2. Parshall flume - Wikipedia

   en.wikipedia.org/wiki/Parshall_flume

   Named after its creator, Dr. Ralph L. Parshall of the U.S. Soil Conservation Service, the Parshall flume is a fixed hydraulic structure used in measuring volumetric flow rate in surface water, industrial discharges, municipal sewer lines, and influent/effluent flows in wastewater treatment plants. The Parshall flume accelerates the flow by ...

3. Palmer-Bowlus Flume - Wikipedia

   en.wikipedia.org/wiki/Palmer-Bowlus_Flume

   The Palmer-Bowlus flume, is a class of flumes commonly used to measure the flow of wastewater in sewer pipes and conduits. The Palmer-Bowlus flume has a u-shaped cross-section and was designed to be inserted into, or in line with, pipes and u-channels found in sanitary sewer applications.

4. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...

5. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag ...

6. Cutthroat flume - Wikipedia

   en.wikipedia.org/wiki/Cutthroat_flume

   The Cutthroat flume is a class of flow measurement flume developed during 1966/1967 that is used to measure the flow of surface waters, sewage flows, and industrial discharges. Like other flumes , the Cutthroat flume is a fixed hydraulic structure .

7. Sewage treatment - Wikipedia

   en.wikipedia.org/wiki/Sewage_treatment

   The term sewage treatment plant (STP) (or sewage treatment works) is nowadays often replaced with the term wastewater treatment plant (WWTP). [7] [8] Strictly speaking, the latter is a broader term that can also refer to industrial wastewater treatment. The terms water recycling center or water reclamation plants are also in use as synonyms.
