The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.
In 2016 Hillsborough County Public Utilities, a forward thinking organization, initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100 percent of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges. The pilot project validated direct potable reuse, which is now a key initiative for many central Florida utilities due to the implementation of the Central Florida Water Initiative requiring the additional utilization of reuse water resources.
The Honouliuli Water Recycling Facility (WRF) includes filtration and UV disinfection to treat to Class R-1 reuse standards for various uses, including irrigation. In order to maintain high-level reuse, simplify maintenance, and reduce operation costs, the Honolulu Board of Water Supply decided to replace its 15-year-old TrojanUV4000™ with a TrojanUVSigna™. With the high cost of power in Hawaii, this system upgrade will provide significant power savings (estimated at 75%) and will enable equipment payback in less than 2.5 years.
Hollywood, Florida’s 55.5 MGD Southern Regional Wastewater Treatment Plant (SRWWTP) treats wastewater from Hollywood and six neighboring municipalities in the southern region of Broward County. Florida’s outfall rule requires the city to begin a process to largely eliminate the use of its ocean outfall and implement 20.4 MGD of additional reuse on an annual basis.
Water professionals are seeking innovative approaches to address water supply challenges associated with population growth, drought, and environmental protection.
As a part of a massive expansion plan for Chhatrapati Shivaji International Airport located in Mumbai, India, a wastewater recycle project was contracted in 2011 to cater to the growing requirements of the expanded airport.
The Georgia Aquarium system operates as a closed loop and is able to recapture and reuse over 99% of the water in its exhibits. In order to reuse the majority of the tank water, the aquarium must ensure that waste from its aquatic residents is removed.
Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation.
Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.
The installation of a new water treatment system at the Plum Creek Water Purification facility in Castle Rock, Colo. is enabling the town to treat and deliver renewable surface water to residents and businesses.
The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site. The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.
A new report from the Oklahoma Water Resources Board’s Produced Water Working Group indicates that oil and gas companies looking for ways to dispose of large volumes of wastewater should focus on recycling those liquids within the oil and gas fields, and not use it for irrigation or other surface applications where human and environmental exposure is a risk.
California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.
“Water Champion” Paula Kehoe looks to do for the nation what she did for San Francisco — to greatly expand water reuse opportunities and implementation. In this Q&A, she discusses her new role as chair of a national commission for onsite non-potable reuse, the San Francisco model, and the best practices and obstacles for sustainable water operations.
Arizona is taking steps to allow for direct potable reuse throughout the drought-plagued state. With the practice legalized for wide use, its popularity around the world may rise.
The Water Environment & Reuse Foundation introduces a “bundle of research” to help direct potable reuse and its practitioners reach full potential.
