Notes for the table of Treatment Rates and Storage Capacities:

*1 Treatment Flow Rates have been calculated from the results of a 225mm diameter large scale laboratory model, with no tidal influences.

*2  Treatment Flow Rates have been calculated by extrapolation from the results of 225mm diameter large scale laboratory tests, with no tidal influences.

*3  Storage capacities for both floatables and solids allow for more than 12 months of typical urban pollutant generation rates for developed areas.

*4  Total floatables capacity includes free oil. Free oil only capacity is included in brackets.

*5  Sum of capacities of floatables storage, treatment, and solid storage zones.

The recommended 'K' value for an Q-Guard™ stormwater treatment device is 1.3, based on pipe full velocity head in the downstream pipe reach. This value is based on a stormwater treatment device operating within a stormwater system for pipe design flow.
