Project Overview This ceramic membrane system was custom-developed specifically for a reclaimed water reuse project at a pharmaceutical enterprise. Utilizing inorganic ceramic membrane cross-flow filtration as the core process, the system integrates ceramic membrane modules, a circulation pressurization system, and an integrated piping skid. It is equipped with automatic backwashing, online chemical cleaning (CIP), and a PLC intelligent automation module. The designed treatment capacity is 800 tons/day. The equipment operates stably with consistently compliant effluent quality. The treated reclaimed water can be reused for production condenser makeup water and on-site landscaping irrigation, achieving resource recycling of pharmaceutical wastewater.

Process Features
1. Stable and Superior Effluent Quality for Direct Reuse The ceramic membrane features nanometer-scale precision pores that accurately retain suspended solids, colloids, bacteria, and macromolecular organics. The effluent is clear and stable, directly meeting stringent standards for landscaping, flushing, and production reuse. Compared to conventional processes, water quality is more controllable with minimal fluctuation, ensuring the reclaimed water is truly “usable and reliable.”
2. Exceptional Durability with Lifespan Far Exceeding Organic Membranes Resistant to high temperatures, acids, alkalis, oxidation, and abrasion, the ceramic membrane possesses high mechanical strength and is not prone to fiber breakage or damage. It maintains stable operation even under harsh water quality conditions. With a service life of 5–10 years—3 to 5 times longer than organic membranes—it significantly reduces replacement frequency and downtime losses, offering superior long-term cost-effectiveness.
3. Fouling Resistance and Easy Cleaning for Hassle-Free O&M The smooth, highly hydrophilic membrane surface prevents pollutant adhesion, resulting in low fouling rates and extended cleaning cycles. Supporting air scouring, backwashing, and chemical cleaning, flux recovery is rapid. Maintenance workload is reduced by up to 75%, while both chemical consumption and energy usage decrease, significantly lowering operational costs.
4. Compact Footprint and Simplified Process for Versatile Applications With high packing density of membrane modules, the footprint is reduced by approximately two-thirds, making it easy to deploy in both retrofit projects and new constructions. Featuring a high degree of automation and low sludge production, the system is adaptable to various reclaimed water reuse scenarios, including chemical plants, industrial parks, hospitals, hotels, and municipal facilities.
5. Low-Carbon and Cost-Effective Across the Full Lifecycle Combining long lifespan, low maintenance, and high energy efficiency, the total lifecycle cost is reduced by over 50%. Simultaneously, it minimizes consumable usage and carbon emissions, serving as both a powerful tool for water conservation and a benchmark choice for green, low-carbon development.
Conclusion Choosing ceramic membranes for reclaimed water reuse delivers stable water quality, extended lifespan, fouling resistance, compact footprint, and reduced costs. It achieves multiple objectives in one step: pollution control, water conservation, cost reduction, and low-carbon operation, making it a reliable solution for sustainable water resource recycling.
