Krofta Engineering Limited

Krofta clarifiers have retention times as low as 3 minutes and with a possibility of resource recovery in some cases as opposed to the sedimentation methods characterised by very long retention times. Krofta, is the world leader in this field having more than 10,000 installations running successfully all over the world. The advanced DAF system offered by Krofta does not warrant a separate flocculation tank, flocculation mixer, flash tank and flash mixer. The Air Saturation Tank of yesteryears is replaced by the patented Krofta Air Dissolving Tube (ADT) which provides effluent saturated with air in residence time of 10 seconds. Air requirement is also very low as compared to the DAFs of earlier designs.
