With both USA and overseas production capabilities K_La Systems can economically deliver a jet aeration system anywhere in the world and have successfully delivered systems to 20 different countries. Biological processes we have been involved in include: Conventional and High Rate AS processes, SBR, CLR, ASB and ATAD.

K_La jet aerators transfer oxygen by simultaneously introducing large amounts of high kinetic energy liquid and air through a series of jet nozzles. Intense mixing and high turbulence result in a fine dispersion of gas and liquid, which is then discharged from the jet nozzle, allowing the plume to mix with and entrain the surrounding liquid.

Jet aeration technology is unique because the highly turbulent, fine bubble cloud creates an enormous, constantly renewed gas/liquid interface inside the jet and along the horizontal plume, resulting in high mass transfer coefficients (K_La). When the horizontal momentum from the jet is transferred to the surrounding liquid, superior process mixing results.

A K_La jet aeration system consists of the individual jet aerators and in-basin piping system, and typically includes liquid recirculation pumps and air blowers. Other available jet system components include:

• Back-flush system
• Out-of-basin air and liquid piping system
• Air flow measurement devices and instrumentation
• Dissolved oxygen control system
• Acoustical enclosures

K_La’s jet aerators, manufactured in our own production facility, are constructed of fiberglass-reinforced plastic (FRP), which is an economical, lightweight, durable material that resists corrosion and is easily fieldassembled. Our FRP materials and manufacturing techniques meet all of the latest ASTM and NBS standards.

K_La Technology is applicable across a wide range of industries and climates. Typical applications include biological suspended growth processes, mesophilic and thermophilic aerobic biosolids treatment processes, and equalization/holding basins.

The key benefits of using a K_La jet aeration system include:

• Superior aeration efficiency
• High percentage of oxygen utilization
• Superior mixing and process control

These benefits, along with the physical features of the system improve the aeration system life cycle by:

• Reducing capital costs
• Lowering energy costs
• Lowering maintenance costs
• Reducing aerosols
• Reducing off-gas volumes
• Reducing plant footprint

• Complete Mix Activated Sludge
• Plug Flow Activated Sludge
• Oxidation Ditches (CLR)
• Sequencing Batch Reactors
• Pure Oxygen
• ASB
• ATAD
• Aerobic digestion
• Equalization
• Sludge Holding
