Generic Node: Point 1

4.14 Generic nodes

The MUSIC User Manual describes the parameters that
can be defined for the generic node.

The structure of the generic node is similar to the GPT
node. If the pollutant reduction function is used, users
should express caution in adopting reliable pollutant
reduction efficiency rates. Similarly, assessment
authorities should not accept models which use the
pollutant reduction function unless the applicant has
demonstrated that:

 

the proposed treatment measure operates in a manner
which cannot be represented using one of the other
MUSIC treatment nodes

the proposed reduction efficiencies are justified by
rigorous scientific testing and results are published in
an credible engineering/scientific journal

the modelled pollutant reduction efficiency reflects
the published figures.

With reference to the first point highlighted, as the primary function of the Jellyfish is fine
sediment and nutrient removal, it cannot be modelled by any other MUSIC node available. The
closest node may be the GPT Node, however, while the Jellyfish filter is capable of removing
gross pollutants, its primary function is nutrient removal, and is often paired with a GPT
upstream of the Jellyfish, hence improving the longevity of the Jellyfish Filter. This
demonstrates compliance with point 1 of the Generic Node.
