Transcript of Tampa Bay Desalination Plant

Tampa Bay Desalination plant Period 7 Cleo Bianca Kaleigh Vocabulary 1.Reverse Osmosis-a technique for purifying water, in which pressure is
applied to force liquid through a semipermeable membrane
in the opposite direction to that in normal osmosis

2.Diatomaceous Earth Filter-A filter designed to use diatomaceous earth (D.E.)
as the filter medium. The D.E. is added through the skimmer with the pump on,
which deposits the D.E. on a grid. The D.E. becomes the filter medium.

3.hydrobiological monitoring program- includes water
quality and biological monitoring elements (benthic invertebrates,
seagrass, and fish).

4.Desalination- removal of salt

5.Cartridge filters- filters in place to protect reverse osmosis membranes

6.Sand filters- where smaller solids are filtered from the water

7.Traveling screens- filter out shell,wood,and other debris greater then 1/4 inches What Is the Tampa Bay Desalination Plant? The Tampa Bay Seawater Desalination facility is a drought-proof, alternative water supply that provides up to 25 million gallons per day of drinking water to the region. How the Tampa Bay Desalination Plant works A Diagram of the Desalination Plant http://www.tampabaywater.org/tampa-bay-seawater-desalination-plant.aspx Work Cited uses a process called reverse osmosis to produce drinking water from seawater. located next to Tampa Electric’s Big Bend Power Station, which already withdraws and discharges up to 1.4 billion gallons a day of seawater from Tampa Bay, using it as cooling water for the power plant. The Tampa Bay Seawater Desalination plant “catches” up to 44 million gallons per day (mgd) of that warm seawater, separates it into drinking water and concentrated seawater and dilutes the twice-as-salty seawater before returning it to the bay. Tampa Bay Desalination Plant History October 1996 - West Coast Regional Water Supply Authority issued a request for Proposal for a commercial developer to design, build, operate, and own a Desalination plant. (West Coast Regional Water Supply Authority later became Tampa Bay Water.)

1998 - Tampa Bay Water was created after a two- year governance process that culminated in contracts and legislation that changed the name, structure and operations of the West Coast Regional Water Supply Authority.

2000 - The Tampa Bay project has been plagued with problems

March 2003 - The Tampa Bay plant began the first tests of drinking water production.

February 2005- Many of the water pumps developed rust and corrosion problems because of cost cutting that led to the use of inappropriatematerials. Tampa Bay Desalination Plant History Cont.. Tampa Bay Desalination Plant Sources Groundwater Supply January 2008 - Tampa Bay Seawater Desalination Plant began producing high-quality drinking water

February 2010 - Tampa Bay Seawater Desalination Facility, the largest seawater desalination plant in the U.S., has passed the final two performance milestone tests. The tests required the plant to produce 25 million gallons of water per day (MGD) for 120 consecutive days and also average 20 MGD for 12 consecutive months. Both milestones were successfully completed. At 25 MGD, the plant provides about 10 percent of the Tampa Bay region's drinking water supply. As a result of passing the test, Tampa Bay Water will receive $31.25 million dollars from the Southwest Florida Water Management District, commonly known as SWFWMD.

January 2011 - Tampa Bay Water's $160-million desalination plant began making fresh water for the first time since April 19, 2010.

January 2013 - Today, the region is served by a combination of groundwater, river water and desalinated seawater, which has reduced wellfield pumping by more than 50 percent since 1998. Comes from the Floridan Aquifer Tampa Bay Water is permitted to withdraw an annual average of 120 million gallons per day (mgd) from 13 wellfields in Hillsborough, Pasco and Pinellas counties. http://www.tampabaywater.org/water-supply-source-groundwater.aspx Tampa Bay Desalination Plant Sources Surface Water/River Water Tampa Bay Desalination Plant Sources Tampa Bay Desalination Plant Tampa Bay Desalination Plant Sources Seawater Desalination First alternative to groundwater to be added to the Tampa Bay region’s wholesale water supply. When available, water is skimmed from the Tampa Bypass Canal, Hillsborough and Alafia rivers. http://www.tampabaywater.org/water-supply-source-river-surface-water.aspx Current Source Distribution Tampa Bay Desalination Plant is the only utility in the United States that takes advantage of a distinct blend of three sources to deliver affordable, high-quality drinking water to the 2.3 million businesses and residents it serves. Seawater coming into the plant goes through a rigorous pretreatment process then freshwater is separated from the seawater using reverse osmosis. The end product is high-quality drinking water that supplies up to 10 percent of the region’s needs. http://www.tampabaywater.org/tampa-bay-seawater-desalination-plant.aspx Located in Tampa Bay, Florida http://www.flickr.com/photos/ksandridge/2364526524/ http://www.hatchmott.com/projects/tampa-bay-seawater-desalination-facility What the Plant looks like http://www.tampabaywater.org/current-water-sources-in-use-tampa-bay-region.aspx "Agency."

A bill That would require the Department of Water Resources to
convene a Water Desalination task force to make recommendations
related to potential opportunities for the use of seawater and
brackish water desalination.

The Urban Water Management Planning Act- requires urban water suppliers to prepare and adopt urban water management plans for submission to the Department of Water Resources.
This bill would require a plan to describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply Who's Affected? http://www.fishingalberta.net/Cartoon%20Characters%20159.gif http://newsinhealth.nih.gov/2008/October/feature2.htm
