In aerobic biological treatment, microorganisms use the waste’s organic component with oxygen, which produces cell growth and end products of carbon dioxide and water. The most popular is the activated sludge process, which is commonly used in wastewater applications. This process provides high quality effluent and is capable of significantly reducing B.O.D. The bacterial process oxidizes the soluble and suspended organics to carbon dioxide and water in the presence of oxygen. The organic material is converted into new cells or used to support growth of the existing cells. The excess of cells is solids.
To provide one of the most advanced aerobic biological treatment systems, the best elements of activated sludge (suspended growth) and trickling filter (attached growth/fixed film) are combined into one treatment system. However, the system predominantly functions as a fixed-film system where microorganisms attach themselves to the surface of the media and the spaces between the media granules also serve as areas for suspended biomass growth, resulting in a significant increase in total microorganism concentration. In addition, detention time decreases while solids retention time within the system increases.
ColOX™
The TETRA® ColOX™ system is an advanced aerobic biological treatment system which combines the best elements of activated sludge (suspended growth) processes and trickling filter (attached growth/fixed-film) systems with innovative design features to achieve superior performance. Configured as a Submerged Packed Bed Reactor, the ColOX system utilizes both fixed-film and suspended growth biomass, offering greater efficiency, operational reliability and versatility than any other aerobic biological treatment process.
Key Benefits:
- Nitrify ammonia nitrogen
- Achieve superior BOD removal
- Remove suspended solids
- Oxidize complex organics with a reduction in equipment and space requirements
