Adding Filter Media to Upflow Neutralizers

Yesterday, we described how to add filter media to a back-washing calcite neutralizer, with or without a top fill plug. Today, we’ll explain how to replace filter media in an acid neutralizer upflow system, with or without a top fill plug. First, let’s look at the differences between upflow and downflow neutralizers.

In a standard downflow neutralizer, water enters the top of the tank, flows down through the media, and backs up the distributor tube. The downflow-type neutralizer removes sediment and can be backwashed, cleaned, and re-classified, thus preventing channeling.

During backwash, the water flow is reversed. Water flows down the distributor tube and up through the media, lifting and expanding the calcite media. The water's action cleans the calcite

In an upflow neutralizer, the water always flows down the distributor tube and up through the calcite media.

Upflow neutralizers have no backwash control valve and are not backwashed because water is always flowing up through the calcite—as such, there is no need for a backwash.

This type works well in some applications and prevents the need for any backwash drain connection. However, the upflow types often have problems with channeling, wherein the calcite media partially solidifies, channeling water around the filter media and reducing the filter’s effectiveness.

Calcite media in these systems need to be replenished periodically to maintain effectiveness.

A bypass valve is essential for the neutralizer system's easy connection and operation. It allows for optimal system performance during setup and when adjustments are necessary.

Now, as for adding calcite media to an upflow neutralizer:

Adding Calcite to Up-Flow Type Neutralizers with or Without a Top Fill Plug

1. Begin by putting the neutralizer filter on bypass or turning the water pressure off before the Neutralizer. Then, open the faucet or hose bib downstream of the neutralizer to release pressure in the tank.
2. Unscrew the media fill plug with channel locks or pliers and siphon 2 to 3 gallons of water out of the filter tank using a tube or hose. If you don’t siphon the water out, when you add filter media, water will flow out the fill plug hole and onto the floor. If water on the floor is OK, you do not have to siphon water before pouring calcite media into the top fill plug hole.
3. If there is no top fill plug, unscrew the top tank manifold to access the tank.
4. Place a cap or wrap tape over the distributor tube, and add neutralizer filter media until the tank is 2/3 full. Do not over-fill: Be sure to leave at least 12″ of free space above the media to allow room for the media to expand during a backwash.
5. Remove the distributor tube cap and reinstall the top fill plug or tank manifold. Close the valve after the upflow neutralizer so no water can flow to the house. Open the hose bib after the neutralizer and slowly turn on the water to the Neutralizer. Allow the water to run slowly at first for 10 minutes, then turn on the water to full force and rinse the media thoroughly for 20 minutes before putting it into service, if possible.

Understanding Acid Neutralizers

Acid neutralizers are essential water treatment systems designed to neutralize acidic water by raising its pH level. They utilize naturally occurring minerals, such as calcite, to correct the pH of acidic waters. This process is crucial for protecting plumbing systems, appliances, and overall water quality from the corrosive effects of acidic water. Water with a pH of less than 7 is considered acidic and can cause corrosion damage. These systems help prevent corrosion damage by neutralizing acidic water and maintaining balanced water chemistry.

Acid neutralizers, including calcite and neutralizing filters, are widely used in residential and commercial applications. Calcite filters function as acid neutralizers for water with low pH levels, effectively raising the acidity of water while introducing beneficial minerals like calcium and magnesium. Neutralizing filters often use calcite as a key component, protect plumbing systems, and maintain water quality. They provide a reliable solution for maintaining a noncorrosive equilibrium in typical plumbing systems. Additionally, acid neutralizers can be used in conjunction with other water treatment systems, such as water softeners, to offer a comprehensive approach to water treatment. This combination ensures that your water is neutralized and softened, providing optimal water quality for your home or business.

How Upflow Neutralizers Work with Calcite Media

Upflow neutralizers operate by slowly dissolving calcite media in acidic water, which in turn increases the water’s pH level. This process involves the water flowing down the distributor tube and up through the calcite bed. As the acidic water flows through the calcite bed, the calcium carbonate dissolves, releasing calcium and magnesium ions that neutralize the acidity. This interaction results in a noncorrosive equilibrium, making the water safe for typical plumbing systems.

The role of upflow calcite in maintaining a noncorrosive equilibrium is crucial. It ensures the water's pH is raised without overcorrection, preventing metal leaching from plumbing.

One of the benefits of using calcite media is its self-limiting property, which prevents over-correction of the pH level. However, it’s important to note that this process can increase water hardness. To ensure continuous effectiveness, the calcite media must be periodically replenished. Upflow neutralizers also help reduce the potential leaching of copper from plumbing systems, further protecting your pipes and fixtures. Overall, neutralizing acidic water with calcite is a natural and effective way to maintain balanced water chemistry.
