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.
"When domestic wastewater is treated, a solid by-product accumulates in the wastewater treatment plant and must be removed periodically to keep the plant operating properly. The collected material, called biosolids or more commonly "sewage sludge," is high in organic content, and contains moderate amounts of nutrients that are needed by plants.
Much of the water reclaimed from the Everglades was sent to newly developed areas. [80] With metropolitan growth came urban problems associated with rapid expansion: traffic jams; school overcrowding; crime; overloaded sewage treatment plants; and, for the first time in south Florida's urban history, water shortages in times of drought.

The Florida panhandle (also known as West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida. It is a salient roughly 200 miles (320 km) long, bordered by Alabama on the north and the west, Georgia on the north, and the Gulf of Mexico to the south.
Other types of wastewater treatment plants include agricultural wastewater treatment and leachate treatment plants. Treating wastewater efficiently is challenging, but improved technology allows for enhanced removal of specific materials, increased re-use of water, and energy production from waste.

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
Wastewater treatment plants play a major role, Ruyle said. They receive PFAS-contaminated water from homes and industry and about 50% of drinking water plants in the US are downstream from one of ...
The term "first flush effect" refers to rapid changes in water quality (pollutant concentration or load) that occur after early season rains. Soil and vegetation particles wash into streams; sediments and other accumulated organic particles on the river bed are re-suspended, and dissolved substances from soil and shallow groundwater can be flushed into streams.
