Good News: The dual-outlet MBR flat membrane module of Peier Membrane Industry has been selected for

The moment of glory is well-deserved

Recently, the Ministry of Water Resources of the People's Republic of China officially released the "List of Advanced and Mature Water-saving Technologies and Equipment (2025)". The dual-outlet MBR flat membrane module technology and equipment independently developed by Jiangsu Peier Membrane Industry Co., Ltd. (stock code: 836744) was successfully included. This inclusion, as an authoritative certification at the national level, fully demonstrates the outstanding advantages of this technology and equipment in water-saving performance and application maturity, marking that Peier Membrane Industry's technological strength in water-saving and water treatment has been recognized by the national authority and placed it among the leading ranks of the industry.

Glory moment, authoritative certification

The selection of the "List of Advanced, Mature and Applicable Water-Saving Technologies and Equipment (2025)" underwent multiple rounds of rigorous reviews including self-recommendation and expert evaluation. The final included technologies and equipment have all been verified through practical applications and possess significant water-saving benefits as well as wide promotion value. They hold important practical significance and long-term value in guiding the industry to transform from "passive water-saving" to "active efficiency creation", promoting efficient utilization of water resources, and achieving the "dual carbon" goals.

This technical equipment can stand out among numerous candidate products, and its core lies in the profound technical research and development accumulation of Peier Membrane Industry and the core technical advantages of its products. As an upgraded and iterative product of the membrane bioreactor (MBR) technology, this component is based on a patented technology of a dual-outlet flat membrane module independently developed by Peier Membrane Industry. It uses a flat membrane made of PVDF (polyvinylidene fluoride) and PET (non-woven fabric) as the material. The innovative design of this component is that there are two water outlet holes on both the top and bottom sides of the membrane element. During the membrane filtration process, this dual-outlet design, combined with the external suction system, can make the negative pressure distribution on both sides of the membrane sheet more balanced, effectively reducing the filtering dead zone and local accumulation of membrane contaminants, thereby improving the membrane flux. The membrane module adopts a top-insertion and removal type installation frame. During maintenance and repair, any single membrane element can be removed separately for cleaning or replacement without emptying the entire membrane pool, which greatly simplifies the maintenance work and improves the online maintenance performance and operational stability of the system.

In terms of separation efficiency, the innovative dual outlet design optimizes the flow dynamics, and combined with a 0.1μm pore size membrane material, it significantly enhances the membrane flux and water product uniformity. After treatment, the turbidity of the effluent is ≤ 1 NTU and the suspended solids are ≤ 5mg/L. The water quality is superior to the national first-level A standard, and it can be directly used as non-potable water for reuse, achieving efficient conversion of wastewater resourceization.

In terms of operating costs, it not only has excellent anti-pollution performance, effectively reducing the adhesion of contaminants on the membrane surface, prolonging the cleaning cycle, but also increases the service life to the industry-leading level, significantly reducing the costs of equipment replacement and operation, and helping customers achieve the dual goals of cost reduction and efficiency improvement.

In terms of application scenarios, this component has extremely strong adaptability to various situations and can be widely applied in multiple fields such as municipal sewage treatment, village and town sewage purification, and industrial wastewater reuse.

Begun in concept, achieved through practice

This selection is not only an authoritative endorsement of Peier Membrane Industry's technological innovation capabilities, but also a full affirmation of the company's commitment to the green development concept. Over the years, Peier Membrane Industry has been deeply engaged in the field of membrane separation technology, always taking "producing good products, selling good products, and enabling customers to use good products" as its core mission. It focuses on the key technological shortcomings in industrial water conservation and industry demands, and continuously promotes technological research and development andachievement transformation. Relying on core technologies such as dual outlet MBR flat membrane modules, the company has built multiple water-saving demonstration projects nationwide, promoting the value transformation of "wastewater into resources", and providing replicable and scalable technical paths for water-saving renovations in industries such as chemical and pharmaceuticals, animal husbandry, hospital wastewater, municipal parks, washing wastewater, and highway wastewater.

The recognition of the national list is not only an honor but also a responsibility. In the future, Peier Membrane Industry will take this as an opportunity to further deepen membrane technology research and innovation, continuously optimize the performance and application solutions of dual outlet MBR flat membrane components, increase the intensity of technology promotion, and enable advanced water-saving technologies to benefit more industries and regions. At the same time, the enterprise will actively respond to the national water-saving policy call, fully exert its leading role as a benchmark, and work together with industry partners to promote the iterative upgrade of water-saving technology equipment, helping to build a green ecosystem of "water-saving - pollution reduction - carbon reduction" that develops in a coordinated manner. It will contribute more Peier strength to the construction of a water-saving society and the efficient utilization of water resources!
