Jiuwu + Municipal Water | Membrane Solutions for Safer Water

With stricter drinking water standards and increasing concerns over emerging contaminants such as microplastics and algae-related odours, traditional water treatment processes are facing new challenges. As a pioneer and leading company in ceramic membrane technology in China, Jiuwu Hi-Tech provides effective solutions for municipal drinking water safety through its independently developed high-packing-density ceramic membrane technology and other advanced membrane solutions. This not only supports the improvement of water quality standards but also reflects Jiuwu Hi-Tech's commitment to its mission of "Making industries more efficient and making life healthier."

Why Choose Ceramic Membrane Technology for Municipal Drinking Water Treatment?

Currently, many water treatment plants still rely on conventional treatment processes. However, with stricter drinking water standards and increasing requirements for controlling emerging contaminants such as antibiotics, endocrine-disrupting compounds, and microplastics, traditional processes face limitations in ensuring water safety.

Jiuwu Hi-Tech's high-packing-density ceramic membrane represents an advanced solution for deep water treatment. With pore sizes ranging from 0.003 to 0.01 μm, it can effectively remove suspended solids, bacteria, viruses, and microplastics from water, achieving up to 99.99% microorganism removal efficiency.

In addition, ceramic membranes are made of inorganic materials with excellent chemical stability. They can withstand strong oxidants such as chlorine and ozone without degradation, providing a reliable barrier for safer and cleaner drinking water.

What Are the Advantages of Ceramic Membranes in Treating Complex Water Sources?

Under certain climatic conditions, excessive algae growth in water sources can not only increase turbidity but also cause unpleasant tastes and odours in drinking water due to the release of metabolic by-products. Conventional treatment processes typically achieve only 70–80% removal of small algae, and the decomposition of dead algae under anaerobic conditions may generate sulphur-containing compounds.

With its high filtration precision, Jiuwu Hi-Tech's ceramic membrane technology can effectively handle high-algae water sources and maintain treated water turbidity below 0.05 NTU. In the Zhoushan Qushan Island project, the turbidity of treated water was further reduced to 0.018 NTU, significantly exceeding national standards.

In addition, ceramic membranes can be integrated with ozone and biological activated carbon processes to efficiently remove algal toxins and disinfection by-product precursors, further improving the chemical and biological safety of drinking water.

How Does High-Packing-Density Ceramic Membrane Technology Help Water Plants Reduce Costs and Improve Efficiency?

When expanding or upgrading municipal water treatment plants, limited space and high operation and maintenance costs are often major challenges. Jiuwu Hi-Tech's innovative high-packing-density column ceramic membrane adopts a modular design, increasing membrane area per unit volume by 50% and reducing the required footprint of water plants by approximately 40%. This provides an efficient and compact solution for the upgrade of existing water treatment facilities.

In terms of operating costs, ceramic membranes offer excellent fouling resistance, strong acid and alkali resistance, and easy cleaning and recovery performance. More importantly, their service life can reach up to 20 years, significantly reducing replacement frequency and long-term maintenance costs, while supporting more sustainable and low-carbon water treatment operations.

How Do Ceramic Membrane Stainless Steel Modules Solve the Cost Challenges of Rural Drinking Water Operations?

For rural water plants, high long-term operation costs and frequent replacement of consumables are major challenges. Jiuwu Hi-Tech's ceramic membrane stainless steel modules provide an effective solution to overcome these cost challenges.

Long service life and repeated use:

Unlike conventional filter cartridges that require frequent replacement, ceramic membrane elements can be repeatedly cleaned, regenerated, and reused. With a theoretical service life of up to 20 years, they significantly reduce consumable costs throughout the operation period.

Simple operation and reliable performance:

With a compact structure, easy installation, and stable operation, the modules simplify maintenance procedures and improve the efficiency of rural water plant management.

By combining efficient filtration performance, safe operation, and cost-effective design, Jiuwu Hi-Tech's ceramic membrane solutions provide long-term and reliable drinking water protection for applications such as centralized rural water supply and household water purification upgrades. They help reduce operating costs while ensuring safe and stable access to high-quality drinking water for communities.

What Are Jiuwu Hi-Tech's Successful Applications in Municipal Drinking Water Treatment?

Since the successful application of China’s first ceramic membrane drinking water project in 2012, Jiuwu Hi-Tech has developed a number of benchmark projects in the municipal water treatment sector.

In the 6,000 m³/d Qushan Island Water Plant upgrading project in Zhoushan, Zhejiang Province, Jiuwu's high-packing-density ceramic membrane technology achieved excellent performance, with treated water turbidity reaching as low as 0.02 NTU. In a township water plant project in Xuyi, Jiangsu Province, the short-process treatment system combining flocculation and sedimentation with ceramic membrane technology reduced the construction period by 40% and lowered energy consumption per tonne of water by 25%, providing a practical and replicable solution for rural water supply upgrades.

From large urban water plants to township water supply projects, Jiuwu Hi-Tech continues to improve drinking water quality through advanced membrane technology, ensuring safer and more reliable water supplies for communities.

From breaking the reliance on overseas ceramic membrane technologies to advancing next-generation drinking water treatment solutions, Jiuwu Hi-Tech has spent nearly three decades developing and applying ceramic membrane technologies in real-world applications. Whether for upgrading large municipal water plants or improving rural water supply systems, Jiuwu Hi-Tech delivers proven solutions and reliable technology to enhance drinking water safety.

Looking ahead, Jiuwu Hi-Tech will continue applying membrane technology to support better water management and contribute to healthier and higher-quality living through safer drinking water.
