Claims
- 1. A method of upgrading a lagoon containing wastewater to be treated, said method comprising the steps of:
partitioning the lagoon into a complete mix zone and at least one other zone in which the wastewater is not completely mixed; installing at least one floating air supply lateral in said complete mix zone; suspending a plurality of aerators from said supply lateral with the aerators in communication with the lateral to receive air therefrom for aeration and complete mixing of the complete mix zone; and suspending from said lateral at least one bioconcentration module having an open bottom and a concentration chamber for concentrating solids and allowing solids to settle and fall through the bottom of said module, whereby the settled solids can be circulated in the complete mix zone to maintain biomass equilibrium therein.
- 2. A system for treating wastewater in a lagoon, comprising:
a wastewater entry for admitting influent wastewater into the lagoon; a partition separating the lagoon into a complete mix zone and at least one other zone in which the wastewater is not completely mixed; a bioconcentration module in said complete mix zone providing a bioconcentration chamber therein for concentrating solids in the wastewater, said bioconcentration chamber having an open bottom and an inlet for admitting wastewater from which solids settle and drop through said open bottom; and a plurality of aerators in said complete mix zone operable to aerate the wastewater therein and to effect complete mixing of the wastewater and circulate solids in a manner to achieve biomass equilibrium in said complete mix zone.
- 3. A system as set forth in claim 2, including:
at least one floating air supply lateral in said complete mix zone for receiving air; and means for suspending said aerators from said lateral with said aerators communicating with said lateral to receive air therefrom.
- 4. A system as set forth in claim 3, wherein said bioconcentration module is suspended from said lateral.
