The oxidation ditch (OD) is a sort of equipment used for a long-term aeration. It consists of a long channel of an elliptical or circular shape equipped with an aeration equipment called a rotor for generating a water flow and stirring water in the channel to supply oxygen. Thought it requires a relatively large area, it has a simple structure and can be easily operated as well as being able to remove nitrogen easily. Thus, it has recently been widely used in relatively small wastewater treating plants.
#Advantages and Disadvantages
Advantages of the oxidation ditch are as follows.
1) It can be easily maintained.
2) It is hard to be effected by load fluctuations and forms only a little sludge.
3) OD can be easily controlled by changing the rotation of the rotor and the dipping depth.
4) It requires relatively little energy as the rotor is operated efficiency.
5) It can perform nitrification and denitrification easily.
Disadvantages of the oxidation ditch are as follows.
1) As the tank is large and the depth is small, it requires a large area.
It can be said the OD method is particularly suitable for a small scale equipment.
Oxidation pond is one of the biological systems which are used for the treatment of wastewater. It is considered as the secondary treatment method by which natural purification and stabilization of wastewaters like domestic sewage, trade waste and industrial effluents is accelerated. The biological treatment process in oxidation pond mainly involves an interaction between bacteria, algae and other organisms.
Oxidation pond typically operate in an extended aeration mode with long detention and solids retention time [5] and is a widely adopted technique for the treatment of domestic and trade wastes. It is one of the methods used extensively in the tropical areas of the world for treating the wastewater
This method would also have disadvantages that it requires extensive land area, potential odour problem, mosquito menace, little control over the effectiveness of the treatment process and the main disadvantage is seepage of effluents into soil which may also lead to ground water pollution.
Oxidation Ditch is preferred over oxidation pond !
