MBR's largest market in China

China's huge water market attracts more and more companies to join it. The MBR technology, as one of the sewage treatment technologies with rapid rise in China in recent years, has brought a vast business opportunity to the film industry. While the industry’s cutting-edge companies have emerged more and more, many established domestic and foreign manufacturers have also increased the speed and intensity of China’s layout. As far as the sewage treatment industry is concerned, industry insiders say that nowadays, MBR technology can be described as a matter of course. People who engage in sewage treatment technology are proud to study MBR. If a sewage treatment person has not heard of MBR, it may Many people laughed. It can be seen that this technology has brought great impact on the sewage treatment industry.

The special survey of “Using the MBR Process Sewage Treatment Project” also showed this concern.

MBR technology contends "single weapon" of sewage treatment industry

The reason why MBR technology has become such a high enthusiasm for everyone is that it is not unrelated to its own characteristics. In an interview with China Water Network, He Yuanping, executive vice president of Beijing Clearwater Technology Co., Ltd., said that some features of MBR technology are the most critical. First, the MBR process occupies a compact area, the high sludge concentration allows it to complete the processing function in a smaller reactor space, and there is no sedimentation tank at the same time, and the land occupation is inevitably small. Second, the effluent quality of the MBR process is very good. The effluent quality of the technology is clearly unmatched by gravity sedimentation. The situation of our country's water environment is so severe that the MBR's effluent quality indicators can reach Grade III surface water quality, with a COD of 25-30 mg/l, and the national Class A emission standard requirement is 50 mg/l. Third, the sludge is reduced by more than one third. In the fourth, the operation is relatively simple because the equipment is operated through automatic control.

Experts from the sewage treatment industry also stated that water quality parameters such as turbidity, COD, BOD, and NH3-N of the MBR effluent can meet most of the reuse requirements; while other treatment technologies either occupy a small area or have good effluent quality while satisfying These two technical characteristics of the process are few. These two technical characteristics are exactly the contradictions that must be resolved in our country's social development. With the rapid development of urbanization, land has become the most valuable commodity, and the pursuit of a beautiful water environment is also an urgent desire of the public. It is inevitable that MBR technology will be favored in such an era.

From the point of view of the development of the water industry technology, He Wanping believes that the MBR has brought about a revolution in the environmental protection industry. Traditionally, sewage treatment plants are more of a project, more than 70% are civil works, and all kinds of tanks are built, only 20-30% of the equipment. MBR changed this approach: more than 70% are equipment and 20-30% are civil works, which is the root cause of the small footprint of MBR sewage projects. Therefore, compared with the traditional technology, the construction time of the MBR project is much shorter, and the larger-scale projects in time can be completed within 4-6 months. He said that the development of the industry, one is the development of services, the second is the development of technology and equipment.

MBR's largest market in China?

In view of the MBR technology market in China, Asahi Kasei Group Marketing Minister Zhang Gang told the China Water Network reporter that MBR technology can be widely used in municipal sewage, industrial (chemical, paper, food) wastewater, landfill leachate and other fields. In fact, numerous international companies including Asahi Kasei, GE, and Siemens have large-scale MBR process performance in China. The application of MBR in China is relatively larger, the number is relatively more, and the prospects are wider than other countries. The reason is that China, especially in the northern regions, is extremely water-deficient and has high demand for recycled water, while membranes are used for the recycling of sewage water. The effect is relatively good and the technology is relatively mature, making China destined to become the largest market for the global MBR. In this regard, He Yuanping believes that, in addition to the north of the reclaimed water reuse demand, the southern region for the consideration of MBR technology is more for the purpose of emission reduction; sewage treatment plant to bring the standard transformation to MBR technology opportunities.

This coincides with the view gained by the reporter of China Water Net when interviewing other people in the industry. According to a survey conducted by the China Water Network MBR Special Survey Group, up to now, there are more than 50 MBR engineering projects with a scale of over 10,000 tons/day (including construction) in China's wastewater treatment projects, with clear water sources, GE, and Nuo. The companies represented by Wei and Asahi Kasei have promoted the large-scale application of MBR technology in the municipal wastewater field.

The "MBR Rivers and Lakes" of China's Ten Thousand-Yuan Municipal Projects

According to a survey by China Water Network, Clearwater has built 11 million-ton or more MBR projects, 5 million-ton or more MBR projects under construction, and 7 million-plus-million-mega-project MRT projects have signed agreements or contracts, with a total scale of 1.195 million. t/day. These projects mainly include reclaimed water and municipal sewage treatment. They also include rainwater and river water treatment projects.

It is reported that Bishuiyuan is now one of the few companies in the world that can produce film silk with a tensile strength of more than 200 Newtons. For this, Wu Pingping is very proud. He said humorously: To treat a patient, it is necessary to have a doctor and a drug. For the MBR sewage treatment project, the “medicine” is the membrane and membrane module. The “doctor” is the process technology. The good doctor has no good medicine and cannot cure the disease. There are good medicines that do not work well for doctors. A company must have such a level, both doctors and drugs. In the past, Bishuiyuan's projects mainly used foreign medicines and were themselves “doctors”. Now they can also do “medicine”. To make medicines on their own, the doctor knows what adjustments the medicine needs to make based on the information returned, and the two are related.

Since entering the Chinese market in 2006, Asahi Kasei Group has also provided membrane products for a number of municipal wastewater treatment plants with a capacity of over 10,000 tons and large-scale petrochemical wastewater treatment facilities in the Chinese market, including: 2006 Beijing Water Group Huairou Sewage Treatment Plant 35,000 tons/day, China National Offshore Oil Daya Bay Refinery 40,000 tons/day, Sinopec Hainan Refinery 10,000 tons/day, 2007 Beijing Pinggu Wastewater Treatment Plant 40,000 tons/day, Wenyu River Beijing Shunyi Water Park The 100,000-ton/day project will be completed soon after the company's sewage treatment plant renovation project in Dongcheng District of Daqing City, Heilongjiang Province, will process 50,000 tons of sewage every day. In addition, Asahi Kasei Group also provides products for many thousand-ton and hundred-ton MBR projects each year.

In addition, more than 10,000 tons of municipal projects include the Kunshan Lujia Sewage Treatment Plant built by GE, the Meicun Water Treatment Plant of Wuxi Gaoxin Waterworks Co., Ltd., the second phase of the Wuxi Xincheng Water Treatment Plant built by Siemens, and the sewage from Beihe River. The treatment plant will be redeveloped and expanded to use the reclaimed water project. The Guangzhou Jingxi Sewage Treatment Plant (used by Singapore's Meineng company's membrane products) built by Nuowei etc.

Opportunity Brings Competition: While membrane companies are pulling over China’s huge water market to bring business opportunities to membrane companies, competition in the market is fierce, and competitors in the industry are constantly emerging. In 2010 alone, dozens of new membrane companies emerged in the industry. Because China has a strong human resource advantage, R&D and production costs are relatively low, and the domestic membrane product price advantage cannot be ignored. The advantages of domestic membrane manufacturers Also increasing. Of course, companies that have a long history in the field of membranes have their own advantages. The development and application of the company's products have undergone long-term tests. For example, some established companies have numerous actual operating performances in the fields of water purification technology, sewage treatment, wastewater reuse, etc., and have gained rich experience based on these achievements and formed a complete technical support for design consultation, after-sales service, and so on. System, this is all the development advantages that companies have.

As for the competitors of the clear water source in the MBR market, He Pingping did not say anything. He said that the first was GE and its agents, the second was Siemens, and the third was Novo (joint environmental protection). He believes that the core advantages of the clear water source are, first of all, price advantages; followed by the provision of full-service, from the design start until the completion and later operation guidance; Third, better understanding of the situation in China, investment and operating costs Lower. He emphasized that the high or low operating costs are related to engineering experience and operational experience. Clearwater sources have already explored a set of experiences.

In recent years, in the field of municipal sewage and industrial wastewater, some of the larger projects still use membrane products from foreign manufacturers. In view of the high price of foreign products, Zhang pointed out that although the overall price of foreign products is relatively high, the owner can not only consider the price of the film product when selecting the product, but also should comprehensively deal with product life, vendor technology and existing performance. consider. For Asahi Kasei Group, the main competitors are GE, Siemens, Clearwater, and Meineng. In 2010, Asahi Kasei Group was one of the two strategic pillars for the “expansion of internationalized business”. In China, it will strengthen its marketing activities in China, use the advantages of Asahi Kasei Group, continue to promote the localization of business and marketing methods, and work closely with local companies to increase efforts to open up the Chinese market.

MBR: To heat, do not have a fever to understand a technology not only to understand its advantages, but also to understand its shortcomings and limitations of its objective conditions.

The development of any new thing will inevitably experience failure, and the accumulation of failures will become an experience. MBR is no exception. For MBR, Clearwater believes that the biggest problem is power consumption. He Yuanping told the China Water Network reporter that MBR has experienced many difficulties in its promotion and application because it is a new technology. The main problem now is the middle of the operation process. How to do it is more energy-efficient. Currently, every ton of sewage is treated, the MBR technology is 0.1 kW higher than the traditional technology, and the clear water source is thinking of various energy-saving measures to improve efficiency. At the same time, he believes that there is no perfect technology, MBR can not be wrapped around the world. For example, in many sparsely populated places, the natural environment has self-cleaning function, so it is not necessary to use MBR, and traditional techniques are good. In this respect, foreign countries are not one-size-fits-all. If there is enough local pollution capacity, such as secondary processing, then there is no need to use MBR. It is also recognized by industry insiders that the high operating cost of MBR technology is mainly due to high power consumption, but he believes that MBR processing unit consumption is above 1 kWh.

Speaking of the advantages and disadvantages of MBR technology and other processes, Zhang Zhuai thinks that the activated sludge method has been used as an example. This method has been applied internationally for more than 100 years and is relatively more mature and has been adopted abroad; MBR technology is relatively small in foreign countries, and it is mostly smaller projects. MBR technology itself is a combination of biological method and membrane. The biological method itself has matured, and the problem of MBR technology is concentrated on the membrane. The durability and anti-pollution properties of membrane materials still have room for improvement. It is believed that after a period of time for the development of manufacturers, market testing, and experience accumulation, the prospects for the development of MBR technology will be even broader, indeed, the value of water reuse. On the other hand, MBR technology only has a greater significance in applications where the space is limited and where the quality of the effluent water is extremely high. This has also played its unique features. In addition, the MBR technology has not applied as large-scale and long-term as the traditional activated sludge method. In China, the 100,000-ton MBR sewage treatment plant is also the product of recent years. The industry has large-scale sewage treatment for MBR. The application experience of the plant is not enough, and the relevant technical risks also need to be evaluated in depth. At the same time, MBR investment will not be as large-scale as the traditional sewage treatment plant. To process more wastewater requires more membrane modules, the investment and the amount of water treatment is almost a linear relationship. Moreover, the high power consumption of MBR technology is one of the reasons why people still have doubts about it.
