INTERNATIONAL COOPERATION ON WATER SCIENCES AND RESEARCHImage: KICTThe packaged water treatment system in Ulaanbaatar, MongoliaHyundai Engineering develops a remote monitoring and decisionmakingsystem based on IT technology for the operation andmanagement of water treatment processes in Sri Lanka. KICT developssmall-scale, movable, decentralized water treatment packagesystems for developing countries and natural disaster preparation.The packaged water treatment system is being tested in Mongolia tooptimize its operation conditions.Through strategic projects, the centre expects to develop a functionaland intelligent integrated waterworks system and to increasethe applicability of environmentally-friendly technology based onIT-ET technologies. It is also expected that energy saving technologiesleading to low carbon economy will be developed.The Yeongdeungpo membrane system in Seoul, KoreaThe Yeongdeungpo membrane system is a water treatment systembased on membrane filtration processes replacing sand filtrationto produce good quality drinking water. It was completed in 2010through the joint efforts of the Ministry of Environment Korea,Seoul Metropolitan Government and private enterprises (DaewooE&C and Hanwha E&C).Daewoo Integrated Membrane System (DIMS) technologyproduces safe and reliable drinking water by removing pathogenicmicrobes and other hazardous matter from the raw water using apressurized membrane filtration system. This system is suitable forthe improvement of old plants to meet the reinforced drinking waterquality standard. The Yeongdeungpo membrane system has a capacityof 25,000 m 3 per day and has been producing quality drinkingwater for Seoul citizens since April 2011. It purifies raw water takenfrom the Han river by mixing, coagulation/flocculation, sedimentation,microfiltration, ozone oxidation, granular activated carbon(GAC) adsorption and disinfection processes.The Hanwha Technology Membrane (HTM) water system is anadvanced water treatment technology for drinking water productionbased on membrane filtration with a capacity of 25,000m 3 per day. It consists of an inline mixer, coagulationtank, submerged membrane tank, ozone tank and GACtank. The system is highly efficient, compact and haslow energy consumption compared to conventionalwater treatment systems.The system decreases turbidity up to 0.5Nephelometric Turbidity Units for treated water andcompletely removes pathogens such as Cryptosporidiumand Giadia from raw water. It also significantlydecreases the concentrations of taste and odour-causingsubstances such as 2-MIB and geosmin in drinkingwater to less than 10 ng/L, meeting the drinking waterquality standard of Korea.Hybrid membrane technologies such as DIMS andHTM can reduce not only the use of chemicals (such ascoagulants) by over 50 per cent compared with conventionalsand filtration; they can also reduce energy costsby up to 15 per cent by optimizing operating conditionsand management work.Since 2011, Daewoo E&C and Hanwha E&C havecontinued core research and development work on theEco-Smart Project, to optimize the technology of largescalewaterworks systems based on a total solution fordesign, construction and operation. Daewoo E&C andHanwha E&C worked with the Seoul MetropolitanGovernment to optimize operation technology at theYeongdeungpo drinking water treatment plant. An integratedwaterworks management system was established,networking the new membrane system and existingsand filter in order to improve unit operation functionand data management. In addition, the diagnosis functionof the membrane system, including membrane[ 313 ]
