Towards the Sea, Strive for Strength Ⅲ

This is the third part of the series 'Towards the Sea, Strive for Strength' - the Project Section.

Under clear strategic guidance and solid technological support, BOW has steadily advanced its desalination layout, taking lead in domestic and international desalination projects and the localization of membrane technology.

1. Focus on Domestic Development: Create A National Benchmark

BOW has successively completed two large-scale seawater desalination projects in Shandong Province, each with a capacity of 100,000 t/d—Qingdao Dongjiakou Seawater Desalination Project (100,000 t/d) and the Shandong Lubei Seawater Desalination Project (150,000 t/d). Among them, Dongjiakou project employs BOW's independently developed dual-membrane process, making it China's first large-scale seawater desalination project to achieve full domestication of key technologies and equipment, successfully breaking foreign technological monopolies. It has been listed by the National Development and Reform Commission as a 'Reverse Osmosis Membrane Material R&D, Industrialization, and Demonstration Project.'

Lubei project also adopted dual-membrane process, continuously increasing the proportion of domestically produced equipment, reducing the water treatment cost per ton by about 30%, and achieving energy consumption indicators at international advanced levels, has made it one of the 14 key seawater desalination bases in Shandong Province.

Moreover, BOW participated in the construction of the Seawater Comprehensive Utilization Integrated Project in Huanghua (scale of 50,000 t/d), not only adopts dual-membrane technology but also integrates photovoltaic and energy storage systems to achieve 'green electricity for green water', aiming to create a new brand for the development of seawater desalination industry in Hebei Province.

2. Venturing into the World: China's Seawater Desalination Technology Sets Sail

Expanding into overseas markets is the inevitable path for Chinese enterprises to achieve leapfrog development. As a world-class water and membrane technology company, BOW has positioned seawater desalination as a key component of its global strategy.

In Gwadar, Pakistan, BOW has undertaken a seawater desalination plant project using 'UF + RO' dual-membrane process, with a daily water supply capacity of approximately 5,000 tons. This marks a significant leap from being a domestic leader to expanding overseas, laying a solid foundation for its internationalization strategy.

For the freshwater needs of hotel resorts, islands, and remote coastal areas, BOW has independently developed containerized integrated seawater desalination equipment. This equipment is compact, intelligent, energy-efficient, easy to deploy, and has been applied in multiple countries overseas. For example, in the palm oil industrial park of Sabah State, Malaysia, two specifications of seawater desalination equipment, 500 t/d and 2000 t/d, have been successfully implemented, setting a benchmark for further expansion into the Southeast Asian market.

3. Self Breakthrough: Achieving Replacement of Seawater Desalination Membranes

In addition to undertaking large-scale projects, BOW actively promotes the domestic substitution of RO membranes and dual-membrane technology, aiding China's seawater desalination industry to achieve self-reliance and control.

The Liuheng Island Seawater Desalination Project in Zhoushan, Zhejiang Province (with a capacity of 100,000 t/d) is the largest project in China that uses desalinated water as municipal water supply, and it has been jointly recognized as a scientific demonstration project by the Ministry of Science and Technology and the National Development and Reform Commission. In 2022, this project first adopted BOW's high-performance RO membranes, breaking the long-term dependence on imports and significantly reducing water production costs. Actual operation shows that BOW's RO membranes match imported products in terms of performance and stability, and have been continuously adopted for three years, setting a good example for controlling water supply energy costs in coastal areas of China.

BOW has also participated in the domestication and application of membrane elements for several seawater desalination projects, including Tangshan Sanyou Lanhai (2.5 million t/d), Qingdao Baifa Phase II (1 million t/d), Tianjin Dagang (1 million t/d), continuously promoting full-chain independent innovation in the industry.

With practical efforts as the boat and innovation as the paddle, BOW steadily advances in the era's wave of 'seeking strength from the sea.' Through the implementation of a series of major seawater desalination projects both domestically and internationally, and continuous breakthroughs in membrane technology domestication, BOW not only demonstrates the responsibility and commitment of the 'national team of membrane technology,' but also contributes solid strength to the high-quality development of China's marine economy. In the future, BOW will continue to deepen the layout of the blue economy, allowing more 'Chinese technology' and 'Chinese solutions' to benefit the world.
