Dairy processing is among the most water-intensive sectors of the food industry, generating large volumes of high-strength wastewater that demands effective treatment before discharge or reuse. Ceramic membrane ultra filtration (UF) has emerged as a leading technology for this purpose, offering superior chemical stability, long service life, and exceptional contaminant removal efficiency. This article reviews the characteristics of dairy wastewater, the principles and advantages of ceramic UF membranes, key performance data, fouling mechanisms, and prospects for integrated treatment systems.

Ceramic membranes have emerged as a critical technology in industrial separation and treatment processes, with the global market experiencing robust growth in 2025. The market is valued at approximately USD 8–12 billion in 2025 and is projected to expand significantly over the coming decade, driven by increasing demand for water treatment, wastewater management, and gas separation applications. These durable, long-lasting materials are becoming the preferred choice for industries seeking sustainable and efficient separation solutions.
