KTM Micro Bubble Generator

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
Equipment savings	No air compressor (saves energy, reduces noise, no compressor oil contamination into DAF flow). No large dissolving tank No static diffuser
Operational cost savings	Smaller pump compared to conventional systems, up to 67% lower energy consumption
Skilled staff savings	One time system setup and simple control No level control End-users can allocate skilled staff resources to other activities
Maintenance savings	Longer pump life Fewer parts and very simple to maintain
Reliability	Excellent track record KTM end-user clients include many internationally reknown brands.
Design flexibility	Very large range of sizes and materials to fit perfectly with end-user requirements.
Innovative	The system is much smaller, simpler, yet much higher performing compared to conventional systems.
