The Clereflo™ range of oil separators from Envirotank are fully comply with the European standard BSEN-858.1.2002 and are third party certified by British Standards Inc. to effectively separate oil and water. They are full retention separators that will not discharge contaminates to the stormwater system. They are sized to contain more than the anticipated maximum oil spillage enabling them to be fully operational in treating stormwater runoff at all times, even in an emergency release situation. They all come with a coalescing unit that incorporates an automatic closure device specifically designed to prevent an emergency release of light hydrocarbons entering the stormwater system, thereby making it suitable for any hydrocarbon storage application.
They achieve a water discharge quality of less than 5mg/litre of light hydrocarbons, complying with European Standard BS EN 858.1.2002 and come in treatable flow rates that range from 6LPS to 200LPS.
Class 1 separators are designed to achieve a concentration of less than 5mg/l of oil under standard test conditions. These separators are required for discharges to stormwater drains and the environment.
Clereflo Gravity Separators by Envirotank are available as Full Retention Separators, Forecourt or Under Canopy Separators and 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.
