Aqua BioMax®

Dual Treatment System

The Aqua BioMax dual treatment system uniquely combines cloth media filtration with rotating biological contactor (RBC) technology. The package unit utilises multiple vertically mounted and closely spaced RBC disks on a steel shaft. Thus, providing a larger surface area for bio film growth. BOD and nitrification removal is achieved through the disks rotating out of the wastewater for efficient aeration. The collection and removal of biological solids is achieved prior to effluent discharge, by using a cloth media drum filter, following the RBC. The use of the cloth media filter removes the requirement for a secondary clarifier. The Aqua BioMax system is an ideal solution for low flow applications (up to 380,000 L/day) where simple operation and economical treatment crucial.

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 oxygenation method removes the requirement for mechanical diffuser systems or aerators with
blowers, which results in a significant energy efficiency improvement.

Filtration Treatment

• Flow then enters the filter portion of the unit, where the biological solids are captured on the outside of the cloth media, prior to removal 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

Additional Components

• Rotation of the RBC disks and cloth media filter drum is accomplished by a small gear motor (0.75 to 1.5 kilowatts kW)
• One to two 0.6 kW backwash pumps for the drum filter, depending on the unit size
