Side Stream Treatment for Overflow

A method for treating wastewater, comprising:

• introducing wastewater from a source of wastewater to an influent conduit;
• measuring a property of the wastewater in the influent conduit to provide a property measurement;
• introducing at least a portion of the wastewater to a biological reactor based at least in part on the property measurement;
• introducing at least a portion of the wastewater to a fixed film biological reactor;
• introducing an additional portion of the wastewater to the fixed film biological reactor based at least in part on the property measurement to provide a fixed film effluent;
• introducing at least a portion of the wastewater to a ballast reactor tank based at least in part on the property measurement, the ballast reactor tank configured to provide a ballasted effluent;
• and
• introducing the fixed film effluent to the ballast reactor tank.

A method of facilitating the treatment of wastewater in a wastewater treatment system comprising a conduit connected to an outlet of a source of wastewater and an inlet to a biological reactor, the method comprising:

• providing a diverter fluidly connectable to the source of wastewater and upstream of the biological reactor of the wastewater treatment system, the diverter configured to direct a portion of the wastewater from the conduit;
• providing a fixed film biological reactor having an inlet connectable to the diverter, the fixed film biological reactor configured to receive an overflow volume of the source of wastewater and to provide a fixed film effluent;
• providing a bypass line fluidly connectable to the diverter and configured to bypass the fixed film reactor;
• and
• providing a ballasted system fluidly connectable to the fixed film effluent, the ballasted system comprising:
• a ballast reactor tank configured to provide a ballasted effluent;
• and
• a source of ballast material fluidly connected to an inlet of the ballast reactor tank.

A method of treating wastewater during a high flow period, comprising:

• establishing a first liquid circuit having liquid to be treated flowing therein from a source of wastewater to an inlet of a first biological reactor;
• establishing a second liquid circuit having liquid to be treated flowing therein from a source of wastewater to an inlet of at least one of a second biological reactor and a separation system;
• and
• establishing a third liquid circuit having an effluent from the second biological reactor flowing therein from the second biological reactor to at least one of the first biological reactor and the separation system.
