Aluceptor - Full Retention Separators
Our Aluceptor range shown in the table opposite features retentions from 1800 litres up to 14,400 litres in single cell
units. Larger systems are available up to 250,000 litres.
The Nominal Size of the unit is given to the treated flow through the unit, which is calculated from the
given catchment area that the separator is serving.
The calculation which identifies the size of retention unit required is:
A (drainage area m2) x 0.018 = Nominal Size Unit.
So as an example the separator required for a catchment area of 333m2 would be calculated as follows:
A (333m2) x 0.018 = NS 5.9. So for this application we would supply our NS6.
However, as can be seen in the chart this would only give a Full Retention capacity of 3880 litres.
Typically if this were a petrol forecourt fuelling area, then the volume in the separator would not meet
the requirement for retention. It is recommended that the unit be sized to retain the spillage of the
largest tanker cell that is being delivered to a particular hard standing area.
