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
