BMP SOLUTION
POLLUTION PROBLEM SOLVER
ABT Inc’s TrenchFormer FirstFlush® system is a cast-in-place stormwater channel that is designed specifically for sites under 100 acres where specific pollutants – oils, greases, and other hydrocarbons – must be captured without impeding bypass flow particularly during the first fifteen minutes of a rainfall or “first flush” effect.
Cast-in-place forming systems allow for greater flexibility for all your heavy-duty and high-volume applications including highways, airports, and anywhere you need quick and efficient drainage. FirstFlush® technology is perfect for sites that lack the necessary area for retention ponds and larger structures.
STORMWATER FILTRATION
FILTRATION MEDIA
FirstFlush® is the perfect solution when seeking a best management practice (BMP) that must handle sheet flow, control vectors, collect debris, treat bacteria, and capture hydrocarbons – all on the same site. The ABT FirstFlush® cast-in-place stormwater channels utilize a variety of filtration media and fabrics.
- Standard Filtration “Blankets”
- Antimicrobial Filtration Media
- Hydrocarbon Media
- HMR – Heavy Metals Removal Media
1640FF PRODUCT DATA – FIRSTFLUSH STORMWATER FILTRATION SYSTEMS
The FirstFlush 1640FF, our largest capacity design, uses ABT’s patented forming technology to create a highly durable concrete component. As effluent enters either through an inlet pipe or a trench drain, the first chamber captures solid debris. After passing through the sediment screen, effluent passes through two removable smart sponge filter panels before exiting. The pre-sloped bottom eliminates ponding, an excellent feature where vector control is an issue. The 1640FF is provided with solid covers.
