Aqua BioMax®

Dual Treatment System

The Aqua BioMax dual treatment system is a unique combination of rotating biological contactor (RBC) technology and cloth media filtration. The package unit utilizes multiple RBC disks that are vertically mounted and closely spaced on a steel shaft, providing a large surface area for bio film growth. The disks rotate out of the wastewater to provide aeration for efficient BOD removal and nitrification. A cloth media drum filter follows the RBC to collect and remove the biological solids prior to the effluent discharge. This cloth media filter eliminates the need for a secondary clarifier. The Aqua BioMax system is an ideal solution for low flow applications (up to 100,000 gpd) where economical treatment and simple operation are critical.


Aqua BioMax® Operation


Biological Treatment

• Effluent from an upstream primary sedimentation basin enters the unit through the biological 
  treatment section

• Biofilm grows on the RBC disks, removing BOD and oxidizing ammonia

• RBC disks are 40% submerged and rotate continuously to allow for aeration of the biomass when
  exposed outside the tank water

• The oxygen method eliminates the need for mechanical aerators or diffusers systems with blowers,
  resulting in significant power savings


Filtration Treatment

• Flow then enters the filter portion of the unit and biological solids are collected on the outside of the
  cloth media and removed when during backwash cleaning

• Effluent is discharged and backwash water is returned to the upstream primary sedimentation basin

• Biosolids are typically anaerobically digested in the bottom of the pre-treatment tank and are
  removed every three to six months


Additonal Components

Rotation of the RBC disks and cloth media filter drum is accomplished by a small gear motor, 1.0 to
  2.0 horsepower (HP) (0.75 to 1.5 kilowatts kW)

• One to two 0.8 HP (0.6 kW) backwash pumps for the drum filter, depending on the unit size
