Product Details
The residential ULP RO membrane uses a low‑energy polyamide composite layer that achieves stable rejection while keeping the pump workload low. Dry‑type construction means no preservative liquids – no mess, no sticky residue.
Key engineering features:
- Spiral-wound geometry – maximizes active area within a compact 1812/2012 housing.
- Wide operating pH range (3–10) – tolerates variations in tap water and well water.
- High fouling resistance – composite material lowers scaling and biofilm buildup.

FAQ
1. What is a residential RO membrane element?
A residential RO membrane element is an ultra low pressure reverse osmosis membrane designed for household and small-scale water purification systems. It operates at lower pressure while maintaining effective salt rejection and stable water output.
2. What are the differences between 1812 and 2012 RO membranes?
The main difference is size and water production capacity. The 2012 membrane has a larger surface area, providing higher permeate flow compared to the 1812 model, while both maintain similar filtration performance.
3. What type of feed water is suitable for this RO membrane?
It is suitable for municipal water and low salinity water sources. It can also handle feed water containing certain oxidizing substances and higher microbial content.
4. Can I use this membrane with a non‑pressurized storage tank or direct‑flow (tankless) RO system?
Yes, it works with both tank and tankless systems. For tankless systems that operate at intermittent high flow, we recommend the 75 GPD or higher model to keep up with demand. The membrane's low pressure requirement (65 psi) is compatible with most tankless RO booster pumps.
