The Ecosol Net Tech will treat 100% of all flows in both free-draining and submerged environments until the net becomes full and disengages from the main unit, effectively eliminating the potential for flooding. Independent testing has found that the unit has little, or no, impact on the hydraulic performance of the drainage network.
The table below provide an indicative guide of the products treatable flow rate relevant to pipe sizes and gradient. With an empty filtration net the resistance is negligible and therefore the treatable flow rate is higher. However when the filtration net is full of pollutants and impervious the Treatable flow rate of the unit approaches zero at which point the unique release mechanism will disengage the next thereby enabling full pipe flows to continue without any hydraulic impact.
Treatable flow rate for the Ecosol Net Tech as a function of pipe diameter for a circular outlet conduits.
By-pass Capacity and Headloss
Headloss is defined as the hydraulic energy loss (embodied by the pressure reduction) experienced by the flow through the unit as a function of the flow rate through the unit. Testing by the Urban Water Resources Centre (The University of South Australia) confirmed that the release mechanism is constantly triggered before any significant build-up of pressure behind the filtration net.
In all cases the maximum head recorded was only 54mm above pipe obvert.
In summary independent testing has found that the Ecosol Net Tech has little or no impact on the hydraulic performance of the drainage network. Unlike other in-line or end-of-line systems, the unit’s unique release mechanism ensures there is no obstruction to flows in critical storm events, effectively eliminating the risk of flooding.
