The ozone supply units feed into a manifold that contains a plurality of fluid paths and has one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of each ozone supply unit. The manifold includes a plurality of flow switches configured to transmit control signals to one or more controllers of each ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply units to generate ozone. The manifold also includes a plurality of fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply units into the water flowing through the fluid paths. ## Claims ### Claim 1 A system for creating an oxidation reduction potential (ORP) in water to control biofilm buildup in a wastewater treatment system, comprising: a plurality of ozone supply unit enclosures, each ozone supply unit enclosure including: one or more ozone output ports formed through a sidewall of each ozone supply unit enclosure; a plurality of ozone generators disposed within each ozone supply unit enclosure, the plurality of ozone generators being fluidically coupled to the one or more ozone output ports; and one or more controllers disposed within the ozone supply unit enclosure, the one or more controllers being communicatively coupled to the plurality of ozone generators;
