Hot Water UF System: Features, Benefits & Applications

A Hot water UF system is a highly specialized UF system that uses special thermally stable membrane modules to run at high temperatures (usually 60°C to 85°C).

Normal ultrafiltration systems will only break down or lose structure if subjected to high temperatures, but these systems are designed to handle continuous exposure to hot water temperatures or periodic hot water sanitizing cycles. The pores in the membrane are in the range of 0.01 to 0.1 micron, which create a definite physical barrier to remove macromolecules, colloidal silica, proteins, pyrogens, and endotoxins without using aggressive chemical dosing.

Thermal Stress Performance Features

A Hot water UF system uses very special materials and controls to perform at peak efficiency during thermal stresses:

• Heat-Resistant Membranes: Manufactured with state-of-the-art PVDF (Polyvinylidene Fluoride) or polysulfone hollow-fiber membranes which retain accurate pore structure during thermal expansion.
• Sanitary Hardware Skids: Incorporates fully welded and electro-polished SS 316L stainless steel piping with high quality Viton or EPDM gaskets for leak-free operation at high temperatures.
• Automated Thermal Controls: PLC controlled panels with digital temperature transmitters, allowing for a smooth ramp up and down of temperatures to avoid thermal shock to the system components.
