Experts Discuss How Low-Carbon Membrane Technology and New Materials Contribute to High-Quality Drinking Water Treatment

On May 10th, the National Water Science and Technology Conference and Technology Equipment Achievements Exhibition was held in Fuzhou. During the conference, Jiuwu Hi-Tech co-hosted the "Low-Carbon Membrane Method + New Materials Cross-Border Integration Forum in High-Quality Drinking Water Treatment" together with the Hangzhou Water Treatment Technology Research and Development Center, becoming a major highlight. Concurrently, the high-packing area ceramic membrane equipment for water treatment was selected as part of the "2025 Innovative Technologies and Products Cases for Water Environment Management."

Low-Carbon Membrane Forum: Discussing New Trends in Drinking Water Treatment

In the "Low-Carbon Membrane Method + New Materials Cross-Border Integration Forum in High-Quality Drinking Water Treatment," Wang Zongheng, a senior engineer at Jiuwu Hi-Tech's membrane water treatment department, elaborated on the research background, ceramic membrane application design, and shared classic cases.

Currently, membrane filtration technology has become one of the emerging advanced drinking water treatment technologies. The most common membrane treatment technology for drinking water treatment in China is ultrafiltration membrane treatment. Most ultrafiltration membranes used in water treatment are dominantly organic membranes. However, ceramic membranes, with their excellent performance, have started to be widely used in domestic water treatment plants.

As a leading enterprise in the ceramic membrane field within the membrane industry, Jiuwu Hi-Tech was the first to break the foreign monopoly, producing ceramic membrane products with independent intellectual property rights. Ceramic membranes, made from inorganic ceramic materials such as alumina, titanium oxide, and zirconia through high-temperature sintering, are precise filtering materials with a porous structure. They are composed of a porous support layer, a transition layer, and a membrane layer, arranged asymmetrically. The filtration precision covers microfiltration, ultrafiltration, and small pore sizes (≥2nm). These membranes have been widely used in the separation processes of pharmaceuticals, food, chemicals, and water treatment.

Application of Ceramic Membranes in Drinking Water Treatment

• Effectively removes particulate matter, bacteria, viruses, protozoa, and aquatic organisms from water, reducing the amount of disinfectant added and lowering the formation of disinfection by-products. The treated water turbidity is <0.05 NTU, ensuring water quality.

  
  

• Short-process techniques (direct ceramic membrane filtration, coagulation + ceramic membrane, coagulation-sedimentation + ceramic membrane).

  
  

• Through combined processes, comprehensively enhances the biological and chemical safety of drinking water (ozone + ceramic membrane, ozone + biological activated carbon + ceramic membrane).

Advantages of Ceramic Membranes in Drinking Water Treatment Processes

• High material safety: Ceramic materials are inorganic and chemically inert, resisting oxidation or degradation by strong oxidizers such as chlorine and ozone. They are not susceptible to microbial erosion and pose no risk of microplastics or PFAS materials.

  
  

• High assurance of water quality: Even with water quality fluctuations (rainy seasons, seasonal changes), treated water turbidity remains below 0.05 NTU.

  
  

• Good anti-pollution performance: The chemical inertness of ceramic materials prevents oxidation or degradation by strong oxidizers like chlorine and ozone. Its acid and alkali resistance allows various cleaning agents to be used for membrane cleaning. Both physical and chemical cleaning are highly efficient.

  
  

• Long lifespan: They can last up to 20 years, reducing replacement frequency and costs, minimizing the consumption of construction materials, and meeting green environmental protection requirements.

Participants in this forum included leaders and guests from Hainan Litree Water Purification Technology Industry Co., Ltd., Zhejiang Wiscent Fluid Equipment Co., Ltd., Austin Pumps (Zhejiang) Co., Ltd., Jiuchuan Smart Link Technology (Hangzhou) Co., Ltd., Zhejiang Easthope New Materials Technology Co., Ltd., Omnium New Materials (Zhejiang) Co., Ltd., Chongqing Water Group Co., Ltd., and others. These participants focused on high-quality drinking water and membrane technology, presenting advanced industry perspectives and innovative technologies.

Selected as an Outstanding Case: The Battle of Domestic Membranes from Laboratories to Water Plants

This conference, themed "Promoting Deep Integration of Water Industry Technology Innovation and Industrial Innovation," gathered industry experts, corporate representatives, and research institutions. It explored frontier technologies and development models in the water technology field through in-depth dialogues. The conference innovatively adopted a "1+7+N" multi-agenda system, incorporating main forum macro-strategy discussions, precise matchmaking of upstream and downstream industries, annual technological achievement releases, and parallel forums covering seven areas: rural water environment governance, AI water quality monitoring, smart water low-carbon management, zero industrial wastewater discharge, membrane technology iteration, sponge city construction, and reclaimed water reuse. This system comprehensively built a full-chain communication platform from policy orientation to technology implementation, injecting new impetus for the industry's transformation and upgrading.

At the conference, Jiuwu Hi-Tech also showcased its main products such as tubular ceramic membranes, silicon carbide ceramic membranes, and high-packing ceramic membranes. In the award ceremony, Jiuwu Hi-Tech's "high-packing area ceramic membrane equipment for water treatment" successfully made it into the "2025 Innovative Technologies and Products Cases for Water Environment Management." By optimizing membrane module packing density and flow path design, the equipment increases the membrane area per unit volume by more than 30%, significantly reducing energy consumption and operation costs. It has already achieved large-scale application in several major water plants nationwide, with a daily processing capacity exceeding one million tons.

This honor not only acknowledges the company's technological leadership but also highlights the benchmark value of domestic ceramic membranes in addressing drinking water safety and efficiency, providing a replicable innovation model for the high-quality development of the industry.
