How to Remove Aluminum from Water [YEAR] (5 Methods)

Aluminum is a metal that’s found naturally in low concentrations in water sources.

It’s also often added to water due to the use of aluminum-based coagulants in water treatment plants.

In this story, we’ve shared a quick overview of aluminum and discussed the 5 best methods to remove aluminum from water.

Reverse Osmosis Systems

Reverse osmosis is the most effective way to remove dissolved aluminum. You can buy a reverse osmosis system to install under your kitchen sink or on your kitchen countertop.

Anion Exchange

Anion exchange reduces aluminum in drinking water by swapping negatively charged ions, known as anions, with others in the water.


KDF-55 filter media is commonly used in water filters and purifiers and is specially designed to target heavy metals in drinking water.

This media is a combination of copper and zinc granules, which instigate an oxidation-reduction (redox) reaction that can effectively remove certain contaminants, including aluminum, from water.

During this redox reaction, electrons are transferred between aluminum contaminants and the KDF-55 media.
