How Whitewater Series Units Work:

Oxygen is pumped into the system allowing the bacteria thrive and grow in much greater numbers than would occur naturally. This “overpopulation” of bacteria speeds the process of breaking down the sewage, making it safe for release into the environment, and is defined as the aerobic treatment process.

This process occurs entirely within the self-contained Whitewater Aerobic Treatment Unit which is comprised of an outer mixing tank and a cone-shaped settling chamber. Raw unsettled wastewater enters directly into the mixing tank where mixing occurs through an open air distribution system.

The mixed liquid then enters the settling chamber from the bottom. The settling chamber maintains a quiet condition which allows solids to settle down and re-enter the mixing chamber for more processing. The liquid is hydraulically displaced upward and is discharged as clear, odorless treated effluent which meets or exceeds permit requirement.


  • Industry proven solution with NSF/ANSI 40 certification
  • Robust design accounts for minor settling in difficult soils
  • Flexible and easy installations in OEM or 3rd party tanks
  • With no mechanical parts internal to the unit, the Whitewater is easy to maintain
  • Low life cycle costs resulting from energy efficient design
