The Envirotank Clereflo™ range of oil water separators fully comply with the European standard BSEN-858.1.2002 and have been independently third party certified by British Standards Inc. and UNISA here in Australia.
The Clereflo™ range are full retention separators and will not discharge contaminates to the stormwater system in a hi flow or flood situation and are sized to contain more than the anticipated maximum oil spillage enabling them to be fully operational in always treating stormwater runoff, even in an emergency release situation.
They all come with a coalescing filter unit that incorporates an automatic closure device specifically designed to prevent any release of light hydrocarbons from entering the stormwater system. The automatic closure device (ACD) is also protected by the coalescer filter from being interfered with by silt, solids and other organic or introduced rubbish, thereby making the ACD 100% reliable in an emergency spill situation.
All third party testing results confirm that Clereflo™ oil water separators achieve a water discharge quality of less than 5mg/litre of light hydrocarbons in full compliance with European Standard BS EN 858.1.2002 and are available in treatable flow rates that range from 6LPS to 200LPS.
Class 1 separators are designed to achieve a discharge concentration of less than 5mg/l of light hydrocarbons in typical conditions. This class of separators are designed for discharging direct to stormwater drains and the environment.
Envirotank Clereflo™ Gravity Separator types:
Full Retention Separators
Forecourt or Under Canopy Separators
By Pass Separators
All Clereflo Gravity Separators are Full Retention and all liquid is treated. There is no by-pass possible.
All Clereflo Gravity Separators incorporate a coalescing process for the separation of smaller globular light hydrocarbons thus reducing the light hydrocarbon content in the outlet to less than 5mg per litre. The incorporated Automatic Closure Device (ACD) is sensitive to any change in water density and prevents any discharge as a consequence of light hydrocarbon build up within the unit. The ACD will automatically activate to shut off the separator outlet, preventing pollutants from discharging to drains and waterways.
The inlet is full length providing a wet seal & flame trap preventing a vapour path back to hazardous areas and no chance of a back-flow event in an extreme weather event.
Every Clereflo Gravity Separator also removes total suspended solids (TSS), silt, sediments and gross pollutants from the stormwater stream.
All Clereflo Gravity Separators will function in the event of power failure and can be retrofitted into existing or new drainage systems.
Maintenance is easy and safe, with no entering of the tank required to remove contaminants and silts.
