Abstract
Disclosed is a system for treating wastewater. The system includes a microorganism clad structure positioned in a body of wastewater such that the microorganism clad structure is at least partially submerged in the body of wastewater. The apparatus also includes an aeration device, such as a propeller-type, surface mounted aeration device, supplying a horizontal flow of oxygenated water to the microorganisms attached to the microorganism clad structure such that the microorganisms may carry out a biological process.
Claims15
A wastewater treatment system comprising:
- a reduction zone at least partially defined by a first baffle,
- said reduction zone comprising:
- an influent pathway;
- plurality of floating microorganism clad structures;
- at least one reduction zone aeration device adapted to create a continuous flow of wastewater within the first reduction zone;
- and
- a first exit opening;
- a nitrification/denitrification zone at least partially defined by a second baffle,
- said nitrification/denitrification zone being adapted to receive wastewater from the reduction zone through the first exit opening and comprising:
- a plurality of nitrification/denitrification zone aeration devices;
- a plurality of nitrification/denitrification zone microorganism clad structures;
- and
- a second exit opening;
- and
- a discharge zone adapted to receive wastewater from the nitrification/denitrification zone through the second exit opening,
- said discharge zone including an effluent exit pathway,
- wherein the reduction zone is adapted to reduce biological oxygen demand and total suspended solids associated with the wastewater,
- further wherein the nitrification/denitrification zone is adapted to carry out at least one of biological oxidation of ammonia and biological reduction of nitrates.
