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.
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
- Easy access to internal components
- Utilizes exclusive OptiFiber® cloth filtration media
- Reduced footprint requirements
- Pre-assembled, complete with integrated electric control panel allowing rapid installation and start-up
- Minimum energy consumption
