Addressing the challenge of tap water odor, Jiuwu Hi-Tech Ceramic Membrane Technology ensures the safety of drinking water - 翻译中...

Current drinking water treatment technology has many drawbacks. To meet people's demand for healthy water and high-quality drinking water, Jiuwu Hi-Tech has launched mature and reliable solutions. Its ceramic membrane technology has been successfully applied in many drinking water projects like Zhoushan, Zhejiang etc., China, providing strong support for ensuring the safety and quality of drinking water.

The root cause of large-scale algae growth is eutrophication of source water. Algae concentrations can reach 10⁶-10⁷ cells per liter, or even exceed 10⁸. Water plants using the conventional coagulation-sedimentation-filtration-disinfection process typically achieve algae removal rates of 70%-80%. Smaller algae particles can even pass through sand filters. The presence of large amounts of algae not only creates water quality issues but also creates operational difficulties for water plants using conventional processes.

Algae are a significant contributor to unpleasant odors, flavors, and color. For example, blue-green algae produce geosmin and dimethylisoborneol. Furthermore, algae and their metabolites are important precursors of disinfection byproducts (DBPs) in drinking water, which can easily cause excessive disinfection by-products in drinking water and affect drinking water safety.

Even if the algae are killed by adding oxidants such as potassium permanganate and chlorine dioxide, on the one hand, the dead algae will release intracellular toxins that affect the safety of drinking water. On the other hand, the dead algae can degrade in an anaerobic environment and release sulfide substances such as dimethyl sulfide, causing unpleasant odors and tastes in drinking water.

About Jiuwu's Practice in Municipal Water

Faced with the need to ensure municipal drinking water safety, especially in addressing pain points such as algae blooms and odor removal, Jiuwu Hi-Tech, with its advanced ceramic membrane technology, has demonstrated mature and reliable solutions and significant results in domestic drinking water deep treatment projects.

Ceramic membranes have high filtration accuracy and can retain more than 99.99% of algae and bacteria in water. Even in the face of large-scale algae reproduction, the turbidity of the effluent can still be maintained below 0.05NTU, ensuring the safety of drinking water.

In addition, ceramic membranes can form a combination process with ozone or ozone + biologically activated carbon, which has a good removal effect on metabolites produced by algae and algal toxins released after the death of algae, comprehensively improving the biological and chemical safety of drinking water.

Advantages of using ceramic membranes in water plant processes:

High material safety: Ceramic materials are inorganic and chemically inert. It will not be oxidized or degraded by strong oxidants such as chlorine and ozone, and will not be eroded by microorganisms. It poses no risk compared to microplastics or PFAS materials.

High guarantee rate of effluent quality: In response to fluctuations in water quality caused by seasons and rainy seasons, the turbidity of produced water is stabilized below 0.05NTU, ensuring the stability of water quality. The ceramic membrane has a high water utilization rate, which can reduce the self use water rate of the water plant, reduce the wastewater discharge of the water plant, and improve the utilization rate of water resources.

Good anti-pollution performance: The ceramic membrane has a narrow pore size distribution, high tolerance to pollutants, resistance to acids, alkalis and oxidants, and high recovery efficiency after maintenance with physical and chemical agents.

Long service life: The service life can be up to 20 years, which reduces the replacement frequency and cost, reduces the consumption of construction materials, and meets the requirements of green environmental protection.

Jiuwu Hi-Tech's high packing density ceramic membrane can effectively cope with complex water source conditions such as high algae and high organic matter, providing cities with safer, more reliable and high-quality drinking water. It is one of the key technologies to improve the treatment efficiency of municipal drinking water plants and resist water source risks.

In the future, Jiuwu Hi-Tech will continue to deepen technological innovation, safeguard drinking water safety in more cities, and jointly build a solid foundation for people's well-being. Protect the source of life with technological "membranes."
