Krofta Engineering Limited–India’s No 1 Leading Technology DAF

Leading manufacturer and supplier of water treatment plants India Pressure Filter is a closed cylindrical vessel either vertical or horizontal (mostly vertical) containing the filter media over a collector system. Water flows from top downwards percolating through the media and is drawn off through the collector system at the bottom. Cycle of operation include back washing with or without air scouring, short rinse to waste and return to operation. The filter will effectively give clarified water having suspended solids to less then 20 ppm. The filter will have to be washed with Clarified water periodically. Advantages

Krofta Engineering We all know the old saying about how oil and water don’t mix. In the waste water treatment industry, however, it’s not so easy to divide these two dissimilar substances. In fact, removing oil from wastewater during processing requires the use of specific equipment. So, what is the problem with oil? Krofta Engineering Pasteurization or homogenization is the process used in the dairy industry for producing milk, butter, cheese or yogurt. Anaerobic treatment is most widely used for treating dairy wastewaters. The waste water produced has high level of BOD and COD load. This load has to be eradicated with the Dissolved Air flotation equipment before discharge for further treatment of water because it reduces effectively organic loading.

Advanced DAF system Technique 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 1200 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. Salient features / benefits of Krofta DAF clarifiers are:

Tannery and sludge Industry Tannery industry requires efficient DAF sludge handling system for its animal fat waste products. DAF technology is widely used in animal/food processing/meat/slaughtering applications to eliminate SS (suspended solids), fats, grease and oils from various samples of wastewaters. The elevated rates of processing, lesser footprints and suppleness in procedure has been always appreciated and has taken advantage of these applications. The DAF technology utilizes air to generate micro bubbles which helps in attaching the solids to float onto the surface to be thrown away. Dissolved Air Flotation is principally for solid to liquid or liquid to liquid separation.

Our Major Clients are Pulp & paper industry We work with organizations of all sizes and shapes across all industries, with most of our clients being large global organizations. Our customers are our customers because they value the service we provide, appreciate our global mind-sets, and respect our adherence to the created search model. The candidates we hold meet and often exceed expectations. They experience great career growth and work with our client companies for a very long time. Desalination of sea water Desalination embroil eliminating dissolved minerals from sea water and saline water (a mix of fresh water and marine water) and is gradually vital spring of fresh water. Krofta Engineering Ltd designs pre-treatment sea water desalination units for effective and competent desalination. DAF seawater pre-treatments a gravity focused solids liquid separation procedure. DAF is a developing procedure for the clarification of seawater prior to desalination by reverse osmosis. The success of DAF relies on the measure of bubbles and particles moving through water, and to the dissolution and precipitation of air.

Minicell-Dissolved Air Flotation Clarifier The clarifier has a special drive unit which is fitted to the shaft or cage. This cage or shaft can be provided with an overload sensor, if required by the client. By means of the shaft or cage, scraper arms with scraper blades are connected to the drive unit. Main Advantages:- Very Competitive price simple operation Excellent Performance with "difficult" and "fragile" sludge quality. Three different tank heightts avilable(choice according to the application) The tank and the construction of the minicell can be adapted to the application and to the the effluent.
