High-Performance Filtration for Demanding Applications

Ultrafiltration (UF) is a pressure-driven membrane separation process that removes suspended solids, bacteria, viruses, and other contaminants from water. With membrane pore sizes ranging from 0.01 to 0.1 microns, UF offers a tighter filtration threshold than microfiltration, making it ideal for demanding applications in industrial, municipal, and commercial water treatment.

Whether you’re concentrating proteins in a biotech application or pre-treating feed water for reverse osmosis, UF delivers reliable performance, consistent quality, and low operating costs.

Benefits of an ALSI Ultrafiltration System?

ALSI’s Ultrafiltration systems are designed with durability, efficiency, and operator ease in mind. From consistent output quality to reduced maintenance, every component is engineered to simplify your treatment process and deliver dependable results—day in and day out.

• Superior Protection for Downstream Equipment – UF acts as a physical barrier that helps reduce fouling in downstream processes such as Reverse Osmosis, increasing efficiency and equipment life.
• Reliable Removal of Suspended Solids – UF membranes efficiently reject particles, viruses, and polypeptides for consistently clear water quality.
• Stable Performance Across Varying Feed Water Conditions – Regardless of fluctuations in feed water, UF delivers predictable results with SDI values typically less than 2.
• Compact Footprint & Simplified Process – Replace multiple treatment steps with one compact UF system—lowering space requirements and system complexity.
• Reduced Chemical Usage and Waste – Fewer treatment chemicals mean less sludge and lower disposal costs, improving both environmental impact and operating expenses.
