It was learned from the China Film Industry Association that the “Twelve Five Development Plan for Separation Membrane†initiated by relevant departments has been completed and will be issued in the near future. It is understood that the sewage treatment, water purification and reclaimed water treatment and other water industry sectors in the major sub-sectors, the industrialization of development must adopt the separation membrane processing technology that has gradually become the mainstream of the market. The relevant analysis predicts that during the “Twelfth Five-Year Plan†period, the market demand for tap water separation membrane treatment will reach 1.2 billion yuan, while the market for sewage treatment and reclaimed water biofilm processing will reach 100 billion yuan. Membrane materials and engineering will independently embark on the path of industrial development.
The tap water membrane treatment refers to the process of adding membrane treatment processes to make it more clean on the basis of the traditional tap water treatment process (flocculation-precipitation-disinfection). Zhao Jialian, secretary-general of the China Environmental Protection Industry Association's Water Pollution Management Committee, told reporters earlier that most domestic water plants and sewage treatment plants use traditional techniques for water treatment. This type of technology not only has a large project investment, but also has a long construction period. The most critical point is that the treated effluent water quality cannot meet the requirements of the relevant national standards. From the current point of view, the membrane treatment technology and technology can exactly make up for the defects of the traditional process, and at the same time, the treatment effect meets the requirements of various water quality standards.
Taking tap water purification as an example, it is understood that tap water treatment with separation membrane has the features of stable operation and high effluent quality, and is suitable for solving the current situation of serious increase in drinking water standards and serious water pollution in China.
According to experts from China Water Network, algae problems have become a common concern for urban water plants. It is difficult to remove algae in water by traditional techniques, and membrane technology can be easily implemented. Microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, for example, have gradually become mainstream processes for urban clean water and wastewater treatment.
At present, 90% of domestic reverse osmosis membranes are imported products, about 40% of ultrafiltration and microfiltration membranes are imported, and 50% to 70% of the raw materials used to make membranes are imported. To this end, the “12th Five-year Development Plan for Separation Membrane†(Draft) proposes that during the “Twelfth Five-Year Plan†period, China must establish a complete and large-scale production technology and production of membranes and membrane modules in the entire field of separation membranes. Capacity, membrane performance has reached the international advanced level.
Ping An Securities analyst, relative ultrafiltration membrane, nanofiltration membrane has a good effect of removing heavy metals; and relative reverse osmosis membrane, nanofiltration membrane can leave most of the mineral ions. Therefore, in foreign countries, nanofiltration membranes are the main separation membrane for mainstream drinking water treatment.
Xiao Ye, an analyst at Zero2IPO Research Center, told reporters that in the past few years, the membrane water treatment technology has had difficulties in promotion because of the high cost of membrane materials, membrane reactors, and regular maintenance costs. However, as energy prices rise, the advantages of low energy consumption in the membrane separation process are reflected.
According to the latest data from the Ministry of Housing and Housing, China’s daily water supply capacity in 2011 was 270 million tons. The above Ping An Securities analyst said that if the proportion of 2% is calculated, the membrane processing volume is about 2.34 million tons / day. Considering the economic conditions of public utilities and the “Twelve Five Development Plan for Separation Membrane†(Draft), it is expected that by 2015, China's tap water membrane capacity will reach 920,000 tons/day, and the separation membrane market will increase by 500 million yuan. 17 billion yuan.
In the field of sewage treatment, biofilm processing technology is gaining recognition in the industry. According to statistics from Tsinghua University, the market share of China's MBR project in 2004 was about 40 million yuan, and by 2008 it would have reached a scale of more than 1.6 billion yuan. According to relevant market forecasts, with the increase in water quality standards for wastewater treatment, the demand for sewage treatment on membrane materials and the engineering market in the next five years will reach 10 billion yuan.
The relevant experts of the China Film Industry Association predict that during the “Twelfth Five-Year Plan†period, the demand for the national separation membrane will increase by 25%-30% per year.
In the A-share market, many companies' membrane business has begun to make a full force. Bishuiyuan is currently building an annual production capacity of 2 million square meters of PVDF hollow fiber microfiltration membranes and an annual output of 1 million square meters of hollow fiber ultrafiltration membrane production lines to achieve fully self-sufficient membranes. With this as a driving force, the company's sewage treatment and water purifier gross profit margin reached 49.91% and 75.15%, respectively.
And another company that produces reverse osmosis membranes, South Huitong, analyzes that it currently has 3 million square meters of reverse osmosis membrane production capacity, accounting for 10% of the domestic market share, and product gross margin of 40%.
