Alumina
Optimize filtration across all Bayer Process steps with high-performance filter media. Reduce costs and ensures consistent quality of smelter (SGA) and chemical grade (CGA) alumina.
Filtration Solutions for Efficient and Sustainable Alumina Production
Boost Efficiency
Durable filter media reduces maintenance, extends service life, and lowers filtration cost across all Bayer Process steps.
Ensure Reliability
Engineered solutions ensure high clarity, stable throughput, and efficient dewatering under caustic and abrasive conditions.
Suitable Solutions for Every Step
Sefar provides tailored filtration solutions for all stages of alumina refining to enhance process stability, reduce costs, and ensure consistent output of SGA and CGA across the Bayer Process.
