Saudi Arabia Interest gauged for 2 big SWRO IWPs Developers are invited to respond to a call for expressions of interest (EOIs) from Water and Electricity LLC (WEC) for two new independent water projects (IWP) on Saudi’s Red Sea Coast. The projects are the Shuqaiq 3 IWP, located 550km (345 mi) south of Jeddah and the Yanbu 4 IWP, located 350km (220 mi) north of Jeddah. The projects, which will both employ SWRO technology, have capacities of 380,000 m 3 /d (100.4 MGD) and 450,000 m 3 /d (119 MGD), respectively. In both cases, WEC is considering bundling the greenfield contracts with the acquisition, rehabilitation and operation of nearby plants currently owned and operated by the Saline Water Conversion Corporation (SWCC). For the Shuqaiq 3 IWP, it includes the Shuqaiq 1 plant, a combined power and MSF desal plant, which was commissioned in 1989 and has a desal production capacity of 97,000 m 3 /d and 108MW of power production. For the Yanbu 4 IWP, the existing assets include the 100,000 m 3 /d (26.4 MGD) MSF, 357MW Yanbu 1 plant commissioned 1981; the 144,000 m 3 /d (38 MGD) MSF, 163MWYanbu 2 plant commissioned in 1998; the 128,000 m 3 /d (33.8 MGD) Yanbu SWRO plant commissioned in 1998; and the 68,000 m 3 /d (18 MGD) MED Yanbu Expansion plant commissioned in 2013. WEC is being advised by a team that includes SMBC (financial), ILF Consulting (technical) and DLA Piper (legal). The EOI submission deadline is 23 November 2017, with the developer selection planned for finalization in mid-2019. EDS Desalination Pavilion Aquatech delegates are reminded to visit the European Desal Society’s (EDS) Desalination Pavilion at Hall 3, Booth 03.220, and also, to participate at Aquastage, Hall 3, Booth 03.118 on Thursday, from 14:00-17:00.

Company News Voltea launches point-of-use CapDI Voltea has come a long way since its CapDI capacitive deionization technology received the Technology Idol award at GWI’s 2010 Global Water Summit in Paris. Later the same year, it made its commercial debut at Singapore Water Week and announced a capital raise to support its rollout. The Netherlands-based company has continued to garner technology awards and raise capital almost as fast as it has been able to increase its industrial and commercial installation list. By 2016, the company’s growth had outpaced its ability to manufacture CapDI modules, so the company opened a new robotic assembly plant to increase production and improve product quality. At this week’s Aquatech, the company is introducing its newest product: DiUse © , a market-ready, point-of-use (PoU) device that is self-cleaning and delivers no-salt water softening and low-cost brackish water desalination. The internet-enabled DiUse can be remotely monitored and controlled, and can send performance reports that include conductivity and inter-module pressure data.
Perhaps DiUse’s most interesting feature is its ability to “set it and forget it”. According to Voltea CEO Bryan Brister, once the unit is tuned to meet a desired product water conductivity, it will continue to deliver the desired water quality, regardless of fluctuations in feedwater quality. And, it will automatically adjust the amount of electricity that it requires to meet the water quality goal.

“Traditional RO or thermal desal systems often remove far more salt than is required, whereas DiUse has the ability to tune the amount of TDS removed. Besides the obvious energy savings, this is important for some applications, such as producing optimal beverage quality,” explained Dr Voltea’s DiUse

Brister. “Coffee, for example, is best when brewed with water having a conductivity of about 100 μS/cm. With DiUse, you can dial in the water quality accordingly, to produce a superior, consistent beverage quality.” Because of these features, Voltea is targeting the hotel, restaurant, café (HoReCa) market, “although it may be well-suited as a salt-free, whole home softener for one- or two-member households,” Brister added. DiUse has undergone multi-unit, multi-site, multi-water type testing at multiple performance settings equaling years of real-life performance, including more than six months of use in the world’s largest retail coffee shop. It is designed for use on well water or municipal water supplies with a TDS of less than 3,000mg/L, and depending on feedwater TDS, can produce up to 5 L/min (1.3 gpm), with a salt removal of 25-95 percent and a water recovery of 40-95 percent. DiUse includes built-in flow, conductivity and voltage monitoring and is automatically self-cleaned with a dilute citric acid solution, typically on a quarterly or semi-annual basis. Voltea invites Aquatech attendees to visit them at booth 07.452 and sample some coffee and espresso beverages made by an award-winning, internationally recognized champion barista.
Company News ROSA retired, say “hello” to WAVE
Dow’s long-awaited WAVE (Water Application Value Engine) modeling software is making its debut at Aquatech this week. The software integrates three technologies— UF, RO and ion exchange—in one comprehensive tool that lets users model more efficiently and accurately and design multi-technology systems much faster. According to Fabien Creus, Dow’s WAVE program manager, the new interface is more user friendly, has improved and consistent algorithms and harmonized data for all products and processes. WAVE will replace ROSA (which was released to the public in 1993), UFlow, IXCalc and CADIX programs. Although it has not yet been possible for WDR to evaluate the entire package, some of its best new and expanded RO features are: • Improved internally staged design (ISD) capability, with each element in a pressure vessel now able to be uniquely defined
• Split permeate available with ISD • Design warnings by element position
• Bypass, pass & stage level concentrate recycle loops • Batch modeling with the possibility of simultaneous batch case creation

How many times have you been surprised to see the size of the puddle of water left behind on the pavement as you backed your car out of the driveway on a hot summer day? Ford Motor Company now reports that two of its engineers have come up with a simple system to capture the condensate in a reservoir, then route it through a 0.1 micron filter to remove contaminants and pump the water to a small faucet on the center console. Ford says that a car’s cold air conditioning lines can condense about two liters (68 oz) of water from the air per hour. According to WDR ’s calculations, if a typical auto were to consume 2 L/hr (0.5 gal/hr) of fuel while idling with the A/C running, it would take three weeks of continuous operation to produce 1 m 3 (264 gal) of water and would consume about 1000 L (14 gal) of fuel. Unlike an atmospheric water generator (AWG)—which essentially does the same thing—it is probable that the 2-A1707392 Omya_GWI_190x130.indd 1 Technology On-the-go-H 2 O
unit developed by Ford would only be called upon to produce water while the car was actually being used to go somewhere. In that case, and assuming the car was traveling at highway speeds for three weeks continuously, the car would consume 4,500 L (1,200 gal) of fuel and travel 48,000km (30,000 mi), while producing nearly the same 1 m 3 of water. There was no mention if this would be an option available on future Ford vehicles, nor was there any indication that an onboard wastewater treatment, water reuse or anti- Legionella system was being considered. 13.09.17 16:38

(32,000-380,500 gpd) of seawater. The company said that it shrinks footprint and reduces pump- related power consumption by making use of the vessel’s existing seawater cooling system pumps. When Woodard & Curran acquired California-based RMC Water and Environment late last year, it said that the two companies would operate under a co-branded identity through 2017 before transitioning to operating under a single name in 2018. With the approach of the one-year anniversary of the acquisition, the company said, “as the seasons change, we want to remind you that our name is changing too”; beginning at the start of the new year, the two firms will operate as Woodard & Curran. The Middle East Desalination Research Center (MEDRC) has announced that it will support 32 water research projects conducted by Palestinian researchers at Palestinian Universities. The topics have been approved by MEDRC and the Palestinian Water Authority after an analysis of current water sector needs. Female researchers will lead 50 percent of the projects, and a list of the projects and participating universities is available at http://tinyurl. com/ycfvewbs . Fluence has been awarded its first contract to upgrade a centralized wastewater treatment plant with its SUBRE membrane aerated bioreactor (MABR) technology.
