Dairy10K

Product catalog summary

Introduction
Hydranautics specializes in membrane innovation, design, and manufacturing, offering the Dairy10K membrane elements known for high performance and value. These elements are produced under ISO 9001-compliant processes, ensuring quality and reliability. The membranes are constructed with a polypropylene-backing substrate for enhanced chemical resistance and longevity.

Specifications
The Dairy10K membranes are USDA-accepted, high-flux, 10,000 Dalton polyethersulfone ultrafiltration crossflow membrane elements. They are suitable for dairy, biopharmaceutical, beverage, and other applications. The membranes provide maximum protein rejection and chemical resistance, meeting FDA regulation CFR Title 21 and 3A Sanitary Standards.

Testing and Performance
Each membrane undergoes 100% testing with 500 ppm PEG 6000 for 97% rejection and flux standard adherence. Dry-vacuum testing ensures module integrity. Applications include whey concentration, enzyme and protein concentration, and pre-concentrating milk or whey to reduce transport costs.

Construction and Materials
The membranes are made of patented "dry" polyethersulfone for maximum oxidation resistance and blister-resistant glue-line adhesion. They do not use chemical preservatives, enhancing element life and storage ease.
