Geoceptor - Bypass Separator
Bypass separators are installed and used when it is considered an acceptable risk to not provide full treatment for very high flows, such as where the risk of a large spillage and heavy rainfall occurring at the same time is small.
The Geoceptors unique bypass design is tested and proven to remove hydrocarbons, silts and solids from low flow surface runoff’s, preventing contamination of the surrounding environment.
There are four models in the range, designed to treat the run off from drainage areas of up to 22,220 m².
Each model features a robust HDPE body with a patented vertical separation system, designed for rainfall intensities of up to 6.5 mm per hour.
Where are Hydrocarbon/Oil Separators required?
Any site where there is a risk of surface water being contaminated by hydrocarbons including oils need to have measures in place to prevent pollution of the environment. Hydrocarbon /Oil separators are installed on sites where there is a risk of accidental spillages or leaks of oil from vehicles or plant and machinery. Under current legislation it is mandatory throughout the UK to prevent pollution and each site will need to consider the most appropriate measures required.
There are typically 2 types of Hydrocarbon/Oil Separator:
- Full Retention
- Bypass
Applications where Bypass Separators are installed:
- Car parks with 50 or more car parking spaces or larger than 800m²
- Smaller car parks discharging to environmentally sensitive areas
- Highways and roads
- Car wash bays
- Light industrial yards
Optional Accessories:
- Invert Risers (effective height of 230mm)
- High level hydrocarbon alarm
