Micronising Turbine Pump for DAF



Vikas Regenerative Turbine Pump or  Micronising Pump maximize dissolution rates of gas into liquids and easily mix difficult liquid / liquid solutions making it an ideal pump for a variety of mixing applications.

Pumps generate micro bubbles / nano bubbles with an average diameter of 5 µm, much smaller and more densely packed than conventional systems. This allows a higher amount of air to be dissolved into the water flow using smaller pumps. Power consumption has been recorded as low as 1/3rd  of the power consumption of conventional pumps: a dramatic reduction in running cost and CO2 output.

Dissolved Air Flotation (or D.A.F.) is a process in which tiny air molecules bind themselves to Solids particles and then float to the surface of a holding tank, allowing the Solids to be skimmed from the surface.

Micronising Pumps Or Regenerative Turbine Pump

Through the combination an innovative impeller design, the VIKAS  D.A.F. pump is able to create a sub-atmospheric pressure region in the seal chamber, forming compressed micro-bubbles that are then dissolved into the pumpage. This process helps eliminate the need for an air saturation tank and compressor required in many flotation systems. Vikas 's innovations enhance performance in many existing D.A.F. systems, as well as set up efficiency savings in new designs.

POWER CONSUMPTION REDUCED TO 1/3rd OF ORIGINAL

WITHOUT COMPROMISING PERFORMANCE

 

ELIMINATE EQUIPMENT

Immediately save on capital cost and plant space by eliminating the need for:

Air compressors

Large dissolving tanks

Frustrating tank level control

In-line static mixers

Ejectors

And replace large centrifugal pumps with the smaller Vikas  microbubble pump

Vikas DAF systems require only 1/5th of the space of most conventional DAF systems. The VIKAS MOCRONISING  pumps suction in air at atmospheric pressure and do not require static mixing devices or long holding periods under pressure like conventional systems.

Vikas Micronising dissolved air flotation (DAF) pump is a very effective way to separate suspended solids and emulsified oils from industrial waste streams. Microscopic air bubbles are produced during normal operation and mixed with waste water containing the suspended contaminates. The small bubbles attach themselves to the suspended particles, which gives them a net positive buoyancy. These buoyant clusters of particles and bubbles rise smoothly to the surface forming a float which is removed by skimming.

 

Air and recycled "clean" effluent is introduced to the pump suction. The proportion of air/water is controlled by the operator through simple valves. Under pump discharge pressure this air effluent mixture becomes supersaturated with air micro bubbles. This enriched stream is then recycled back into the dirty effluent and fed to the DAF unit. Up to 35% air can be achieved with 100% saturation and micro bubble size smaller than 30 micron.

 

In conventional DAF systems, air saturated water is brought into the flotation tank by by means of compressors, pressure tanks and a tension release valve. Due to the cost and nature of the components, typical DAF systems are a large investment that require more maintenance and service and cost more to operate. Vikas DAF system is nearly twice as efficient with lower operation costs.

DAF has become successful due to the excellent purification effect, the low consumption of chemicals and the low maintenance and investment costs. With the Vikas DAF system, Dissolved Air Flotation is taken to new levels of efficiency and performance.

DAF Design Features and Benefits

For DAF applications, Vikas Daf pumps or Micronising Pump or Regenerative Turbine Pumps meet the following requirements:

Long service life   because of low wear caused by the inevitable contamination of liquids with solid particles. Please remember, proper selection of materials of construction is critical.

Steady pumping characteristics even with changing points of operation.

Sufficient blending of effluent and air to obtain maximum entrainment of air micro bubbles @ 30 micron size.

Standard pumps are not able to meet these requirements. The hydraulic parts of Vikas Micronising pumps have been specially designed to cope with problems which arise when pumping effluent/air mixtures. The distinctive feature of the Vikas DAF  pump is the impeller, open on both sides, and the innovative hydraulic design of the impeller blades.

Vikas Micronising  DAF System Construction Materials

The following materials are available for construction of the Vikas DAF Pumps for the following pH levels for the wastewater stream that you will be pumping:

pH value less than 3 ......................Stainless Steel

pH value 3 to 5.9 ...........................Bronze

pH value 6 to 10 ............................Gray Cast Iron

pH value 11 to 14 ..........................Gray Cast Iron (all iron)
