The overall competitive pattern of the reverse osmosis membrane industry: domestic companies have a small market share

Currently companies in the reverse osmosis membrane market It mainly focuses on internationally renowned membrane manufacturers, and most of them are diversified large-scale enterprises, such as Dow Chemical of the United States, Hydraulics of the United States, Toray of Japan, etc.; the membrane business is only a business unit under its diversification strategy. It is worth noting that major companies are expanding their business areas into the water treatment or membrane manufacturing industry, and then acquiring existing companies and businesses to gain market share and complete category technologies.

At present, 90% of China's reverse osmosis membrane market is imported membranes. Among them, the membrane products of the American Hydranautics/Nitto Denko and the American Dow Chemical Company (Dow Chemical/Filmtec) account for approximately 70% of the market share, the rest of the foreign film manufacturers, such as the United States Koch/Fluid System, Osmonics/Desal, South Korea's csm/Saehan (csm/Saehan), Japan's Toray and other companies account for about 15% of the market. Domestic films only account for about 10% of the market.

The application of membrane technology in my country started late, but since 2000, there have been many industry participants, but most of them focus on the production of ultrafiltration membranes. At present, the well-known domestic reverse osmosis membrane manufacturers include Guizhou Times Wharton Technology Co., Ltd., Beijing Bishuiyuan Membrane Technology Co., Ltd., Tangshan Haiqingyuan Technology Co., Ltd., Tianjin Mangtian Membrane Technology (ultrafiltration membrane), Blue Star Dongli Membrane Technology Co., Ltd., Hangzhou Yimo Environmental Protection Technology, Hunan Qinsen Environmental Protection High-Tech Co., Ltd., Hangzhou Water Treatment Technology Research and Development Center and Shandong Jiuzhang Membrane Technology Co., Ltd., etc.

Compared with well-known foreign-funded enterprises, most domestic reverse osmosis membrane manufacturers are small in scale, weak in technical strength, and product quality is not stable enough. But the advantage lies in the low price, the support of downstream water treatment and environmental protection engineering enterprises, the complete industrial chain, and the support of the huge domestic domestic demand market. At present, the localization rate of domestic household reverse osmosis membranes is high, but the domestic production rate of industrial reverse osmosis membranes needs to be improved.

Segmented industry - seawater desalination reverse osmosis membrane Domestic enterprises are in the stage of technological breakthroughs and competition is gradually strengthening

Seawater desalination has made great progress in recent years, and related equipment and investment scales have continued to grow. According to incomplete statistics, by the end of 2019, there were 115 seawater desalination projects nationwide, with a project scale of nearly 160 tons/day. At the same time, the standard system for seawater utilization has been gradually improved, and major breakthroughs have been made in large-scale international seawater desalination projects undertaken by domestic enterprises. In particular, a number of representative enterprises have emerged in key technical fields.

With the localization of core equipment and key technologies, the system integration and engineering construction capabilities of the seawater desalination industry have continued to make breakthroughs and have now entered a very critical stage.

1. Seawater Desalination Equipment Industry

From the perspective of market segments, key enterprises in my country's seawater desalination equipment industry include Zhejiang Hailiang Co., Ltd. and Shuangliang Energy Saving System Co., Ltd. Company, Dow Chemical (China) Investment Co., Ltd., Southern CICC Environmental Co., Ltd., Zhejiang Jiulite Material Technology Co., Ltd., Tianjin Mantian Membrane Technology Co., Ltd., Blue Star Dongli Membrane Technology Co., Ltd., etc.

Except for Dow Chemical (China) Investment Co., Ltd. and Blue Star Toli Membrane Technology (Beijing) Co., Ltd., which are unlisted companies, the other companies are all listed companies.

It can be seen that competition in my country's seawater desalination equipment industry is gradually intensifying, and the overall operating strength of enterprises is increasing.

The gross profit margin can reflect the profitability of the company, and the asset-liability ratio can reflect the scale of the company's debt. Analysis of these two factors can help investors make judgments.

In terms of gross profit margin, among the listed companies among the representatives of China’s key seawater desalination equipment production enterprises, the gross profit margin of CICC Environment has been at a relatively high level from 2015 to the first quarter of 2021. The overall changes are in line with the gross profit margin. The average interest rate changes have converged; Hailiang Shares has been at a level of around 5%, and the gross profit margin level is relatively low among representative companies. Among these representative companies, the average gross profit margin fluctuates around the level of around 25%.

2. Competition among seawater desalination engineering enterprises

There are relatively few seawater desalination engineering enterprises in my country. Currently, the enterprises with good development include: Shanghai Baan Water Co., Ltd., Lightleder (Beijing) ) Environmental Technology Co., Ltd., Shandong Haihua Co., Ltd., Southern Huitong Co., Ltd., China International Shipping Containers (Group) Co., Ltd., Beijing Bishuiyuan Technology Co., Ltd., etc.

In terms of gross profit margin, among representative companies in China's seawater desalination engineering industry, Southern Huitong's gross profit margin fluctuated around 38% from 2015 to the first quarter of 2021, which is at a relatively high level among representative companies; Shandong Haihua and CIMC Group have been below the average, fluctuating around 15%. The average gross profit margin among representative enterprises in China's seawater desalination engineering industry has not changed much over time, fluctuating around the 27% level.

Segmented industries - high-salt wastewater treatment reverse osmosis membrane environmental protection policy drives enterprise development

my country's high-salt wastewater treatment market is mostly industrial high-salt discharged by enterprises in the chemical industry. salt wastewater for disposal. However, in recent years, as my country continues to strengthen the implementation of environmental protection policies, some excellent high-salt wastewater equipment manufacturers have emerged, such as Beijing Jialin Biotechnology Co., Ltd., Henan Yuhan Environmental Management Co., Ltd., and China National Offshore Oil Corporation , Henan Yuhan Environmental Management Co., Ltd. and Beijing Zhongke Guoyi Environmental Protection Engineering Co., Ltd., etc.

In June 2016, the Ministry of Industry and Information Technology issued the "Industrial Green Development Plan (2016-2020)", proposing that by 2020, a green manufacturing system will be initially established. Under the national policy of developing high-tech industries and developing "green industries", my country's high-salt wastewater treatment enterprises will receive further support and development.

With the continuous expansion of the scale of industrial water treatment and the continuous improvement of water treatment requirements, the demand for industrial separation membranes has further shifted to high-end. At present, the high-end market of industrial membranes is dominated by well-known foreign brands. The localization rate is low and is still in the process of localization.

Eugene De, Secretary-General of the Asia-Pacific Desalination Association, believes that the membrane industry is a technology-driven industry and is still in the growth stage. In order to ensure the long-term stable and healthy development of the industry, it is necessary to continuously promote technological upgrades, improve and optimize products. structure to expand application areas.
