Antiscalant for RO membranes: when does it really protect the membrane?
Antiscalant is a treatment product to prevent salt precipitation on reverse osmosis membranes. It protects membranes from scale and prolongs their lifespan.
How does the anti-scalant work?
Antiscalant maintains hardness salts in solution, preventing their crystallization on the membrane surface and decreasing performance of RO station.
Why are chlorine and chlorides dangerous to membranes?
They degrade the membrane structure. Therefore, it is important to control them, our treatment product can bind these gases.
FAQ
Frequently Asked Questions
Short answers to questions that most often appear on this topic.
How should an antiscalant be selected for my water?
Based on raw water analysis, recovery of RO and membrane performance parameters. It's best to start with a water test.
How can you tell that RO membranes are at risk of scaling?
The signal is a decrease in efficiency, an increase in pressure difference, a deterioration in permeate quality and a more frequent need for chemical lavage.
Does an antiscalant replace proper pre-filtration?
No. Antiscalant protects against salt precipitation, but filtration and control of iron, chlorine and suspended solids remain crucial to membrane life.
How often should the antiscalant dose be checked?
The dose should be verified when changing the quality of water, recovery, flow or pressure. Constant control reduces the risk of oversized and under-sized.
Can you help select treatment chemicals for an existing RO system?
Yes. We analyze water, operating parameters and the history of the accident. On this basis we choose anti-scalant and recommendations for station service.
