Introduction and how the AWT System works:


Depending on the chemical makeup of the wastewater in relation to the effluent requirements, a biological wastewater treatment system might be composed of several different processes and numerous types of microorganisms. They will also require specific operational procedures that will vary depending on the environment needed to keep biomass growth rates optimal for the specific microbial populations. For example, it often is required to monitor and adjust aeration to maintain a consistent dissolved oxygen level to keep the system’s bacteria multiplying at the appropriate rate to meet discharge requirements.

In addition to dissolved oxygen, biological systems often need to be balanced for flow, load, pH, temperature, and nutrients. Balancing a combination of system factors is where the biological treatment process can become very complex.

Fixed-bed bioreactors, consist of multiple-chambered tanks in which the chambers are packed tight with porous ceramic, porous foam, and/or plastic media; the wastewater passes through the immobilized bed of media. Of all biological treatment systems, FBBRs can hold the most contaminant-eating microbes in the smallest volume, which makes FBBRs space-saving and energy-efficient technologies ideal for treating waste-waters from medium to medium-high BOD feed levels down to very low effluent levels. The media is engineered to have a high enough surface area to encourage a robust bio-film formation with long solids lifespan, resulting in low sludge formation and lowest sludge disposal costs.


At Amatheia, well-engineered fixed-bed will allow wastewater to flow through the system without channeling or plugging. Chambers can be aerobic and still have anoxic zones to achieve aerobic carbonaceous removal and full anoxic denitrification at the same time. More advanced biological processes can be facilitated with these systems (for example, nitrification, denitrification, desalination, sulfide-reduction, and anammox), by having unique bacterial populations colonize the bio-film media in separate tank chambers, which can be uniquely configured to treat your facility’s specific wastewater constituents.
