Retrievable aeration system for wastewater treatment

A method for treating wastewater in a wastewater treatment tank, the method comprising the steps of:

• installing a track;
• coupling a plurality of pipe modules to the track such that the plurality of pipe modules are translatable along the track, each pipe module of the plurality of pipe modules defining a respective partially curved mating surface, a respective partially curved mating cavity, and a respective gas passage passing therethrough;
• and
• attaching a plurality of diffusers to the plurality of pipe modules;
• wherein the respective partially curved mating surface of a first pipe module of the plurality of pipe modules is inserted into the respective partially curved mating cavity of a second pipe module of the plurality of pipe modules;
• wherein the respective partially curved mating surface of the second pipe module of the plurality of pipe modules is inserted into the respective partially curved mating cavity of a third pipe module of the plurality of pipe modules;
• wherein each gas passage of the plurality of pipe modules is in gaseous communication with the other gas passages of the plurality of pipe modules;
• wherein each diffuser of the plurality of diffusers is in gaseous communication with the gas passages of the plurality of pipe modules.

A wastewater treatment system comprising:

• a wastewater treatment tank;
• a track, a portion of the track occupying the wastewater treatment tank;
• a plurality of pipe modules being coupled to the track such that the plurality of pipe modules are translatable along the track, each pipe module of the plurality of pipe modules defining a respective partially curved mating surface, a respective partially curved mating cavity, and a respective gas passage passing therethrough;
• and
• a plurality of diffusers attached to the plurality of pipe modules;
• wherein the respective partially curved mating surface of a first pipe module of the plurality of pipe modules is inserted into the respective partially curved mating cavity of a second pipe module of the plurality of pipe modules;
• wherein the respective partially curved mating surface of the second pipe module of the plurality of pipe modules is inserted into the respective partially curved mating cavity of a third pipe module of the plurality of pipe modules;
• wherein each gas passage of the plurality of pipe modules is in gaseous communication with the other gas passages of the plurality of pipe modules;
• wherein each diffuser of the plurality of diffusers is in gaseous communication with the gas passages of the plurality of pipe modules.
