ACO QuadraCeptor

Four-stage rainwater and surface water treatment unit and runoff filtration system. Removes sediment and harmful pollutants from water. Supplied in a plastic housing single unit.

Benefits:

• Efficient and reliable system for the treatment of surface water run-off from roofs, car parks and roads – even in heavily trafficked areas – before discharge into the ground or to a surface water feature.

• Designed to remove heavy particles, silt, nutrients, and dissolved materials (such as heavy metals) from surface water as part of an integrated sustainable drainage solution, ensuring pollutants are not infiltrated into soil.

• Affordable, long-term and sustainable.

• Upflow filtration process results in minimal head loss between the inlet and outlet.

• Four stages are used to filter water: sedimentation, filtration, adsorption and precipitation.

• Filter elements can be cleaned and exchanged easily, with minimal maintenance required.

• Standalone unit which is easy to install.

The initial treatment steps take place in the hydrodynamic separator stage, where sedimentation of solid particles occurs. To prevent remobilization, settled material passes through a funnel trap into the silt chamber at the base of the unit. Secondary treatment of raw water occurs via a suite of filters located above the separator unit. These filtration units cover the entire diameter of the unit’s housing. As water flows upwards through the removable filter elements, the filtration media is kept saturated. Such saturation maximizes filter efficiency by minimizing the rate at which filter units clog.

Cover and frame are manufactured in accordance with BS EN 124.
