The ability to avoid moving water and wastewater by tanker also has significant environmental benefits in terms of reduced fuel consumption and environmental damage. RO mOdeling sOftwaRe upgRaded by nanOH2O Reverse-osmosis (RO) membrane manufacturer NanoH2O Inc has released version 2.0 of its Q+ Projection modeling software. Available for download on NanoH2O's website, the software offers new modeling options such as multi-pass designs, chemical dosing to adjust the feed stream pH levels, brine stream recirculation and partial permeate splits. Also included is the ability to model brackish-water RO elements based on data sheet specifications. Q+ version 2.0 is both PC and Mac® compatible. "Q+ is an innovative tool to illustrate the value of our QuantumFlux membranes," said Nicholas Dyner, Vice President of Sales and Marketing for NanoH2O. "Since we first launched the software, we have received very positive feedback on its usability and functionality. In addition to our commitment to lowering the cost of desalination through innovative membrane technology, we are equally dedicated to providing our customers with leading-edge tools and support." micROwave uv launcHed by seveRn tRent Pennsylvania-based Severn Trent Services has launched the MicroDynamics® Series OCS721, a new microwave-powered, open channel, ultraviolet (UV) system for municipal wastewater disinfection and water reuse applications. The product offers greater operating cost savings; lower whole-life cost; and long lamp life in a smaller footprint. Modules can be placed side by side in channels for design flexibility and to reduce civil works requirements. The system has been validated by National Water Research Institute for water reuse. The MicroDynamics OCS721 system meets dose, log reduction and water quality requirements for a variety of | 38 | Desalination & Water Reuse | February-March 2013 applications. The technology uses microwaves to energize low-pressure, high-output, electrodeless lamps to generate a UVC output of 254 nm, an optimal wave length for bacterial disinfection. The lamps also include a three-year warranty. The system features MicroPace™ a flow pacing technology that can match UV dose. "This unique feature allows for reliable and accurate control of operating conditions in real time to save energy," said Stan Shmia, UV product manager at Severn Trent Services. "MicroDynamics OCS721 represents a significant advancement in UV lamp technology. Costly lamp maintenance and replacement are now things of the past." Microwave-powered UV lamps do not have electrodes and remove the major failure mechanism found in traditional UV lamp technology. Severn Trent Services offers systems in openchannel designs for the UV disinfection of wastewater or closed vessel designs as an ideal solution for both wastewater and drinking water treatment. Xylem pilOting Reuse pROducts in flORida and califORnia Xylem is shipping two containerised MiPRO Advanced Oxidation Process (AOP) systems to Florida and California for pilot water-reuse projects. The Florida system, being delivered in mid-December 2013, will be piloted at the Hollywood Waste & Water Treatment Plant, while the California package was to be delivered to the Los Angeles County Sanitation District and Upper San Gabriel Valley Water District in mid-January 2013. Both containers contain an identical selection of Xylem Wedeco products including: ozone, ultraviolet (UV) and Promix. Promix is WEDECO's new AOP introduction system that permits effective treatment of unwanted contaminants, while completely controlling bromate formation. Each unit includes: fully automatic control system; parallel or series operation of UV and ozone AOP; peroxide, ozone and UV dose-control; online dissolved-ozone analysis; data trending; upstream and downstream online UVT analysis; and Ethernet connectivity. Recent Florida legislation requires that outfall discharges to meet higher requirements by 2018, and that, by 2025, 60% of treated wastewater must be reclaimed. The California pilot is a Water Reuse Research Foundation study sponsored by local utilities in Southern California to find a more economical treatment process than the current gold standard for indirect potable reuse. Xylems' Leopold brand will also be providing a biofiltration pilot, creating an opportunity to demonstrate an integrated solution across Xylem Water Solutions brands and technologies. l Xylem Inc announced on 16 January 2013 at the International Water Summit in Abu Dhabi that it will open a new office in Saudi Arabia in the coming months, as well as up to three additional offices in other key regional markets later this year. The company also launched its award-winning wastewater pumping solution, Flygt Experior, for customers in the Middle East, while making its debut in that market is Xylem's new open channel ultraviolet (UV) disinfection system, called WEDECO Duron.
