                    Overview of Ingal Music Nodes


Introduction
This Overview briefly describes how the Ingal Music nodes have been developed. The
majority of the results have come from flow proportional upstream down stream
sampling over numerous locations. Influent Event Mean Concentrations (EMC) and
Effluent Event Mean Concentrations have been imputed into the generic treatment node
transform functions. Supporting this paper is a series of documents detailing the exact
experimental procedure used in each study.

StormFilter in MUSIC set the high flow by-pass at the number of Cartridges x 0.95 l/sec.

Suspended Solids
The transfer function for suspended solids for the StormFilter node has been imputed
from the results of the “The Portland Submittal”. This paper details the results from 5
separate StormFilters. Figure 1 shows the influent / effluent relationship developed in the
paper.

Also attached as supporting information is the paper; “Total Suspended Solids (TSS)
Removal Using Different Particle Size Distributions with the Stormwater Management
StormFilter”. The particle size distribution in Stormwater is highly variable and greatly
affects the performance of the treatment device. This paper details Laboratory testing of
the StormFilter with different particle size distributions of synthetic sediment.

Total Phosphorous

The transfer function for total phosphorus has been developed from sampling 9 different
StormFilters over 55 storms. The results are detailed and discussed in the paper “The
Stormwater Management StormFilter Performance for Removal of Total Phosphorus”.
The Influent / Effluent relationship was developed through liner regression of the 55
storms as shown in figure 2 below.
