KTM
Applications
Waste water treatment plants for food, beverage, dairy, seafood, poultry processing, laundries, bakeries etc.Dringking water treatment and disalination plants
Municipal waste water plant and power station
Automotive and chemical plants
Petroleum or oil & gas plants
Paper mill or textile industries
Features
Three functions in one pump- Simultaneously draws in air and water,dissolves air with its turbine impeller, and pumps pressurized water to flotation tank or other process
Highly efficient air-water dissolution
- Precision turbine pump technology and unique design make possible extremely high levels of efficiency in dissolving air into water
Simplified DAF operation with stable pump performance
- The multifunctional KTM eliminates the need for ancillary equipments and simplifies DAF operation
Compact in size and small footprint
- Easily retrofit or upgrade existing DAF systems
Minimal power consumption and save maintenance cost
- Highly efficient process with small pump and motor, no compressor power required, while the simple and robust structure of the KTM minimizes maintenance cost
