OXIDATION POND - Coggle Diagram
OXIDATION POND
DEFINITION:
- Popular sewage treatment method for small communities
-
- Used for simple secondary treatment of sewage effluents
-
- Also known as stabilization ponds or lagoons
- Require maintenance and periodic desludging in order to maintain this standard.
HOW OP WORK?
- The production of this oxygen replenishes the oxygen used by the hetertrophic bacteria.
- Typically oxidation ponds need to be less than 10 feet deep in order to support the algal growth.
- The production of these supports the growth of algae in the oxidation pond.
- The use of oxidation ponds is largely restricted to warmer climate regions
- Within an oxidation pond heterotrophic bacteris degrade organic matter in the sewage
MAINTENANCE OF OP
- The degradation is relatively slow and the effluents containing the oxidized products ned to be periodcally removed from the ponds.
- Oxidation ponds tand to be inefficient and require large holding capacities and long retention times.
- Oxidation ponds also tend to fill, due to the settling of the bacterial and algal cells formed during the decomposition of the sewage.
