Back pressure is the term used for the hydraulic pressure required to create a flow through a chromatography column in high-performance liquid chromatography, the term deriving from the fact that it is generated by the resistance of the column, and exerts its influence backwards on the pump that must supply the flow.
The Back River Wastewater Treatment Plant is a wastewater treatment plant in Baltimore, Maryland, United States. It serves the city of Baltimore, which owns and operates the facility, as well as Baltimore County, Maryland , and discharges treated water into the Back River and the Patapsco River .
During the injection process, electrical energy can be generated by the head pressure of the water flowing back into the aquifer. This stored water is recovered during late summer and early autumn for irrigation needs. [citation needed] Both of these well types use a down-hole control valve. ASR can also be used to re-inject water used by HVAC ...
The O'Shaughnessy Dam is located on the Scioto River near Dublin, Ohio, United States. The dam forms O'Shaughnessy Reservoir, which is a major source of drinking water for the city of Columbus . It was completed in 1925 following recommendations of then superintendent Jerry O'Shaughnessy (for whom the dam was named).

McConnell.
In water treatment plants, backwashing can be an automated process that is run by local programmable logic controllers (PLCs). The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline or when the differential pressure across the filter exceeds a set value.
The largest wastewater treatment plants can be defined in several ways. The largest in term of capacity, both during dry and wet-weathers, is the Jean-R.-Marcotte Wastewater Treatment Plant in Montreal. With full secondary treatment of effluents it would be the Deer Island Waste Water Treatment Plant of Boston.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
