Citric Acid Water Softener vs Salt (Comparison)

The choice between citric acid water softeners and salt water softeners has been a topic of ongoing debate. To shed light on this topic, let us first explore the workings of citric water softeners and compare them to traditional salt-based systems.

Citric acid water softeners use citric acid to eliminate the minerals in hard water that cause scale buildup. This process is known as chelation, which binds to the minerals and prevents them from attaching to pipes and appliances.

In contrast, salt-based water softeners use an ion exchange process, whereby resin beads replace the minerals in hard water with sodium ions.

Determining which system is better largely depends on individual preferences and circumstances. Salt water softeners are effective at removing minerals, but require salt and regular maintenance to operate efficiently.

On the other hand, citric acid water softeners require less maintenance and do not require the use of salt, making them more eco-friendly.

In summary, choosing between citric acid water softeners and salt water softeners depends on several factors, including individual preferences, maintenance requirements, and environmental concerns.

By understanding the differences between these systems, individuals can make an informed decision that best suits their needs.

Hard Water

Hard water is a term used to describe water that contains elevated levels of mineral ions, including calcium, magnesium, aluminum, and iron.

These metals can dissolve in water and react with other materials, often leading to unsightly spots on faucets and the formation of scum when combined with soapy detergents due to the presence of insoluble metals and salts.

Household objects such as sinks, bathtubs, plumbing fixtures, and washing machines can be adversely affected by hard water, causing damage over time. Water softening is a process that involves removing mineral ions such as calcium and magnesium to alleviate the harmful effects of hard water.

Nuvo H20 presents a unique water softening solution that deviates from the traditional salt-based method. By utilizing citric acid, Nuvo H20 offers a convenient and effective way to soften hard water.

With over 30 years of commercial experience, Nuvo H20 technology has successfully addressed complex water issues while remaining compact and cost-effective. Unlike traditional water softeners, Nuvo H20 requires minimal maintenance, is environmentally friendly, and does not rely on electricity or wastewater.

The technology employs a chelation process that binds the citric acid to the minerals present in water. This active particle in citric acid prevents the buildup of scales that may negatively impact households.

In contrast to salt-based softeners, which eliminate mineral ions, Nuvo H20’s method works by binding them. This approach ensures that the minerals are not discarded but instead remain in the water, contributing to its overall mineral content.

Process Of Softening Hard Water Using Citric Acid

Hard water can cause mineral buildup in your home’s pipes, leading to clogs that can be harmful to your plumbing and appliances. However, there is a solution that can help you avoid these issues: Nuvo H20.

Nuvo H20 offers a two-pronged approach to hard water treatment. First, it balances the pH level of your water by using the natural acidity of citrus fruits. This helps to prevent the formation of scale, which can be seen as a buildup on your faucets.

Second, Nuvo H20 uses a process called chelation to remove mineral buildup in your water. When hard water passes through Nuvo’s flow media, calcium and magnesium minerals combine to form microscopic crystals.

However, Nuvo’s citric charge binds these crystals together, preventing them from forming scale. Instead, they break apart harmlessly and move through your plumbing without causing any damage.

In addition to preventing scale, Nuvo H20 removes the mineral ions from hard water that can react with soaps, detergents, and even your skin and hair. This can save you money in the long run by preventing the need for expensive repairs and replacements.

Nuvo H20 also includes a 20-micron carbon block drinking water filter to remove sediments, foul tastes, and odors, ensuring that your water is not only free of mineral buildup but also tastes great. With its proven effectiveness and reliable technology, Nuvo Citrus Charge Technology is the solution to your hard water problems.

The discharge of resin from salt-based water softeners can result in the accumulation of salt in aquatic environments, which can have adverse effects on streams, rivers, and lakes.

These ecosystems already experience elevated levels of salt due to human activities, including the use of road salt, and the discharge of salt from water softeners may exacerbate this situation.

Thus, it is important to be mindful of the potential impacts of water softener discharge on aquatic environments and to take steps to mitigate any negative consequences.

Saves Space

Unlike traditional salt-based water softeners, salt-free water softeners do not rely on high-capacity drinking water filters, nor do they require large amounts of salt. With a salt-free system, you can say goodbye to heavy loads of salt and bulky tanks that take up valuable space.

Furthermore, salt-free water softeners offer the added benefit of requiring only one cartridge to replace three years’ worth of salt, making maintenance much easier and cost-effective in the long run.

So if you’re looking for a low-maintenance, space-saving solution for your water softening needs, a salt-free water softener might be the perfect choice for you.

Wastes No Water

Water softeners that employ salt as a means of extracting minerals tend to consume a significant amount of water, nearly 25 gallons (94.6 liters) on a daily basis, for the regeneration process.

However, Nuvo H2O’s innovative approach to water softening sets it apart from traditional salt-based softeners. Rather than removing minerals and replacing them with sodium, Nuvo H2O’s system preserves the minerals, resulting in a smooth, refreshing sensation after showering.

Salt-based Water Softeners

This water softening system employs an ion exchange process to transform hard water into soft water. The conventional water softeners operate by replacing the calcium and magnesium minerals with sodium or potassium ions. In addition, resins are also obtainable for extracting bicarbonate, sulfate, and carbonate ions.

Once all the magnesium and calcium ions have been fully replaced with sodium ions, the exhausted system requires a regeneration process. During this stage, the accumulated minerals are discharged and disposed of, and the system is recharged with fresh sodium ions.

Following the ion exchange process, the wastewater containing the magnesium and calcium salts is then released to a sewer for proper disposal.

The following is how a recharge process occurs:


Here, water is directed through the resin opposite from the usual flow. Then it is disposed of through a drain. This process removes solids and, in turn, expands the resin bed. This process takes about 10 minutes.

Brine Draw

Water runs through a jet pump, which pulls the saltwater from the brine tank. This process usually lasts around 30 minutes.

Here water continues to flow from the inlet to the outlet, slowly flushing out the brine out of the resin bed. The flushing continues for a while, first at a slow pace than at a faster rate.

This goes on for close to an hour, it gets to a point and then the tank is filled with fresh water.

Using Lime as a Softener

This process occurs when lime is added to the hard water to get rid of the mineral ions. This has several advantages over the ion exchange; however, it is mostly used for commercial treatment purposes.


Achieving a healthy lifestyle starts with maintaining a consistent supply of clean, healthy water. Investing in a water softener can provide the assurance that you are effectively reducing harmful contaminants and chlorine in your water, regardless of your specific water needs.

Beyond the benefits of reducing chlorine, a water softener can also help to extend the lifespan of your appliances and improve the overall quality of your daily life. With softer skin and hair, as well as enhanced taste in your food and drinks, you can experience a noticeable improvement in your overall well-being.

The use of citric acid in a water softener provides maximum contact time with contaminants, ensuring thorough reduction of unwanted minerals in your water. Additionally, these systems are environmentally friendly and cost-effective to maintain, making them a sustainable choice for those seeking to improve the quality of their water and overall health.

Does Water Softener Resin Wear Out

The salt-based water softener and the salt-free water softener are equally effective water softeners. If you want a salt-based water softener, you will have to deal with periodic maintenance and its purchasing cost and installation.

Remember that this water softener is effective for large-scale water treatment and in areas with a lot of salt.

If you care about your environment and health, consider purchasing a salt-free water softener. It is less expensive, easy to install and overall easy to maintain.

However, it is ineffective in removing some minerals like lead and chlorine. Either way, get a water softener that suits your needs.

However, it is not all negative. It has health benefits, as magnesium and calcium are critical for the body. Calcium helps prevent hypertension, obesity, stroke, and kidney stones and strengthens bones, among other benefits.

Magnesium has its benefits for the body too. Softening hard water removes these two minerals.

According to a study, people who drink a lot of soft water have health issues such as high blood pressure, weakening of their bones, and more heart problems than those who drink hard water.

The inadequacy of these minerals can cause serious health issues. If you are considering using soft water, consider adding these minerals to your daily diet to ensure a healthy body function.
