BUSINESS pall grabs another naval water-generator contract Membrane-based freshwater generators are to be supplied to the UK���s Royal Navy by Pall Corporation after successful sea trials. The Pall Integrated Membrane System (IMS) has been chosen for the Royal Navy���s Type 45 Destroyer, designed and built by BAE Systems and the most advanced warships ever produced in the UK. Sea trials of the IMS system have demonstrated that it works efficiently with the high contamination levels found in some coastal waters. The fully automatic, cleanable IMS helps reduce maintenance tasks and has a lower cost of ownership compared to conventional water treatment systems. The IMS freshwater generator integrates hollow-fiber microfiltration (MF) and reverse-osmosis (RO) modules. It removes suspended solids, eg, bacteria and viruses, dissolved components (such as salts), and other contaminants from seawater. The system significantly reduces the requirement to store spare filter cartridges and can be used to boost water production on a permanent or temporary basis. A few weeks earlier, the US Navy���s Office of Naval Research had contracted Pall Corporation for a multi-phase project to develop an advanced shipboard desalination system specifically for operations in coastal waters. Pall will create a detailed design for navy ship water treatment using MF and RO that will increase the volume and reliability of fresh water generation while reducing energy and maintenance requirements. Whether participating in active maneuvers or returning to shore, military vessels require highly-reliable water treatment systems to meet the demand for fresh water. In addition to being energy and resource intensive, traditional seawater desalination technologies are often unreliable. Coastal sea water can be especially difficult to treat due to extremely high concentrations of suspended solids, as well as biological and organic contaminants. The navy also limits chemical usage on ships, creating restrictions to approaches used in land-based desalination plants. During the first six-month phase of the project, Pall scientists will adapt the latest membrane technologies to design a solution capable of producing 4,000 GPD (15,140 L/d) of potable water. In the year-long second phase of the program, a prototype system will be developed and tested on land. In the final 18-month phase, a fully compliant system will be tested for six months on a naval ship. KAUST SWRO plant won by AES Arabia A US$ 14 million contract for a 15,000 m3/d seawater reverse-osmosis (SWRO) desalination plant for the King Abdullah University of Science & Technology (KAUST) Research Park in Saudi Arabia has been awarded to AES Arabia Ltd. The contractor for the research park is China National Chemical Engineering Company under the management of Saudi Aramco. AES Arabia, a Riyadh-based water and wastewater management company, has long experience with Saudi Aramco work. The seawater will be sourced from a deep-water open intake and will be extensively pretreated before it is pumped into the desalination plant. The desalted water will be further treated for the removal of boron and subsequently remineralized to meet WHO standards. Although built for a research institution, the plant design and manufacturing will be according to the stringent standards followed in all Saudi Aramco oil and gas projects. AES Arabia has previously built an 8,000 m3/d membrane bioreactor sewage treatment plant and participated in the construction of the main 52,000 m3/d SWRO desalination plant for KAUST.

The business includes the company���s membrane and ion-exchange products for desalination and water treatment. Siemens Water Technologies also operates its own research center in Singapore, which includes a novel energy-efficient technique for electrochemical desalination of seawater. Siemens said on 8 November 2012 that it intended to focus its water business on automation and drive solutions for the control of water applications for municipalities and industry, and for seawater desalination plants. ���This business shows only minor synergies with our industrial portfolio, as the skills for water treatment are primarily based on chemical expertise.

NEw CEO aNd BUSINESS lINES fOr STw US water services provider STW Resource Holding Corp announced a new chief operating officer (COO) on 25 October and expanded business lines, including large-scale desalination and oil/ gas water reclamation. The new COO, Lee Maddox, has served as an account executive and risk manager for a number of oil and gas operators and service contractors for the past 15 years, earning the designation of Certified Risk Manager. Lee was promoted to vice president and received numerous awards for his leadership in sales and as a team leader with individual annual sales of US$ 10 million. He has been a partner and manager in several oil and gas service companies including Viper Products & Services and Black Wolf Enterprises.
