Other available Slot Injector and jet system components include the out-of-basin air and liquid piping system which includes stainless steel pipe, isolation valves, expansion bellows, supports and pressure gauges. Additional scope of supply is available upon request.
KLa Systems is in a unique position to assist industries in meeting the challenges of production expansion and/or optimizing energy usage in their wastewater treatment facility. By retrofitting our Slot Injector™ system with all types of existing diffuser systems within existing tanks/basins, higher (15-60%) oxygen rates can be achieved.
Water Environment Research Foundation (WERF) studies show that fine-pore diffusers have reduced oxygen transfer performance and increased pressure requirements over time due to clogging, and the biggest drop-off is in the first 24 months of operation.
It is not uncommon for these types of aeration systems to require frequent cleaning and replacement within the first five years of operation.
This is not the case with Slot Injector™ aerators or jet aerators, as they are available with an optional Back-Flush System that allows for cleaning out the injectors/jets without the need for basin drainage or to have an operator enter the basin.
Back-flushing these aeration systems is conducted essentially with an airlift pump, that reverses the flow through the inner injector/jet nozzle, resulting in a powerful air/liquid stream that clears trash and debris from the system. With much larger openings and self-cleaning capabilities, Slot Injector™aeration systems and jet aeration systems are known for long term reliable operation.
