Verification Testing

Verification Testing

The SiltPrison has undergone testing and review at Alden Laboratories and by the Massachusetts BMP Clearinghouse, MASTEP. The SiltPrison’s treatment mechanism of filtration and settling were evaluated and tested at Alden for three different performance characteristics: re-entrainment, hydraulic characteristics, and sediment removal efficiency. Among the findings were very high flow rates,  a 62.6% sediment removal rating using newer 1-1000 PSD testing, and impressive performance of the SiltPrison to prevent re-entrainment and washout.
