TW30HP-4611

Summary

Product identification

FilmTec™ 4.6-inch diameter reverse osmosis (RO) elements are designed to provide high-quality water for sanitary applications. They feature the high-performance TW30HP membrane, known for excellent permeate flow and salt rejection. These elements are constructed with the same high-quality materials as larger FilmTec™ Elements used in municipal and industrial systems. They are available in wet or dry form for shipping, storage, and loading convenience.

Important Operating Information

• Elements must be kept moist at all times after initial wetting.
• Failure to strictly follow operating specifications may void the FilmTec™ Reverse Osmosis and Nanofiltration Three-Year Prorated Limited Warranty.
• For biological growth prevention during storage, shipping, or shutdowns, elements should be immersed in a protective solution (e.g., 1.0% by weight sodium metabisulfite, food grade).
• Customers are responsible for the effects of incompatible chemicals on elements; their use will void the warranty.
• The use of this product does not guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
• Permeate obtained from the first hour of operation should be discarded.
