Aqua Jet®

Surface Aerator

The Aqua-Jet® surface mechanical aerator may possibly be the most imitated waste water aerator in the world. But, as with other manufactured products, copies never equal the original in terms of reliability and durability.


Vibration Controlled Design

The continuous heavy-duty operating life of rotating equipment, such as a wastewater aerator, demands a vibration-limiting design that will assure smooth operation long after the unit has been installed. The velocity must be controlled to 0.3in/sec. or less. If this limitation is not met, early machine failure is inevitable.


Proper design and the use of the highest quality materials have made the Aqua-Jet aerator the most durable and reliable wastewater aerator in the industry. On properly maintained units, Aqua-Jet aerators outlast other aerators 2 to 1. On poorly maintained aerators, Aqua-Jet aerators outlast other aerators by more than a 3 to 1 margin. Scheduled maintenance consists only of motor bearing lubrication 2-4 times per year, depending on motor size.


The Aqua-Jet has been approved for TTHM removal. Learn more >

Featured Story

MacLaren's Pulp Mill Upgraded to Meet New Requirements and Aid in Protecting the Environment

MacLaren Industries’ kraft pulp mill, located in Thurso, Quebec was built in 1958 and used only a primary treatment process for treatment of its pulp waste until the mid 1990s. It was at this time that more stringent effl uent requirements for BOD5 were defined for discharge into the nearby Ottawa River. To meet the new requirements and to make a commitment to protecting the environment, MacLaren decided to employ a secondary treatment process. Read More
