SPEL Hydrosystem

SPEL Hydrosystem is a specialist stormwater filter, designed for installation within load bearing shafts and chambers of concrete or plastic construction. The pre fitted plastic housing is safe and easy to fit on site.

The SPEL Hydrosystem uses an up-flow process. This means there is a minimal head drop between the inlet and the outlet. The stormwater is treated within the unit by the following processes: sedimentation, filtration, adsorption and precipitation. It is suitable for Heavy Metal, TSS and Nutrient reduction.

The SPEL Hydrosystem is a German-engineered Stormwater Quality Improvement Device and is employed for heavily polluted traffic areas and has been granted general technical approval (Z-84.2-4) by the German Institute for Structural Engineering (DIBt).

Because of its up-flow process it can efficiently work in flat sites requiring only 250 mm fall across the device.

Multiple units can be manifolded together to treat higher flows. Each SPEL Hydrosystem will provide 12 L/s of treatment flow rate, installed in offline configuration.

The SPEL Hydrosystem has been tested in lab and in field under various conditions.

Hydrosystem Process

The initial treatment steps take place in the Dynamic Separator, where sedimentation of solid particles occurs within a radial flow regime, characterised by secondary flows.

A settling funnel to the silt trap chamber entrance ensures sediments are not remobilised. Above the separator are the filter inserts, covering the entire diameter of the unit’s housing, where the second treatment step takes place.

Water flows upwards through the removable filter element. As a result of both the upward flow within the filter element and the fact that the filter remains saturated, the rate of filter clogging by solids is both very limited and slow.

The filter inserts are easy to exchange.
