Aqua-Jet<sup>®</sup> SS-PW Aerator for Drink Water Applications

Aqua-Jet® SS-PW Aerator for Drink Water Applications

Aqua-Jet® aerators are installed in a wide variety of wastewater treatment schemes including activated sludge systems such as SBRs, MSBRs and extended aeration, as well as aerobic digesters, sludge holding, and equalization basins. It is also UL approved for TTHM stripping in potable water applications.

Municipal Water Treatment

Municipal Water Treatment

Otterbine aeration systems provide many benefits, but most importantly they improve water quality leaving clean, healthy ponds and lakes.
Automatic pH Balancing Systems

Automatic pH Balancing Systems

ClearBlu builds package pH balancing systems for high strength wastewater that are robust and low maintenance.  High strength strength wastewater can easily blind pH sensors, even when they are insertion mounted in a pipe.  ClearBlu utilizes digital self-cleaning immersion sensors for reliability, longer periods between calibration and lower chemical usage.

Jet Aeration

Jet Aeration

The Mass Transfer Systems bi-directional jet aerators are designed with jet aeration nozzles installed on both sides of the liquid / air jet aeration manifold. This configuration is most applicable for square or rectanglular tanks, larger lagoons, and sequence batch reactors where directional flow patterns are not desired

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
