Water softeners are unique water conditioning systems because they use ion-exchange technology to trap and expel hard minerals from water. In order to achieve this process, water softening systems are designed to use resin beads. Water softener resin beads are the ion-exchange media used to implement the ion-exchange process that renders hard water, soft. Also known as sulfonated co-polymer of styrene and divinyl benzene, the most commonly used resin beads in the water softener industry are polystyrene-type gel resin beads, which are primarily polystyrene and divinylbenzene (DVB).
Although water softener resin beads are innovative and effectual, there are still some things that can go wrong with them. Continue reading to learn the top 5 types of failure mechanisms associated with water softener resin beads, and what you can do to resolve them all.
Water Hammer (Hydraulic Shock)
Water hammering, or hydraulic shock, occurs when the water softener’s high pressure water flow is disrupted. As a result of this sudden stop in water flow, the resin beads slam against the side of the brine tank, which damages their structural integrity. When resin beads are broken or cracked, they are simply not capable of being as efficient as they are designed to be.
As a result of water hammering, broken and cracked resin beads will attempt to repair themselves by filling in the holes with particulate matter. But this particulate matter can lead to “fines”, that eventually exit the system during the regeneration cycle, and thus, render the water softener less efficient in terms of ion exchange capabilities.
Osmotic shock occurs as a result of the swelling and contracting of resin beads during both the dissipation and regeneration cycle. After some time, this manipulation can cause the resin beads to crack or break. This causes lower temperatures and high backwash flow rate which is the condition in which osmotic stress occurs.
Oxidation (Chlorine Attack)
Oxidation, or chlorine attack occurs as the outer bands of the resin beads suffer damage, thus losing strength and swelling. The results are cracked and broken resin beads, which can lead to all the above-mentioned water softener regeneration issues.
Metal fouling refers to the oxidation that occurs when oxygen is introduced with brine. Because the iron oxide precipitant cannot be eliminated through backwash systems, so it creates blockages in the resin exchange sites. This altogether decreases resin operation and efficiency, and therefore, water softener performance.
