Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.
Pressure in Wastewater Treatment
Water reuse or water recycling or water reclamation takes water from a variety of sources, treats it, and reuses it for agriculture and irrigation, potable water supplies, groundwater replenishment, industrial processes and environmental restoration. Removing impurities from wastewater and sewage requires the removal of all types of physical, chemical, and biological contaminations in Sewage Treatment Plants (STP). While the water may be treated to obtain any level of quality desired, as its purity increases, so does the cost of obtaining that purity.
In the U.S., the Safe Drinking Water Act and the Clean Water Act provide regulations to protect the quality of drinking water source waters, community drinking water, and waterbodies such as rivers and lakes. Moving the water between various processing stations in a treatment plant requires numerous pumps. Since contaminants are removed at different steps, there are many locations that could limit or restrict the water flow. In the secondary treatment of wastewater, Waste Activated Sludge (WAS) and Return Activated Sludge (RAS) as well as scum are among the different flowing constituents. For successful long-term operation, pressure sensing could occur at several points in the reclamation process.
The water reclamation process in the city of St. Petersburg, Florida identifies 11 pumps to achieve their desired water quality.
