Algeria Adds 200,000 m3/day of Increased Seawater Desalination Capacity
SAN LEANDRO, Calif.--(BUSINESS WIRE)--Sept. 24, 2008--Energy Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of ultra-high-efficiency energy recovery products and technology for desalination, announced that it had won another large-scale energy recovery contract for seawater reverse osmosis (SWRO) desalination in Algeria. The Mostaganem SWRO Desalination Plant, located approximately 38 miles east of Oran in the western seaside region of the country, will have a total capacity of 200,000 cubic meters per day (m3/day) (52.8 million US gallons per day), enough to supply drinking water to a population of over one million people. The plant is expected to begin operation sometime in the second half of 2009.
The Mostaganem plant is being built on a 25-year build own operate and transfer basis by UTE Mostaganem, a consortium consisting of Inima (Grupo OHL) and Aqualia (Grupo FCC) of Spain. Inima previously selected ERI to provide its advanced energy-saving PX technology for both the 16,000 m3/day Los Cabos and 65,000 m3/day Alicante desalination plants. The Mostaganem project is one of many for ERI in the region, including the 200,000 m3/day Hamma plant built by GE Water and the 200,000 m3/day Beni Saf and 100,000 m3/day Skikda plants currently being built by GEIDA.
The process for the Mostaganem plant will include 240 ERI PX-220 Pressure Exchanger devices arranged in 16 trains of 15 units each. Utilizing PX technology will help significantly reduce power consumption by the plant's high-pressure pumps. Each device will save approximately 80 kilowatts for a total plant energy savings of over 19 mega watts.
Rick Stover, ERI's Chief Technical Officer and Vice President of Sales said, "with this contract, ERI increases its project wins in Algeria to 1,220,000 m3/day of permeate capacity. We are proud to be the energy recovery solution for the region."
140,000 m3/day (37MGD) Desalination Project for Mining Application Contracted to use PX(R) Technology
SAN LEANDRO, Calif., Oct. 2 /PRNewswire-FirstCall/ -- Energy Recovery, Inc. ("ERI") (Nasdaq: ERII), a global leader of ultra-high-efficiency energy recovery products and technology for desalination, announced that it will supply energy recovery devices for a seawater reverse osmosis (SWRO) desalination project in Australia. IDE Technologies awarded ERI the energy recovery contract for the 140,000 cubic meters per day (m3/day) (37 million gallons per day (MGD)) facility. The new desalination project adds process and drinking water for a large mine operation in Australia.
IDE Technologies will construct the plant which will utilize ERI's PX Pressure Exchanger(R) (PX(R)) technology as the energy recovery solution for the project. The plant is scheduled for completion in late 2009.
Water is a key component in the mining process. Because the region is subject to extreme drought conditions, a highly efficient desalination system provides an affordable solution both for process requirements and regional drinking consumption. The ERI solution will include PX-220 devices which will save an estimated 16 megawatts of power.
In 2007, ERI was also engaged for a 55,000 m3/day (14.5 MGD) desalination plant for the Trekkopje Uranium project in Namibia, South Africa. That plant is projected to supply an estimated 20 million cubic meters of water per year to the mine. In addition, ERI and IDE Technologies are teaming to provide advanced energy-saving PX technology for the 100 million m3/year Hadera, Israel desalination plant which will be the world's largest such plant when it starts up in 2010.
The sand screens and micron filters were selected because of the durable and corrosion resistant fiberglass and PVC construction. The specific model of Eden micron filters was chosen to maintain the filter element flux at approximately 3.3 gpm/per 10" equivalent.
Due to the relative remoteness of the installation site, multistage-centrifugal, high-pressure pumps have been selected for their reliability, availability of parts, economics of operation and easy maintenance. Centrifugal pumps in general are smoother, quieter, and require less ancillary equipment (i.e. pulsation dampeners) than positive displacement pumps. Hydropro has found that positive displacement pumps are much more prone to failure and lengthily downtimes than high-quality centrifugal pumps.
The Grundfos Booster Modules were chosen for several reasons. The inline style helped conserve space and provided ease of installation, allowing everything to be mounted on the same skid (with the exception of cleaning/flush tanks, raw water booster pumps, and chemical feeds). These submersible, multi-stage centrifugal pumps were also chosen because they are very efficient and quiet, and are constructed of corrosion resistant, 904L super austenitic stainless steel.
The high pressure feed and concentrate headers were made of 2205 duplex stainless steel for superior corrosion resistance, and the structural skid was constructed of FRP for low weight and zero maintenance. ERI´s Pressure Exchanger was chosen because of its high energy efficiency, dependability, and corrosion resistant materials.
Values for the projected power consumption rates that were presented in the proposal were based on a 27ºC feed stream of 45,000 mg/l TDS and a permeate flow rate of 100,000 gpd. The membrane manufactures projection software was used to determine the system parameters at a recovery of 35%, and these parameters were subsequently used to determine the projected power consumption. The result was an anticipated feed pressure of 900 psi and a specific power consumption rate of 3.02 kWh/m³.
Once the system was installed and operating, the specific power consumption was calculated based on actual system parameters and the result was a much lower value of 2.65 kWh/m³. There were several reasons the actual value was lower, the main reason however, was the conservative design. Because of some uncertainty in the feed water quality, the SWRO system was designed with a relatively low flux (approximately 8 gpm/ft2), and a somewhat large hydraulic envelope. As it turned out, the feed water TDS was closer to 36,000 ppm and fairly stable. The lower feed TDS enabled the system to operate at a lower membrane feed pressure of 790 psi and a higher permeate flow rate of 120,000 gpd, consequently using less energy than originally projected and making higher quality permeate.
With most of the system assembled, the installation was fairly straightforward and went smoothly. The two units were installed, started up, tested and operator training was completed in less than three weeks. There was, however, a problem with the feed water quality and the pretreatment system, which was discovered after only 24 hours of operation. It immediately became apparent that the raw water was loaded with particulate that was quickly fouling the sand screens and the micron filters. Fortunately, the feed system could be modified to flow into an existing 250,000 gallon seawater tank from the wells, and the SWRO feed was then drawn out of this tank. This settling tank solution worked quite well and provided a feed water with a pre-filter SDI of 1.25.
There was also one other performance issue that needed to be resolved. Initially, the permeate quality was less than what was projected, and it was not clear why. The system was extensively checked ant tested for leaks, and the possibility that seawater was somehow mixing with the permeate was eventually eliminated. It was finally determined that the membranes did not meet the design rejection required to produce the projected permeate TDS. Once the membranes were replaced, the system was making plenty of high quality permeate that was well below the maximum acceptable permeate TDS.
KAJUR and the residents of Ebye have since been enjoying low-cost, high-quality water for over a year now without any noteworthy system failures. They are so pleased, in fact, that KAJUR has recently awarded Hydropro another SWRO job utilizing work exchanger energy recovery.
