What is the Barracuda?
Single Structure Hydrodynamic Separator
Available now in 4’ diameter (1.25
cfs
NJCAT, 1.08 cfs 80% OK-110, 6.25
cfs MHR). 6’ unit available in January. 8’ unit in the spring.Extremely cost effectiveSlide4
Can be installed in a standard precast manhole.
4’ unit can be fabricated in a lightweight ADS HP manhole.
Quick turn around times – typically
3
weeks as opposed to 4-6 week
for precastSlide5

Why the “teeth”
High water turbulence disrupts particle separation and increases “
resuspension
” of captured material.
When
water flow passes by the solid body of the
"teeth", the flow contacts the body and a boundary layer forms along the body surface. The boundary layer thickens due to viscous diffusion, and is convected downstream until flow separates. Flow separation is subject to lift and drag forces from the angle of attack. The angled “teeth” also facilitate particle settling by increasing the settling surface area and reducing the settling distance. Slide8
Test Results
Third party test shows 80
% removal of OK-110 particle at
1.08
cfs
treatment flow rate.Testing per NJCAT show 50% removal at 1.25 cfs
(smaller particles size than OK-110)NJCAT resuspension testing shows 1 mg/l of resuspension at flow 2 x MFTRSlide9
Maintenance
Maintenance can be performed from the surface
No parts to remove, no need to enter the structure
Remove the frame and grate
Vac hose is lowered through 10” opening at the bottom of the BowlSlide10
