This project required the collection and oil/water separation from a runway on a NZDF site. The area needed to collect all liquid with no by-pass operation with the flowrate from the catchment area at 500lps.
Due to the space requirement where 1x P500 tank wouldn’t fit, we designed 2x P250 units with a splitter manhole to divert the flow to the two tanks
The SPEL Puraceptor is a full retention separator that treat all flows. It is sized to contain more than the anticipated maximum oil spillage – enabling it to be fully operational in treating stormwater runoff at all times.
Puraceptor P250 Size: 2500OD x 17500mm
– Working Litre : 75.000
– Total Litre : 80,000
– Maximum Oil-Litres : 38.000
– Maximum Silt-Litres : 12,600
SPEL Puraceptor is a full retention oil/water separator that treats all flows. It is to be sized to contain more than the anticipated maximum oil spillage — enabling it to be fully operational in treating stormwater runoff at all times. It has two chambers, a coalescer and is fitted with an automatic closure device specifically designed to contain major oil spills, thereby making it suitable for high-risk applications. It achieves a water discharge quality of less than 5mg light liquids per litre, complying with European Standard BS EN 858.1. 2006 and exceeding ARC TP10. Treatable flow rates range from 2LPS to 200LPS. Pipe sizes range from 100mm to 450mm (larger sizes on request).
AUTOMATIC CLOSURE DEVICE. The Automatic Closure Device (A.C.D.) is precisely engineered to be sensitive to any change in water density, as a consequence of light liquids build up. This automatically activates a process of depressing the A.C.D. to shut off the separator, preventing pollutants from discharging to drains and waterways
FULL RETENTION. All liquid is treated. There is no by-pass operation.
COALESCER EQUIPPED. Provides a coalescing process for the separation of smaller globular light liquid pollutants to reduce the light liquid content in the outlet to 5mg/litre or less.
INLET DIP PIPE–FLAME TRAP. This provides minimum turbulence and prevents fire and inflammable vapours passing through to the drainage system.
TWO CHAMBER A non-turbulent flow, through two horizontal treatment chamber utilises the underflow principle to retain light liquids in all flow conditions.
- Containment chamber: Where Total Suspended Solids (TSS) silt, sediments, sludge and gross pollutants are trapped and settle on the chamber floor and where light liquids are contained.
- Coalescer chamber: Where light liquids separation is enhanced reducing it to 5mg/litre or less prior to discharge.
GRAVITY OPERATED Will function in the event of power failure and fits into existing pipe drainage systems or new sites.
MAINTENANCE. Easy and safe, with no entering of the tank required.
