Nikuni KTM (Karyu Turbo Mixer)

Nikuni KTM Microbubble generator for DAF and liquid-gas dissolving applications :-

Introduction 
The KTM pump performs three functions simultaneously Suction, Mixing, and Pressurization ideal for DAF and liquid-gas applications. KTM Micro/Nano Bubble Generator typically generate Micro/Nano bubbles with an average diameter of below 10 um(micron). Its reliable performance results in a highly stable overall system.
 
Features for DAF Applications :-
 - High rate of suspended solids removal 
 - Supplying a highly dense microbubble output
 - Highly consisten 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 For Gas-Liquid Mixing

  • Blends and dissolves thoroughly a variety of gases such as oxygen, nitrogen, ozone, carbon dioxide, hydrogen and chlorine into fresh water, sea water and chemical fluids.
  • Performs continuous and efficient mixing and dissolving for difficult to dissolve "liquid and liquid" and "gas and liquid."
  • Compact, lightweight and space saving for mixing applications
  • Easy to maintain and operate
