The KLa Difference – Technology, Experience, Knowledge and Service

KLa Systems is a company dedicated to making the world's waterways cleaner. We are an equipment supplier specializing in custom engineered mixing and aeration technologies for biological wastewater treatment processes. Our innovative jet aeration, jet mixing and Slot Injector ™ systems for industry, water utilities, and municipalities can be found in effluent treatment plants around the world.

KLa Systems does not design the biological treatment process but we offer the oxygen transfer and mixing technology that makes the biological process better. We do this by working closely with industrial clients, water utilities, consulting engineers, design-build teams, and turnkey contractors to insure their conventional or advanced bioprocesses have an oxygen transfer system that is economical, reliable, and energy efficient.

 Slot Injector Aeration System for Membrane Bioreactor (MBR) plants:

Slot Injector ™ Systems: The Slot Injector™ aerator is similar to a modern jet aerator but uses a unique geometrical nozzle configuration to achieve higher efficiencies. This feature results in a device that can dissolve large quantities of gas with significantly less motive liquid pumping. Like a conventional jet aerator, the hydrodynamic conditions within the Slot Injector aerator and the high energy discharge plume produce continuous surface renewal at the gas/liquid interface resulting in higher alpha factors than conventional air diffusers. 

MBR applications: The applications for our Slot Injector™ System include conventional EQ Tanks, AS processes, oxidation ditches, aerated lagoons, SBR, as well as any bioprocess where fine screening is a standard pretreatment step. For advanced processes we have applied the technology to MBBR, MBR, various multistage nutrient removal processes, and industrial fermentation. We are particularly enthusiastic with the progress we have made in the MBR sector as over the past several years we have successfully completed 30 MBR projects using our Slot Injector™ aeration technology. These plants are for industry and although mainly Food & Beverage plants, we have also supplied systems for leachate treatment, chemical, and petrochemical processing effluent.

Slot Injector™ aeration technology is ideal for MBR processes as it offers high oxygen transfer rates in the concentrated biomass environment of the membrane bioreactor. Other important features are; flexible operation using DO feed back to VFD controlled pumps and blowers for improved process control and optimum energy management, superior mixing at high MLSS concentrations, injectors and piping system are fabricated of highly corrosion resistant polypropylene, FRP and stainless steel, and the injectors can be cleaned out using our airlift back-flush system without the need to take the basin out of service. This key feature means the Slot Injector™ system will maintain long term, trouble-free operation.

A Slot Injector™ System from KLa Systems consists of the all in-tank components (injectors and piping system), back-flush system, recirculation pumps, air blowers, pump recirculation piping system, all required documentation, installation inspection, plant commissioning, and operator training.

For your next project please consider our Slot Injector™ System and take advantage of what sets KLa Systems apart from the competition: technology, experience, knowledge, and a total commitment to customer service.
