Frequently asked questions
Reverse Osmosis questions
How do you select the right system?
We start with the water source, testing, available flow and the amount and quality of treated water required.
Is testing always required?
The scope depends on the source and concern. Field measurements may be sufficient for some decisions; other conditions benefit from laboratory analysis.
How is ongoing service planned?
Filter, media and membrane service intervals depend on feed-water conditions, usage and the equipment selected.
