Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
An industrial wastewater treatment plant may include one or more of the following rather than the conventional treatment sequence of sewage treatment plants: An API oil-water separator, for removing separate phase oil from wastewater. [43]: 180 A clarifier, for removing solids from wastewater. [44]: 41–15
Three wastewater/sewage clarifiers at the ʻAikahi wastewater treatment plant in Hawaii. They appear to have a floating cover [dubious – discuss] to reduce the odor because the plant is very close to a residential area. Circular clarifier with surface skimmer visible in the lower right.
Combined sewer outflow into the Anacostia River in Washington, D.C. Ratcliff Beach CSO discharges into the River Thames in London [7]. These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.

In the aftermath of the First World War the new treatment method spread rapidly, especially to the US, Denmark, Germany and Canada. By the late 1930s, the activated sludge treatment became a well-known biological wastewater treatment process in those countries where sewer systems and sewage treatment plants were common. [106]
Warrior Run became operational on February 10, 2000.

Originally from Zhangde Prefecture (彰德府; present-day Anyang, Henan), he serves as the garrison commandant of Dongchang Prefecture (東昌府; present-day Liaocheng, Shandong ...
Overwatering through irrigation by sprinkler may produce runoff reaching receiving waters during low flow conditions. [10] Runoff carries accumulated pollutants to streams with unusually low dilution ratios causing higher pollutant concentrations than would be found during regional precipitation events.
