DOW Filmtec SW30-400 RO Membrane

DOW Filmtec SW30-400 RO Membrane is suitable for customers in the UAE who need better control over high TDS, taste variation, and mineral load that are common in UAE source water and tanker-supplied water. Aqua Best assesses feed-water readings, daily consumption, and installation requirements so the final system is sized for local conditions rather than copied from a generic product page.

For residential and commercial use in the UAE, the goal is to reduce dissolved solids, improve drinking-water consistency, and protect downstream components from unnecessary scaling stress. We help match membrane capacity, pretreatment stages, storage volume, and maintenance planning to the actual water profile, usage pattern, and service expectations of the site.

DOW Filmtec SW30-400 RO membrane is designed for seawater desalination, providing a production capacity of up to 8,500 gallons per day. It offers a 99.7% nominal salt rejection rate, ensuring high-quality water. Its robust design supports high-pressure operations, making it suitable for large-scale industrial applications.

TDS Explanation

TDS (Total Dissolved Solids) indicates the amount of dissolved minerals and salts present in water. The right filtration setup helps reduce excess TDS and improve taste, odor, and overall water quality based on source-water conditions.

Installation

Our team provides on-site installation, pressure and leak checks, flushing, and final performance testing. Proper installation ensures stable flow, safe operation, and long service life of the filtration system.

FAQ

How often should filters be replaced? Replacement intervals depend on usage and feed-water quality; periodic service checks are recommended.

Do you provide maintenance support? Yes, we offer maintenance and service support plans for residential and commercial installations.
