Not all salt is the same, and using the wrong kind can cost you down the road. From system efficiency and equipment lifespan to long-term maintenance expenses, the type of salt you choose has ripple effects.
Let’s explore the most common salt options for commercial water softeners, break down their pros and cons, and help you decide which is the most efficient and cost-effective solution for your operation.
Before we get into recommendations, let’s look at the options typically used in commercial water softeners. While all soften water, they each work differently based on how they’re processed and the purity levels they offer.
Rock salt is mined straight from the ground and minimally processed. It’s often the cheapest option available and might seem appealing from a cost standpoint. However, rock salt contains higher levels of insoluble minerals, which settle in your brine tank over time. This buildup creates sludge that requires more frequent cleanouts and can clog your system.
Pros:
Cons:
Solar salt is created by evaporating seawater using sunlight. It’s naturally formed, environmentally friendly, and, most importantly for commercial operations, extremely pure. At 99.8–99.9% sodium chloride, solar salt offers a clean burn with almost no residue. This purity means less sludge, better brine quality, and a healthier brine tank and softener system. It’s an excellent choice for high-capacity systems that need long-term reliability.
Pros:
Cons:
Evaporated salt is produced through a high-energy process that removes nearly all impurities. While it boasts the highest purity level, it’s also the most expensive salt option on the market. Because of its cost, evaporated salt is usually reserved for specialty or laboratory-grade applications that require ultra-pure softening, far beyond what most commercial operations need.
Pros:
Cons:
Pellet salt is made by compressing refined salt into uniform, hard pellets. It’s often marketed for residential use but is sometimes used in smaller commercial systems. One thing to note: pellet salt contains a binding agent to help it keep its shape. Over time, that gumming agent can lead to buildup or clumping in the brine tank. While cleaner than rock salt, it doesn’t outperform solar salt in larger commercial applications.
Pros:
Cons:
For most commercial operations, solar salt strikes the best balance between performance, cleanliness, and long-term value. Facilities using solar salt often notice better water clarity, smoother equipment performance, and less frequent maintenance.
It’s clean, easy on equipment, and works seamlessly with Jet Powered Salt Delivery systems like SaltCo’s, which deliver high-purity salt directly to your brine tank without dust or waste.
Because of its high purity, solar salt doesn’t leave behind the same sediment or sludge that rock or pellet salts do. That means your maintenance teams won’t need to clean out the brine tank as often, and your system won’t have to work as hard.
Using lower-quality salt leads to buildup, which can affect the float valve, injectors, and other parts of the softening system. Facilities using solar salt typically see fewer clogs, better system pressure, and fewer service calls overall.
Even though it costs more per pound than rock salt, solar salt pays off. Reduced downtime, lower maintenance costs, and increased system lifespan often outweigh the initial investment. This makes solar salt the more economical option when you consider the total cost of ownership.
Your water softener is only as good as what you put in it. That’s why the type of salt you use has a direct impact on how long your equipment lasts, and how well it performs. Over time, lower-grade salts can leave black sludge or mineral crusts in your brine tank, which leads to extra work for your maintenance staff. It can also reduce system efficiency by blocking the flow of brine or interfering with the regeneration process.
If your system is regenerating inefficiently or you’re seeing performance dips, your salt might be the issue. Many of these problems can be avoided entirely by switching to solar salt.
Technically, you can use any type of salt with most commercial water softener systems. But that doesn’t mean you should. While many systems are compatible with various salt types, what matters more is how well the salt maintains long-term system performance. Solar salt is often the best choice for facilities using automated or high-capacity systems, especially when paired with Jet Powered Salt Delivery. However, bulk salt delivery is also a popular method for larger scale industrial facilities.
SaltCo’s delivery system is built around solar salt. It’s designed to deliver clean, pure salt directly to your tank from outside the building, with no mess and no manual hauling. That ensures consistent brine quality and eliminates the operational issues caused by lower-grade salt.
