waterwaterPentair Haffmans CO 2system equipsdesalination plant in ChinaIntroducing CodeLinemembrane housingswritten by roy speePentair Haffmans is supplying its first carbon dioxide (CO 2) injection system to adesalination plant in China. The 13 million gallons per day (50,000 m 3 /d) seawaterreverse osmosis system (SWRO) is located in the Caofeidian Industrial Zone near thecity of Tangshan and part of a large-scale governmental construction project.Since 1977, Pentair’s CodeLine ® has setthe standard in the membranehousing industry. Every productof world leading CodeLineSeawater Reverse Osmosis is a leading process fordesalination. While the characteristics of RO membranesare ideal for removing the salt, they also removeminerals from the water. As a result, after RO membranetreatment the water is not suitable for consumption.A post-treatment to re-mineralize the water isrequired.The Pentair Haffmans’ CO 2dosing and injection systeminstalled at Caofeidian, 136 miles (~ 220 km) fromBeijing, contributes the re-mineralization process as itadds CO 2to the permeate flow during post treatment.To make RO water drinkable, water leaving the ROmembranes is carbonized so that minerals can be dissolvedat the calcite filters. Pentair Haffmans’ CarboController side stream carbonation system automaticallyand accurately doses the CO 2into the water todecrease the pH value. This allows the calcium ion torecreate some hardness and alkalinity in the water, asrequired by the World Health Organization standards.Carbon dioxide is an ideal solution as it is a non-toxic,non-hazardous drinking water additive that replacestoxic chemicals such as calcium chloride or sodiumhypochlorite, which are becoming obsolete. Striving forsafe, environmentally friendly and efficient solutionsis an integral part of the Pentair philosophy.“This project is a great accomplishment for PentairHaffmans,” said Olaf Müller, Pentair HaffmansManaging Director. “Our expertise in carbondioxide and oxygen management as well as gas treatmenttechnologies gained from the beverage industryhas helped us to move into new markets. The Chinesemarket for desalination is one of the fastest growingworldwide.”Aqualyng Norway, in conjunction with joint venturepartner Tangshan Caofeidian Infrastructure ConstructionInvestment Co. (IIC), developed and will operate thedesalination plant. Hangzhou Development Center ofWater Treatment Technology Company was chosen tobuild the plant.The Caofeidian Industrial Zone, owned by the Chinesegovernment, is on China’s list of pilot areas for sustainableeconomy. According to the construction plans, theentire industrial zone will cover an area of 124 squaremiles (~ 310 km 2 ) by 2020. Goals are high in terms ofecological and economic sustainability, including theconstruction of a climate-neutral eco-city, offeringspace for a population of approximately one millionpeople.brand is conceptualized, designedand manufactured tomaximize the efficiency andperformance of water purificationsystems.Housings sizes, ranging from 2.5, 4.0, 8.0, 11to 16 inch in diameter, are available to suit criticaland demanding applications including desalination, reverse osmosis, nanofiltrationand ultrafiltration. CodeLine housings fit any make of standard membranes.CodeLine has many firsts to its credit and technologies including Side-port or Multiports,which were introduced by CodeLine, revolutionized the membrane housingindustry. CodeLine focuses on developing products that bring the most benefit to itscustomers including reducing energy cost in desalination and making membranetechnology cost competitive. These are just a few of the reasons why most of themajor global membrane-based projects use CodeLine.CodeLine has two manufacturing facilities in Goa, India and Suzhou, China, and itsproducts carry the most quality accreditations in membrane housing industry,including ISO, ASME, CE, NSF, and DWI.Brazilian bioethanoldistillery equipped withCO 2recovery plantfrom Pentair HaffmansUsina Vale awarded a contract for a Pentair Haffmans carbondioxide (CO 2) recovery system to Pentair Water do Brasil. Thebioethanol distillery, located in São Paulo State, producessugar and alcohol and plans to sell the recovered CO 2.The CO 2source is a sugar cane distillation process that produces bioethanol.The CO 2recovery system will enable Usina Vale to reduce CO 2emissions whilegenerating an additional source of income. The system was commissioned inAugust of this year with an initial capacity of two metric tonnes per hour.Usina Vale is able to sell recovered CO 2for beverage and food applications.Moreover, the inclusion of a highly efficient Pentair Haffmans gas washerallows them to recover more ethanol from the CO 2stream – thus reducing theproduct losses. “This is a great step for us,” said Brazilian based Sales ManagerMarcelo Rampazzo. “This first Pentair Haffmans CO 2recovery plant in Brazilwill open many doors, not only in the distillery market but also in the brewingindustry.”10 knowhow 2011knowhow 2011 11

pumpsPump supply for the Huascacocha water transfer project in PeruPentair Nijhuis’ first pumporder in South Americawritten by inge sluijterPentair Nijhuis’ pumps have been selectedas part of the water transfer system to feedthe Peruvian Huachipa drinking watertreatment plant benefitting 2.4 millionresidents in Lima and neighboring Callao.Pentair Nijhuis received an order from theBrazilian construction firm ConstructoraOAS Ltd. for the supply of four 855,000gallons per hour (3,240 m 3 /h) capacity splitcase pumps for this project.The project includes building a 49 foot (15 m) dam wallthat will store almost 21 billion gallons (79million m 3 ) of water and building 14 miles (22.5 km) ofconcrete channel, a 1.3 mile (2,1 km) tunnel and a 3.2mile (5.1 km) long pipe line that is 4.9 feet (1500 mm)in diameter. The water transfer system leads from theHuascacocha Lake, via the Marca III system, to theRímac River in Lima, Peru. The end customer of thisproject is Sedapal, Peru’s state-controlled water utility.“From the Huascacocha facility the Pentair Nijhuispumps feed the Huachipa drinking water plant with acapacity of up to 695 gallons per second (2.63 m 3 /s),”said Damián Sciarra, Product Manager at Pentair’sArgentina sales office. “OAS chose Pentair Nijhuis’pumps, based on low energy consumption and low lifecycle costs for operation over a 25-year period.”“The combined efforts of our partner Enerquímica inPeru, colleagues in the Argentina sales office andPentair Nijhuis to penetrate the South American pumpmarket resulted in the first pump order in this continent,”concluded Frans Staring, Senior Area SalesManager, Pentair Nijhuis.KnowHow Published byPentair Water ProcesTechnologie Holding BVP.O.
