Questions
Asked before we start work.
FRP or stainless — how do you choose?
- RO membrane housings are typically FRP at the required pressure class. Cartridge and specialty duties may be stainless. Connections and code needs decide the rest.
Can new vessels take our current membranes?
- We specify internal diameter, length and port style to match the elements you already run — or the elements you plan to load.
