The slot injector aeration system was introduced to the USA market in 2003. It is a proven oxygen transfer technology with over 25 years of successful operating service in Europe. The entry to the market place has focused on the food, chemical and pharmaceutical industries. Like the conventional jet aerator, slot injectors are two-phase liquid/gas contactors but they have very unique geometrical characteristics that result in an oxygen transfer system with distinct advantages compared to conventional jet aeration systems:
Capital Savings: Up to a 60% reduction in recirculated liquid flow results in smaller and/or fewer pumps as well as significant reductions in the quantity and size of the liquid piping systems.
Capital Savings: Up to a 15% reduction in air flow results in smaller blowers and/or motors.
Energy Savings: The higher pressure pumping system allows for more efficient impellers.
Energy Savings: Increased velocity of the jet plume allows for raising the jet nozzles and canting them downward resulting in lower pressure blowers.
Energy Savings: The Injector design characteristics and performance database allows for optimizing the aeration system performance by varying both the liquid and air flow. Two phase flow control means maintaining the highest level of energy efficiency over a wide band of operating conditions.
In introducing the slot injector system, KLA Systems' goal was to focus on both capital and energy savings as well as broaden our application base. The biological treatment processes we have been involved in include: Conventional and High Rate AS processes, SBR, CLR, MBR and MBBR. Since 2004 there are 22 systems in operation.
