SPEL Puraceptor is a full retention 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. Treatable flow rates range from 2LPS to 200LPS. Pipe sizes range from 100mm to 450mm (larger sizes on request).
