The South Valley Water Reclamation Facility is located at 7495 South 1300 West in West Jordan, Utah. It serves the south end of Salt Lake County.
"The South Valley Water Reclamation Facility is located approximately 15 miles south of Salt Lake City on the West Bank of the Jordan River in West Jordan, Utah. This Facility provides wastewater treatment for the cities of Sandy, Herriman, Midvale, West Jordan, South Jordan, Riverton, Bluffdale, Draper, Copperton, and unincorporated portions of South Salt Lake County. This encompasses a 200-square mile service area. The South Valley Water Reclamation Facility Board consists of representatives from Midvale City, West Jordan City, Midvalley Improvement District, Sandy Suburban Improvement District, and South Valley Sewer District.
The facility is an oxidation ditch design and was put into service in 1985. The 1998 capacity was 38 million gallons per day, at a total construction cost of $40,000,000. In the year 2010 the capacity will be expanded to 50 million gallons per day.
The architectural design concept for the entire facility is based on softening the visual impact of a large industrial plant on a suburban area and creating compatibility with the character of the region." SOURCE
"The Administration services is the nerve center of the Facility where operations monitoring and coordination, lab facilities, operator training, and other administrative functions are provided. All public and private access to the Facility is approved at the Administration building. Using a state-of-the-art computerized SCADA (Supervisory Control and Data Acquisition) system, the operators interface with the plant and its various processes. They collect all information pertaining to flows, dissolved oxygen content, pump speed, etc., to assist in their process control decision making. Some equipment and processes are controlled from “keyboard entry” by the operator. All plant functions are monitored “live time” and changes are seen when they are actually taking place." SOURCE
What is the capacity of the facility?: Maximum capacity is at 50 million gallons per day
Describe the biological treatment technology used.:
Oxidation Ditches
The heart of the Facility is the oxidation ditch treatment process. In this process, wastewater is aerated for 16-18 hours, which allows microorganisms to grow and thrive by consuming much of the organic material in the wastewater. Solids are maintained in the system for 25 days. Ammonia is converted to nitrate to protect the life forms in the Jordan River from toxicity.
Aeration in the oxidation ditches is accomplished by turbine-type fixed aerators. Each 150 hoursepower aerator is capable of transferring more than 300 pounds of oxygen per hour into the wastewater. The aerators also provide all the mixing and propulsion forces required to keep the solids in suspension.
Final Clarifiers
Biological organisms and other settleable material from the oxidation ditch are removed from the wastewater in the final clarifiers. The clarified effluent is piped to the disinfection system. Underflow from the clarifiers, consisting of settled biological sludge, is returned to the oxidation ditch to maintain a stable microorganism population. Fixed weirs help assure an even flow of distribution and prevent short-circuiting.
RAS/WAS
The Return Activated Sludge/Waste Activated Sludge (RAS/WAS) pumping system provides the capability to return activated sludge from the final clarifier underflow to the oxidation ditches to maintain the micro-organism population. Also, activated sludge is wasted to the gravity thickener to control the micro-organism population and prevent excessive build up of solids in the oxidation ditch process.
Gravity Thickeners
Waste sludge from the final clarifier underflow or directly from the oxidation ditches is pumped to the gravity thickeners for thickening in advance of the dewatering operation. Waste sludge enters the thickeners at approximately 0.5 percent solids concentration and is thickened to 2.0 percent solids. The thickened sludge is then pumped to the Solids Processing Building for dewatering.
Potential odors at the gravity thickeners are controlled by enclosing them and passing the resulting air and off gases through a granular activated carbon (GAC) scrubber system. Hydrogen sulfide and other odorous organic compounds are absorbed onto the carbon and removed from the air stream before discharge in the atmosphere.
How are biosolids (sludge) managed?: Thickened biological Waste Activated Sludge (WAS) from the gravity thickeners is conditioned with high molecular weight organic polymers in the Solids Processing Building and dewatered using belt filter presses. Liquid sludge at 1.5 – 2 percent solids is
What technology is used for disinfection prior to dicharge of treated water?: The wastewater is injected with chlorine for disinfection. Following chlorination, the wastewater passes through the chlorine contact basin. Detention time in the basin is 30 to 60 minutes, which is sufficient to allow the chlorine to react with and contr
Who is the owner/operator fo the facility?: South Valley Water Reclamation
How is the facility governed?: The South Valley Water Reclamation Facility Board consists of representatives from Midvale City, West Jordan City, Midvalley Improvement District, Sandy Suburban Improvement District, and South Valley Sewer District.
