The “KROFTA” SUPRACELL has a distinct edge Over other systems when the sludge or water is recycled to the process and where the type of waste water varies. For Pulp and Paper Industry the small volume and short retention time are extremely important, where the supracell is used as a save-all and in the de-inking process.
The degree of fractionation and/ or microstraining depends on many factors; inlet consistency, spray pressure, inlet filler content, micron opening size, and particularly fines content of the fiber fraction. The following results can be expected l Coarse impurities are separated out. All the water is microstrained.
Krofta India was started in 1983 as a joint venture collaboration with Dr Milos Krofta. He was the founder of Krofta globally and developer of the Dissolved Air Flotation Technology. We offer proven designs by incorporating DAF (Dissolved Air Flotation Technology) to handle waste water treatment systems for industrial as well as municipal applications.
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 3500 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.
