Parking Lot Stormwater Runoff Separator
The basic unit measures 34"wide 48" long 3" high. The low profile unit
measures 2"high with heavy duty steel construction, which is paint-powder coat.
Some of the advantages of the apparatus include: above ground installation and
drive over capacity 80,000 pounds or more. The design of the unit can be modified
for use as a walkways, speed bumps, berms, electric wire protectors, barriers, etc.
The water runoff and waste product separator includes a plurality of plate gussets which support a top cover plate. Each gusset has opposite ends with an interconnecting declining edge extending from the top plate to the roadway. The respective edges further support a first ramp and a second ramp. Each ramp includes elongated slots so that onrushing waste water flows through the first ramp followed by discharge through the slots of the second ramp. Collection sections are under the top cover plate and in the path of the oncoming rush of waste water and each section includes an oil absorption unit and a toxic waste or product unit so that the waste water must filter through these units to reach a discharge ramp. The units serve as a catch basin for retaining trash.
Therefore, it is among the primary objects of the present invention to provide a novel separator apparatus for use in parking lots and on a roadway for processing waste water so as to remove contaminants such as petroleum products, toxic materials or solid waste from waste water or the like.
Another object of the stormwater runoff separator is to provide an oil, petroleum product and hydrocarbon absorption and toxic material filtering unit which is carried in an apparatus positioned in parking lots and on a roadway in the line of traffic which will readily accept drainage or waste water in order to remove oil and toxic materials, therefore permitting discharge of relatively clean water.
Ponding behind the apparatus can be adjusted to meet the needs of application, set by property owner or manager. Stokes Law water retained 10 minutes or more will facilitate the settling out of the suspended solids. The ponding is controlled by the filter media. Sheen on the water will show up at 5 ppm while the suspended solids retain a large amount of contaminates. The filter media used and placement of controls the water flow. The use of PRP encapsulated in polypropylene will facilitate a grater range of remediation and water flow control. No hazmat disposal is a significant cost savings. |
