Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles.  The inner nozzle the traditional jet aerator is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s.  Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin.  For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear of the jet nozzles.  It was when we entered the thermophilic biosolids treatment market when we determined we needed to upgrade to Kynar PVDF.  This material is both extremely chemical and wear resistance over a wide range of temperatures.

The Slot Injector™ System is a superior jet aeration system that is specifically applied to industrial biological treatment processes where fine screening is a standard pretreatment operation in both conventional and advanced air activated sludge applications.

The high-alpha factor and clean water oxygen transfer performance of KLa’s jet aeration technology results in low energy costs and reduced off-gas volume for industrial and biosolids applications.

Jet Mixers offer superior mixing of large diameter tanks by providing uniform energy distribution while minimizing power input. This mixing technology results in decreased reaction times, improved liquid blending and off bottom suspension of light, organic solids.  Jet mixers are used in wastewater treatment applications where blending, solids suspension, flow generation, or chemical reactions are key process parameters.  Jet mixers are fabricated of either FRP or stainless steel with no moving parts in the tank. Conventional pumps are used for the jet motive flow and are located just outside the tank for optimizing energy efficiency and ease in maintenance.

KLa Systems floating effluent decanters are used to draw clarified liquid from near the liquid surface of sequencing batch reactors and aerobic digesters.

A typical system consists of the Slot Injector™ aerators, jet mixers or jet aerators complete with in-basin piping system, back-flush system, liquid recirculation pumps, and air blowers.  The pumps supplied are either end suction centrifugal, submersible, or self-priming. Low pressure air is delivered by positive displacement blowers, screw compressors, multi-stage or high speed centrifugal blowers.


KLa Systems Inc. is an equipment supplier specializing in custom designed mixing and aeration technologies for biological wastewater treatment processes. We are the market leader and our team of personnel has over 30 years’ experience in the water industry, having successfully completed well over 1,300 projects worldwide.
