effluent levels in circular or rectangular clarifiers.
- Filter Distributors: Used atop filters to level flow entering underdrains.
- Clearwell Tanks: Weirs in potable water storage for mixing or overflow control.
- Chemical Baths: Edging on tank surfaces to direct fluid during process mixing.
Technical Specifications
- Material: FRP panels (e.g. 6–12 mm thick) with stiffening ribs if large.
- Widths/Length: Sized to match tank dimensions; multiple sections bolted end-to-end.
- Finish: Chemically resistant paint or gelcoat for life extension.
Unique Selling Points
- Design Options: Weir profiles can be customized to optimize hydraulic performance.
- Non-Corrosive: Maintains calibrated weir height even in chlorinated water.
- NSF-Approved: Can be made to NSF-61 potable water standards if required.
- Lightweight & Durable: Easy to handle modules with the lifespan of concrete.
