Highlights Preview: Jiuwu Hi-Tech Shines at Hangzhou Water Association Annual Conference

From April 17 to 20, the "China Urban Water Association 2025 Annual Conference with Urban Water Technology and Products Exhibition" (referred to as the "Water Association") will open at the Hangzhou International Expo Center. As an annual industry event in the urban water field, this conference will carry out in-depth discussions around industry policies, development trends, and other hot topics, jointly exploring paths for high-quality development in the water industry.

At this year's annual meeting, Jiuwu Hi-tech, a leading enterprise in the domestic ceramic membrane industry, will make a grand appearance with core technologies and innovative achievements (Booth No.: 3B-408). The company will focus on showcasing its full-chain membrane technology solutions in water supply-wastewater-drainage, as well as independently developed ceramic membrane series products, presenting the company's innovative application achievements in the field of municipal water purification.

Ceramic Membrane Applications and Cases

The third-generation drinking water purification process centered around Jiuwu Hi-tech's ceramic membranes can effectively solve the safety and hygiene issues of domestic drinking water, producing high-quality water that meets and, in some respects, exceeds the requirements of the national "Standards for Drinking Water Quality" (GB5749-2022). It is suitable for new urban water plants, upgrading old water plants, and rural drinking water.

Advantages of Ceramic Membranes in Water Plants

Superior Water Quality

Firstly, the removal rate of particulate matter, bacteria, viruses, algae, two parasites (including Giardia and Cryptosporidium), and protozoa in the water exceeds 99.9%.

Secondly, the ceramic membrane water plant process can effectively reduce the addition of disinfectants, thereby reducing the generation of disinfection by-products. 

Thirdly, the effluent turbidity is consistently ≤0.1 NTU, whereas the effluent turbidity of conventional process water plants is generally ≤0.5 NTU.

Land Saving

Firstly, compared to conventional processes and organic membranes, it has higher water purification efficiency. 

Secondly, it uses a short process that saves space.

Long Service Life

With good durability, the usage life can last up to 20 years, reducing the frequency and cost of replacements, minimizing construction material consumption, and meeting green environmental protection requirements.

High Material Safety

Ceramic materials are inorganic and chemically inert, not subject to oxidation or degradation by strong oxidants like chlorine and ozone, nor subject to microbial erosion, and there is no risk of microplastics or PFAS materials.

Leading Enterprises Promote the Development of High-Quality Drinking Water

Jiuwu Hi-tech is recognized in the industry as the "Pioneer of Chinese Ceramic Membrane Technology." After nearly thirty years of innovative development, Jiuwu Hi-tech, centered around independently developed ceramic membranes and organic membranes, focuses on providing efficient separation and resource solutions in urban water supply, wastewater treatment, and industrial water recycling. It has participated in drafting over 10 national/industry standards and covers the entire water treatment process, serving over 1,000 municipal and industrial projects across the country. At this year's annual conference, Jiuwu Hi-tech will showcase its three main membrane products: ceramic membranes, high-packing column type ceramic membranes, and organic membranes.

Advantages of Ceramic Membranes

Ceramic membranes are precision filtration materials made from inorganic ceramic materials such as alumina, titania, and zirconia, sintered at high temperatures to form a porous structure. They consist of a porous support layer, a transition layer, and a membrane layer with asymmetric distribution, covering microfiltration, ultrafiltration, and nanofiltration accuracies.

Advantages of High-Packing Column Type Ceramic Membranes

The high-packing column type ceramic membrane is a new type of inorganic ultrafiltration membrane developed based on tubular ceramic membrane and flat-sheet ceramic membrane technologies. It often adopts the "micro-cross-flow filtration" form, featuring high packing density, large filtration area, and stable operation flux. The effective filtration area of a single membrane module is 10㎡~30㎡, capable of effectively removing solids, bacteria, and colloids, and can be widely applied in municipal tap water, municipal wastewater, mine water, emergency water supply, wastewater reuse, and salt lake lithium extraction, among other fields.

Advantages of Organic Membranes

After years of research and development, Jiuwu Hi-tech built three major workshops with five production lines in 2019, including roll production lines, hollow fiber column-type membrane production lines, hollow fiber curtain-type membrane production lines, non-woven tubular membrane production lines, and sintered tubular membrane production lines.

During this year's Water Association Annual Conference, Jiuwu Hi-tech, with its futuristic breakthroughs in ceramic membrane technology and full industry chain solutions, will provide strong support for the improvement of quality and efficiency, resource recycling, and low-carbon development of urban water services, showcasing the core value and broad prospects of membrane technology in the water treatment field, helping China's water industry to embark on a higher quality and more sustainable new journey.
