INSTALLATION & USE
Installing the TMH10A Membrane
- Shut down the RO system completely and relieve all pressure from the membrane housing before opening
- Remove the old membrane if replacing, then slide the Toray TMH10A into the pressure vessel with the brine seal oriented correctly toward the feed end
- Install end caps, lubricate o-rings with clean silicone grease, and torque housing to manufacturer specifications
- Flush the new membrane at low pressure (25-30 psi) for 30-60 minutes before placing the system into full production
- Monitor TDS and flow rate during the first 24-48 hours of operation to confirm proper performance
COMPATIBILITY
System Requirements
The Toray TMH10A fits all standard 4-inch diameter by 40-inch length commercial RO membrane housings, including systems from Pentair, DOW, Hydranautics, and other manufacturers using the 4040 format. Designed specifically for brackish water sources with TDS levels between 2,000-10,000 ppm, this membrane performs best in systems with feed pressure between 150-225 psi. Verify your housing dimensions and feed water quality before ordering. Professional installation is recommended for commercial applications to ensure proper system startup and performance validation.
🔧 Pro tip: Always check and record your baseline rejection rate and permeate flow within the first week of operation. These numbers become your reference for monitoring membrane health over time and catching fouling or scaling issues before they impact water quality.
