China Communications Construction Company Limited ("CCCC" ), initiated and founded by China Communications Construction Group ("CCCG"), was incorporated in 2006. Its H shares were listed on the Main Board of Hong Kong Stock Exchange in 2006. The Company (including all of its subsidiaries except where the content otherwise requires) is the first large state-owned transportation infrastructure group entering the overseas capital market. Among 127 central enterprises governed by SASAC, CCCC ranked No.12 in annual revenue.The Company and its subsidiaries are principally engaged in the design and construction of transportation infrastructure, dredging and heavy machinery manufacturing business. It covers the following business aspects: port, terminal, road, bridge, railway, tunnel, civil work design and construction, water and wastewater treatment works, capital dredging and reclamation dredging, container crane, heavy marine machinery, large steel structure and road machinery manufacturing, and international project contracting, import and export trading services. It is the largest port construction and design company in China, a leading company in road and bridge construction and design and etc. The Company is also the world's largest container crane manufacturer. The Company currently has 34 wholly- owned or controlled subsidiaries.
Beijing OriginWater Membrane Technology Co., Ltd. was founded in 2001 and is a part of CCCC Group. The company is located in Huairou Science Park, Beijing. Integrated with top-ranking R&D team, cutting-edge experimental instruments, advanced automatic production equipment, the company is dedicated in R&D, production and sales of reverse osmosis, nanofiltration membrane products and membrane manufacturing systems and providing overall solutions for "remediation of the water environment, development of new water sources, protection of drinking water safety and urban ecological environment construction" through membrane technology.
Now, Beijing OriginWater Membrane is equiped with 70 lines for hollow fiber membranes (MF & UF), 2 lines for corrugated membranes (MF), 8 casting & coating lines of nanofiltration and reverse osmosis (NF/RO). We also do the automatic rolling of domestic and industrial spiral wound membrane elements, hollow fiber modules and units alignment, water treatment systems and domestic and commercial water purifiers manufacturing.
Taking the reinforced polyvinylidene fluoride (PVDF) hollow fiber membrane with independent intellectual property rights as the core, the SUF(Submerged Ultrafiltration Membrane Module) solves the problem that the ultrafiltration membrane is prone to get broken in engineering applications and the module is featured with high effluent quality and strong fouling resistance. The product is one of the significant achievements in Major Science and Technology Program for Water Pollution Control and Treatment during "the 12th Five-Year Plan",and it has been selected as National Torch Plan Project and the Major Environmental Protection Equipment Encouraged by the State, and has been awarded with the New Technology and New Product in Zhongguancun, the Beijing New Technology and New Product, etc.
Features of the submerged ultrafiltration membrane modules
Excellent effluent quality:
Narrow membrane pore size distribution, high filtration precision, more than 6log of bacterial retention rate, more than 41og of virus retention rate;
Easy cleaning and maintenance:
Due to composite hydrophilic modification technology, the membrane be preserved at dry state, and it is convenient to be stored, transported, cleaned and maintained;
Strong fouling resistance:
Due to special gradient networked pore structure of the membrane and uniform water and air distribution structure in the unit, membrane fouling can be effectively prevented and controlled;
Long service life:
strength of membrane is more than 100N and the life is more than 5 years.
