Stormceptor Has Broken Down Their Units Into the Following Categories

Manufacturer: Imbrium

Product: Stormceptor

Head Loss

The measured head loss through the Stormceptor is approximately equal to a 60 degree bend at a manhole. An appropriate K value to use in calculating minor losses through the storm drain system for a Stormceptor unit would be 1.e (Minor Loss = 1.3 v2/2g)

Stormceptor has broken down their units into the following categories:

• STC
• EOS – Extended Oil Storage System; hydrocarbon spill protection
• OSR – Oil & Sand Removal; designed to remove fine sand particles at the peak flow rates regulated by jurisdictions
• MAX- for large-scale industrial and residential areas which may require a single stormwater management device

STC- has been divided into four categories

• Inlet Stormceptor – a standard design for most stormwater treatment applications
• Inline Stormceptor – designed to direct stormwater into the unit through a grated inlet. Ideal for small parking lots, loading bays, gas stations and other spill prone areas
• Submerged Stormceptor – designed to treat stormwater in submerged pipes. Ideal for coastal areas with standing water.
• Series Stormceptor – designed to treat larger areas, two adjacent Stormceptor models function in parallel.

Inlet Stormceptor

Model STC 450i only

The Inlet Stormceptor takes the place of a traditional inlet structure in a storm sewer system. The Inlet Stormceptor is designed to replace a catch basin, featuring an open grate at the surface. It is ideal for small drainage areas including truck loading bays, electrical transformer stations and vehicle refueling stations. The Inlet Stormceptor is a 48” diameter precast concrete structure with a patented fiberglass insert. The insert extends into the treatment chamber, providing dual wall containment of hydrocarbons.

During infrequent high flow events, storm water flows over the diverting weir into the downstream sewer system, preventing scouring of previously trapped pollutants. The high flow by-pass prevents previously collected pollutants from scour and re-suspension.

Inline Stormceptor

STC Models 900, 1200, 1800, 2400, 3600, 4800, 6000, 7200

During infrequent high flow events, peak stormwater flows over the diverting weir and continue into the downstream storm sewer system. This by-pass activity creates pressure equalization across the by-pass chamber, preventing scouring and resuspension of previously trapped pollutants. Stormceptor claims that it is the only device with an internal by-pass that prevents scouring of trapped pollutants. The device is constructed from precast concrete components and a patented fiberglass insert.

Submerged Stormceptor

STC Models 900, 1200, 1800, 2400, 3600, 4800, 6000, 7200

The Submerged Stormceptor system removes total suspended solids, free oil, and other pollutants from storm water runoff in partially submerged pipes. During infrequent high flow events, water is conveyed over the internal bypass weir directly to the downstream storm sewer. This bypass activity prevents high velocities of water from entering the treatment chamber.

The precast sections are manufactured in easy to assemble components and are available in the same sizes as the In-Line Stormceptor. A customized weir separates the upper (bypass) and lower (treatment) chambers.

Extended weir and second drop tee height are custom designed based on tall water elevation.

Height of weir corresponds to the difference of outlet invert and tall water elevation.

Weir can be extended to a maximum of 45 inches from the outlet elevation (including the existing weir)

Series Stormceptor

STC Model 11000, 13000, 16000

Designed to treat run-off from larger drainage areas, the Series Stormceptor can more than double the treated drainage area of the In-Line Stormceptor System. During infrequent high flow events, peak stormwater flows will pass over the diverting weirs in the first and second chamber and continue through the bypass chamber into the downstream sewer system. This bypass activity creates pressure equalization across both units, preventing scouring. A portion of incoming sediment continues to be diverted by the weirs in the first and second structure into the treatment chamber.

Two 8’ diameter upper by pass structures

Two 10’ or 12’ diameter treatment chambers

Inlets and outlet of upstream structure must be 180 degrees

Minimum direction change from inlet to outlet of downstream structure is 90 degrees

Joining weir must be installed between both units

Frame and covers orientated to over riser pipes and oil ports in both units.

Sump Depth

EOS – Extended Oil Storage System

The EOS model features increased storage volume for safe oil containment comparted to standard Stormceptor models

Creates a non-turbulent treatment environment allowing oil to rise and sediment to settle

Patented scour prevention technology ensures captured oil and sediment remain in unit for secure storage and easy removal

Ideal for gas stations, airports, garages, loading docks, high collision intersections and other spill prone areas.

Existing Stormceptor units can be retrofitted to become EOS Models.

OSR – Oil & Sand Removal

THE OSR Model is designed to remove fine sand particles at the peak flow rates. Units are easily sized used NJCAT verified and NJDEP interim certified flow rates

Slows incoming stormwater to allow free oils to rise and fine sand particles to settle

Provides hydrocarbon spill protection in dry and wet weather

Easy installation – small footprint saves time and money with limited site interruption

Minimal drop between inlet and outlet pipes (one or three inch drop) and the unit can be used as a bend structure

Low head loss of nine inches for the OSR 250 from inlet to outlet makes it compatible with existing infrastructure.

Seamless support of existing BMP’s (wet/dry ponds, filtration and infiltration devices)

NJCAT CHARTS

Stormceptor MAX

The Stormceptor Max responds to the needs of large-scale industrial and residential areas which may require a single stormwater management device. It provides stormwater quality treatment for areas 20 to 100+ acres and industrial spill volume capture of 15,000 + gallons.

Increased sedimentation chamber extends horizontally rather than vertically

Non turbulent treatment environment allows oil to rise and sediment to settle

Industrial spill protection in dry and wet conditions

Patented scour prevention technology contains captured oil and sediment for secure storage and easy removal

Ideal for industrial or residential sites with established infrastructure

Modular and expandable, depending on the site’s size and water quality objective

Lower chamber can be constructed of different materials, depending on site conditions
