Water. desalination + reuse

BUSINESS Two Saudi SWRO contracts go to NanoH2O Desalination membrane manufacturer NanoH2O Inc has won supply contracts for two large seawater desalination projects in Saudi Arabia. The first project, for phase II of the Jubail desalination plant, was awarded by Al Fatah Water & Power International. NanoH2O's QuantumFlux reverse-osmosis membranes will produce 13,000 m3/d of desalinated water. The second project, a desalination plant to be designed by AES Arabia at the King Abdullah University of Science & Technology Research Park, will produce 15,000 m3/d of water. Both installations are scheduled for 2014. IDE buys Flowserve pumps for Carlsbad IDE Technologies has purchased three large vertical seawater intake pumps from Flowserve Corporation for the Carlsbad seawater reverse osmosis (SWRO) desalination plant in Carlsbad, California. This order was booked in the third quarter of 2013. The Flowserve pumps are constructed in super duplex stainless steel to supply the highly corrosive raw seawater to the plant. Additionally, eight large vertical doublesuction twin-volute pumps constructed in 316L stainless steel were specified and purchased to transfer the potable water from the SWRO plant into the San Diego County Water Authority distribution system. IDE was selected to design and subsequently operate the 189,250 m3/d Carlsbad plant. With an expected completion date during the fourth quarter of 2015, this plant is projected to be the largest desalination plant in North America. Desalitech to supply reuse system to steel mill Desalitech is to supply an advanced wastewater recovery system to Mid American Steel and Wire, a leading supplier in the US wire and rod industry. The Desalitech system, which will recycle up to 60,000 GPD (227 m3/d) of wastewater for reuse in the rod mill at the Madill, Oklahoma, facility. This system will reduce both the disposal costs and environmental impact of the operations at the mill. The integrated treatment solution will include pretreatment steps for removing coNTracT BrIEfS ____ For more details, visit www.desalination.biz __ contaminants and debris followed by reverse osmosis purification and is capable of achieving high recovery from the challenging wastewater created by steel manufacturing. Historically, wastewater has been hauled away for disposal at a significant cost. The Desalitech system will treat the wastewater inside the facility with the highest possible efficiency to maximize the yield of valuable recycled water, ensure its purity, reduce plant discharges and associated costs, and minimize environmental impact. LIqTEch gETS chINa foLLow-Up LiqTech International Inc of Denmark has received an additional purchase order for its silicon carbide membranes from RIPE (Huzhou), a Chinese membrane system integrator. The order is the third placed by RIPE in 2013: significant order sizes of 256 m2, 256 m2 and the latest 480 m2 of membrane product.

Ovivo says this will be the largest MBR installation in the USA. The final design includes an MBR installation utilizing space in the existing aeration tanks. All solids separation will be accomplished in the existing aeration tanks; therefore a final clarifier and tertiary filter expansion to increase peak hydraulic capacity is unnecessary. Biological nutrient removal will be accomplished by reconfiguring the existing aeration tanks into industryproven treatment zones within the existing aeration tanks. Engineering studies have shown that the MBR system will also alleviate the need for the WRF's existing disinfection system, providing financial incentives and eliminating safety concerns with this type of chemical treatment. Although the peak hydraulic capacity is being designed for 88 MGD, Douglas Harris, Canton facilities engineer, says the facility can pump up to 108 MGD (409,000 m3/d) through the plant. Conversion of the existing primary and secondary clarifiers to equalization tanks will allow Canton to store peak flows over 88 MGD. Harris told D&WR that the construction contract is anticipated to begin in Feb 2014 with commissioning of the first MBR train in early 2015. Completion of the entire project is scheduled to occur by 2017. a generic operator training simulator system for the Saline Water Conversion Corporation in Saudi Arabia. MBr doUBLES qUEENSLaNd pLaNT A sewage treatment plant in Queensland, Australia, will double its capacity to 1,000 m3/d with the help of membrane bioreactor technologies provided by GE. The company will provide the technology to Monadelphous, the Australian engineering, construction, maintenance and industrial services company that will upgrade the plant.
