Water & wastewater: Turbidity testing uses technology triumph

摘要

The new Qdos 30 pumps from Watson-Marlow help to eliminate air locks and provide more accurate readings in bellow pumps. At the Pontstici 11 Water Treatment Works in the Brecon Beacons National Park, the Qdos 30 metering pump is taking elutriant from a DAF (dissolved air flotation) filtration plant and lifting it approximately three metres before it passes through a turbidity meter and returns by gravity back into the flow.
