035 | UV Water Systems Oman
The Toray TM720D-400 is a premium brackish water RO membrane manufactured by Toray Industries Japan — one of the world’s largest and most respected membrane manufacturers. Supplied in Oman by UV Water Systems Muscat, the TM720D-400 in 8040 format delivers 99.7% salt rejection (higher than the standard BW30-8040) with excellent stability across the wide temperature range experienced in Oman — from 15°C winter feed water to 40°C+ summer temperatures.
Why This Matters for Oman Water Quality
Some Oman industrial applications — pharmaceutical water for injection (WFI) pre-treatment, electronics rinse water, and power plant condensate polishing — require higher salt rejection than the standard 99.5% offered by the Filmtec BW30-8040. The Toray TM720D-400 at 99.7% rejection produces permeate TDS approximately 40% lower than the BW30-8040 from the same feed water — useful when post-RO demineralisation resin run lengths need to be maximised. UV Water Systems offers both Filmtec and Toray elements and will recommend the best fit for your specific application.

Frequently Asked Questions
Is the Toray TM720D-400 compatible with my existing 8040 membrane housing? Yes — the Toray TM720D-400 is manufactured in standard 8-inch diameter × 40-inch length format and fits all standard 8040 FRP and SS membrane pressure vessels. Interconnectors and O-rings are standard 8040 size. UV Water Systems can confirm compatibility with your specific vessel brand before supply.
Can I mix Toray and DuPont Filmtec membranes in the same vessel? In theory yes — but UV Water Systems recommends using matched elements from the same manufacturer and product line within a vessel array for consistent performance. If upgrading from Filmtec to Toray, replace the full vessel complement rather than mixing. Call +968 9763 7786 for a membrane upgrade consultation.
