Nikuni KTM Micro Bubble Pumps at a glance

NIKUNI, a Japanese company which has produced high quality equipment for various water related industries has developed a unique compact micro-bubble generator for use in dissolved air flotation systems, called the KTM.

The KTM has a highly precise and sophisticated pumping mechanism that can generate massive quantities of micro-bubbles by means of three hydro-dynamic principles:

  • Negative pressure sucking both air and water simultaneously from each port
  • Air is effectively transferred to the water
  • Pressurized, air-enriched water is discharged

The pressurized, air-enriched water is transferred into the bottom of the dissolved air flotation tank from where it makes a bubble sparkling formation, spreading and rising up to the water surface pulling fine material, oils, fats, fibres and more with it to form a sludge mat. This mat is then skimmed.


Features for DAF Applications

  • High rate of suspended solids removal
  • Supplying a highly dense Microbubble output
  • Highly consistent dissolved air flotation
  • Fine adjustments not necessary when operation or start up
  • Easily retrofit to pre-existing systems
  • Small installation footprint
  • Minimum power consumption
  • Low power required for KTM (no compressor required)
  • Easy maintenance and minimum operational cost
  • Compact and simple pump structure
  • Quiet operation
  • No compressor, level controls, saturation tank required
Features of Dissolved Air Floatation with NIKUNI KTM
