When water has high mineral content (above 3 GPG, or grains per gallon) it’s considered ‘hard’ water. These minerals can clog components, and harm the performance of processes, most notably RO filtration Water softening removes excess minerals, usually by exchanging calcium and magnesium (hardness) for sodium to remove the hardness.
VARIABLES TO CONSIDER:
- Water hardness level
- System size and flow rates
- Types of control heads
- Steel versus FRP tank,
- face-piping versus top mount valves.
- Boiler Feed
- RO system pretreatment
- Cooling towers
- Hospitals And Universities
- Food And Beverage
FREQUENTLY ASKED QUESTIONS (FAQ’s):
Do I need a water softener for RO system feed? Water hardness will clog RO membranes. You can treat with a softener. Or, as another option you can use a chemical antiscalant. Antiscalants can also be used for RO feed when sodium discharge from softener is an issue.
I’m getting hard water from softener, what is going on? Your system probably requires service. Problems may include salt bridging in brine tank, empty brine tank (no salt), a problem with safety float in tank, a gallon meter problem, or old softener resin.
