Can Your DAF Pump Aerate A Shirt? This One Can… | Dissolved Air Flotation At Low Cost

On one of the early Keystec DAF Pump tests, a client was simply too cheap to install screens in his wastewater system. During a pilot test one of the workers accidentally dropped his shirt into the whitewater. Later the shirt was retrieved from the processed water- the Keystec Airwhip® pump unharmed. Multi-stage pumps used toContinue Reading

Dissolved Air Flotation for Solids? How to cope with the problem of white-water systems and pump blockage. A true DAF generates dissolved air.  The process involves dissolving atmospheric air to the greatest saturation possible under pressure and then releasing the dissolved air in the form of microscopic bubbles with the shock developed in a back-pressure valveContinue Reading
