SHOWCASE and life-cycle cost available today. It utilizes vertical-tube fallingfilm evaporator design, a proven technology for treating difficult produced water sources. Benefits of SmartMod over conventional evaporator systems include 10% lower power consumption. Its multiple-section design ensures ASME distillate quality, and on-line washing allows for continuous distillate production at >70% of design capacity during washing. SmartMod is also engineered to minimize field installation labor and costs. With its dramatically reduced center of mass and evaporator weight, the SmartMod module and vessels eliminate the need for building a large evaporator building or expensive foundation labor and materials. Its innovative design also reduces freight costs for transportation of the complete system to site. Smaller UF model releaSed by QUa at aWWa ShoW A smaller compact ultrafiltration (UF) membrane module was introduced by Pennsylvania-based QUA® at the ACE12 Annual Conference & Exposition in June in Dallas, Texas. The new Q-SEP 2008 hollow-fiber UF module offers greater flexibility when designing smaller filtration systems particularly for commercial customers as well as for other customers where water demand is low. Q-SEP 2008 is most suitable for customers such as offices, hospitals, hotels, whole house POE and so on. Q-SEP 2008, which is NSF-certified, is a self-encapsulated hollow-fiber ultrafiltration membrane module (inside-out) with a membrane surface area of 20.0 m2. The total length including end cap is 1,015 mm, and the unit has a diameter of 225 mm. The Q-SEP model 2008 module weighs 28 kg. As with other Q-SEP models, the 2008 module is mounted vertically. danFoSS completeS itS Small/mediUm ro pUmp range Danfoss has completed its range of pumps for the small and medium-sized reverse-osmosis (RO) high-pressure pumps with the introduction of the APP 11-13. With its capacity of 11-13 m3/h, the APP 11-13 is ideal for RO systems that produce 100-125 m3/d. If the APP 11-13 is installed with iSave, Danfoss' integrated isobaric energy-recovery device, it can even handle up to 250–300 m3/d. "A lot of customers have been waiting for us to complete development on these pumps," says Jesper Bentzen, sales director for the Danfoss RO Division. "Worldwide, we expect strong growth in the market for small and medium-sized RO plants – and our latest APP 11-13 pump – with a capacity that is ideal for many smaller commercial applications – is going to be right at the sweet spot for many projects." Like the rest of the APP pump portfolio, the new APP 11-13 packs a lot of power into a small and efficient package. No other high-pressure pump on the market is smaller or lighter, and with volumetric efficiency up to 97% and very few can claim to be as efficient with electricity. The axial piston design results in constant flow regardless of pressure variations, as well as fewer moving parts for improved reliability and reduced maintenance costs. Belt drivers and pulsation dampers are both things of the past with the APP series, and no oil lubrication is needed, as the pumped medium itself lubricates moving parts. SWro high-preSSUre pUmp SUpplieS Up to 30,000 m3/d Sulzer Pumps chose the recent European Desalination Society conference in Barcelona to launch a new high-pressure pump aimed at large seawater reverse-osmosis (SWRO) desalination plants. The MSD-RO pump, derived from Sulzer's MSD range is an axially split, multistage, double-volute pump for membrane feed in SWRO plants. Train capacities range from 20,000-30,000 m3/d. MSD-RO is the result of Sulzer's experience in supplying highpressure pumps for large SWRO plants worldwide totalling 2.5 millions m3/d installed capacity. The pump delivers a high level of hydraulic performance over its defined operating range, including exceptionally high efficiencies and optimum suction performance. Its top efficiency and robustness complies with the most stringent requirements of the desalination market. The MSD follows the release in December 2011 of the MBN-RO, Sulzer's latest ring-section multistage high-pressure pump for membrane feed in RO desalination plants. It has also been designed specifically for high-pressure membrane feed services in SWRO applications. In addition to its very good efficiency, it allows simple maintenance with quick and easy access to main wear parts, such as mechanical seals or bearings, without disassembling the suction and discharge nozzle. Manufactured in Duplex or Superduplex as standard materials for a variety of seawater qualities to avoid pitting and crevice corrosion, it covers capacities up to 1,000 m3/h.
