IDA World Congress:
Desalination market grows to meet global water needs T
he International Desalination Association World Congress has been held recently in Perth, Australia. The gathering provided the opportunity for the industry to assess the current market for desalination and review some recent advances in technology.
The global desalination market continues to grow led by demand for seawater desalination, according to the 24th GWI/IDA Worldwide Desalting Plant Inventor, which covers 12 months ending June 30, 2011. The numbers were released today at a briefing on the State of Desalination held at the IDA World Congress on Desalination and Water Reuse. The total global capacity of all plants currently online is 66.5 million cubic meters per day (m3/d), an increase of 8.8 percent over the 2010 inventory. The total worldwide capacity of all desalination plants, including
those online, under construction and/or contracted, stands at 77.4 million m3/d. In all, including plants under construction, 747 plants with a combined capacity of 5.3 million m3/d have been added to this year’s inventory, as compared with 499 plants and 3.1 million m3/d added to the previous inventory. Of the capacity added to this year’s inventory, a total of 2.3 million m3/d has been contracted since January 1, 2011. There are now 15,988 desalination plants worldwide, up from 15,180 in 2010.
The International Desalination Association World Congress has been held recently in Perth, Australia.
Desalination is used in 150 countries around the world, providing some or all the daily water needs of an estimated 300 million people. “The desalination market continues to grow despite completion of major projects in key markets and the effects of global economic issues. Population and economic growth, pollution of existing water resources, and climate change continue to drive the need for new and reliable sources of water. Desalination is one of the answers. It continues to be an increasingly important part of global water solutions for the

21st century,” said Lisa Henthorne, Director and Past President of IDA. The IDA World Congress heard that seawater desalination leads the response to addressing the world’s water challenges, comprising nearly 60 percent of the total worldwide installed capacity. Saudi Arabia is the largest desalination market, followed by the UAE, Spain and the United States. Australia, site of the 2011 IDA World Congress, ranks seventh. Geographic markets expected to experience future growth include China, India, Latin America and South Africa, with a large potential for desalination technologies in the industrial sector, oil and gas, and mining.
Desalination technology There was a wide selection of new technology for desalination and water reuse markets on show at the IDA World Congress. Here we highlight a few examples.
IDE Technologies IDE Technologies has launched IDE PROGREENTM, an environmentally-friendly Reverse Osmosis (RO) system for water desalination. IDE says that PROGREEN reduces operational costs and increases return on investment by optimising the energy consumption, eliminating the use and handling of chemicals, and offering a customisable, self-maintained platform. This results in affordable, sustainable, high-quality water for applications worldwide including industry, agriculture and drinking water. IDE adds that PROGREEN overcomes the challenges of minimising desalination impact on the environment by eliminating the use of chemicals in the pre-treatment and desalination processes. The new water production system is compact and flexible, which makes it easy to transport and install. This significantly reduces costs and eliminates the need to invest in expensive infrastructure. In addition, as part of the desalination process, the patented RO Membrane Direct Osmosis Cleaning (DOC) system reduces the amount of energy consumed in the desalination process, and enables chemical-free membrane cleaning for uninterrupted operation and stable performance, which increases the system’s availability. According to IDE, PROGREEN helps to further save money by utilising highly efficient pumps, coupled with an energy recovery system, to reduce energy consumption. The modular product is designed for capacities ranging from 500 to 10,000 cubic metres per day per unit, depending on water type; and is available containerised or skid-mounted, depending on the capacity. The new IDE PROGREEN system will be available by the end of 2011. www.ide-tech.com
Key benefits of the innovative HYDRAcap® MAX technology include: lower capital and operating costs; increased reliability; the ability to treat challenging waters; and simplicity of operation. The new elements include the HYDRAcap® MAX 80 with a surface area of 105m2 and HYDRAcap® MAX 60 at 78m2. www.membranes.com The IDE PROGREEN system will be available from the end of 2011.
NanoH2O NanoH2O has added a new seawater reverse osmosis (SWRO) membrane to its high flux, high rejection QuantumFlux product line. The membrane is claimed to be highly productive and energy efficient. This new SWRO membrane, the Qfx SW 400 ES, features 37 square meters (400 square feet) of active membrane area with a permeate flow rate of 52 cubic meters per day (13,700 gallons per day). The Qfx SW 400 ES offers good salt rejection and was recently awarded NSF Standard 61 Certification for the safety and viability of thin-film nanocomposite (TFN) membranes when used for the production of potable water. Also new to the NanoH2O product line is an innovative anti-telescoping device (ATD) designed for durability and ease of use. By the end of 2011, all of NanoH2O’s QuantumFlux 8-inch SWRO elements will incorporate this new ATD. Features include: • New rib design for added durability. • Lip feature for easier membrane removal from the pressure vessel. • Convenient bi-directional brine seal that allows installation and removal of membranes from either end of the pressure vessel. • Gutter feature under the brine seal to equalise pressure. • A new ATD seal plate design to visually distinguish Qfx membranes. www.nanoh2o.com
Nitto Denko/Hydranautics Nitto Denko/Hydranautics has introduced new microfiltration elements based on HYDRAcap® MAX technology to treat highly challenging waters. HYDRAcap® MAX microfiltration technology provides a high membrane surface area, which results in ultra low footprint and minimises capital costs. The crystalline PVDF membrane fibre is extremely strong and durable, resulting in minimal fibre breakage, greatly reducing operating costs while maintaining optimal filtration performance. Additionally, HYDRAcap MAX can operate at high fluxes without the need for backwash and with minimal cleaning, resulting in high water recovery.
Dow Water & Process Solutions Dow Water & Process Solutions highlighted new and advanced technologies in a number of areas at the World Congress. Reverse Osmosis (RO) and Nanofiltration (NF) membrane technology (FILMTEC™ membranes) enable a wide variety of industrial, municipal, commercial and home drinking water applications. The company’s 16-inch diameter RO modules contain nearly four times the membrane of market standard 8-inch modules, and lower the cost of capital required for desalination systems by 10 to 20 percent. DOWEX™ ion exchange resins include a broad line of products for use in industrial processing water, drinking water, food and pharmaceutical processing and power generation. Catalysts, such as DOW™ AMBERLYST™, offer fuel developers the flexibility to produce biodiesel from more than 30 different feedstocks including crude animal fat without yield loss, acids or waste. Pressurised Ultrafiltration (DOW™ UF) technology is a membrane separation system that is often used as a pre-treatment to reverse osmosis (RO) purification. The DOW™ Ultrafiltration SFP-2880 element design has 50 percent more membrane active area in a smaller, more compact membrane design, shrinking the overall system footprint by as much as one-half. DOW™ EDI Electrodeionization Technology is a cost-effective and environmentallyfriendly alternative to post-RO deionisation applications. The DOW™ EDI module employs a leak-free and low maintenance spiral wound design housing membranes and ion exchange resins. DOW™ EDI modules are claimed to optimise performance, maintain continuous product quality and can produce up to 18 MΩ-cm of high purity water with high silica and boron rejection. www.dowwaterandprocess.com

Nalco Nalco introduced a new solution for improving performance, reducing the total cost of ownership and shrinking the environmental footprint of industrial reverse osmosis (RO) systems. The launch of 3D TRASAR Technology for Membranes was announced at the IDA World Congress. “3D TRASAR Technology for Membranes improves the operation of RO systems and yields a variety of sustainability benefits for our customers,” said Erik Fyrwald, Nalco chairman and chief executive officer. “It cuts water consumption, wastewater production, energy use and chemical treatment use, all while extending the life of the RO membranes.” According to Nalco, the technology is a completely integrated solution that includes patented TRASAR® technology for accurate feeding and dosing, membrane system performance monitoring, and a comprehensive service package. The automation and Nalco 360 Service Expert Center advice enables ‘service on demand’, avoiding unnecessary cleaning while ensuring cleaning is performed before membrane performance is irreversibly reduced. In applicable geographies, Nalco will provide membrane cleaning services and provide replacement membrane elements. A new approach to oxidation reduction potential monitoring, alarming and response provides a reliable extra layer of protection against accidental chlorine damage to the membranes.
3D TRASAR Technology for Membranes also includes proprietary, green antiscalants designed to improve membrane life while minimising environmental impact. One of the new antiscalants is specifically designed to reduce or eliminate the use of high quantities of acid in treating RO systems operating on high phosphate feed waters, such as municipal wastewater, reducing operating costs, improving employee safety, and conserving high quality water resources for human consumption. A second antiscalant replicates the performance of Nalco’s existing high-performance scale inhibitors, but with no phosphorus in the formulation. This allows customers to better meet new discharge regulations designed to prevent algae blooms in lakes and streams that can harm fish and other aquatic life. “Integrated solutions provide customers with the best combination of equipment, chemistries, and services to solve problems most cost effectively,” says Dr. Manian Ramesh, Nalco Chief Technology Officer. “With 3D TRASAR Technology for Membranes, it’s possible to safely operate membrane systems at higher recovery, optimising performance, water quality and reliability. Customers not only reduce operating costs by 5 to 15 percent or more, they can shrink their environmental footprint, providing them eROI, an environmental return on investment”.
