1. EGI - Contracting Engineering Co. Ltd. Industrial Water Treatment Plants – Balance of Plant Systems MEMBRANE-TECHNOLOGY BASED LARGE SCALE WATER TREATMENT PLANT IN TISZAÚJVÁROS IN HUNGARYCLIENT:TVK Hungary’s Largest Chemical Company Energy Technology Division • Project background • Tiszai Vegyi Kombinát Rt (TVK), Hungary’s largest chemical company and its only polyolefine producer is located at North-East Hungary near the Tisza river. The company that accounts for more than 20 per cent of the petrochemical capacity of Central Eastern Europe is the largest industrial heat and salt-free water consumer of Hungary. To cover the increasing water demand of the company – including that of its embedded power plant - and to substitute the existing obsolete water treatment plant, a new 3x150 m3/h capacity water treatment facility has been decided to be built based on current state-of-the-art membrane technology. Industrial Water Treatment Plants • 2. Water Treatment Technology • Raw Water System • ZeeWeed® Ultra-filtration System • Reverse Osmosis System • Final Polishing System (Mixed-Bed Ion Exchangers)
