7-Stage Water Filter System: Activated Alumina is ideal for turning water into something better. With its seven stages, you can easily access mineralized, alkalized, and fluoride-free water.

Every stage of the filter contains different amazing water filters that ensure you have clean and safe drinking water every time. This article will discuss one of the seven filters in our 7-Stage Water Filter System, the Activated Alumina.

Activated alumina is a typical desiccant with excellent adsorption capabilities, making it suitable for various domestic and industrial uses. We'll take a deeper look at the use of activated alumina in water filters in this blog post.

What is an Activated Alumina?

Activated alumina is a water treatment device at the point of entry or the point of usage. Instead of screening pollutants, activated alumina absorbs them. Experts determine the efficacy of activated alumina by the impurity, alumina properties, device design, and water quality.

Activated alumina may be an efficient treatment for water supply with a high total melted solids level or a high concentration of sulfate. But one significant disadvantage of employing activated alumina is that it needs strong acid and basic solutions for regeneration, which are unsuitable for home handling and storage.

How does it work?

When water passes through the activated alumina media, pollutants such as fluoride, selenium, and arsenic absorbs attaches to the alumina. It leaves the water free of these dangerous chemicals.

When activated alumina is disposed of, it will "adsorb" rather than "absorb" the contaminants, not discharge the bound toxins back into the environment.

You can usually find a packed bed of activated alumina granules in activated alumina devices. It absorbs certain pollutants when water travels through the equipment.

You can determine its efficiency by the chemical form of the filtered contaminant. For example, you're chlorinating the water before activated alumina treatment. It will transform arsenic into the most likely to absorb in certain circumstances.

The effectiveness of activated alumina treatment is influenced by pH. The pH of the water should be less than 8.5 in general. A pH of between 5 and 6 is ideal for fluoride. The recommended pH for arsenic is 7. For activated alumina to work, it may need pretreatment to lower the pH.

Where to use it?

Desiccants, such as activated alumina, often adsorb water molecules in the air or gases to keep objects dry and reduce humidity levels.

It's used in compressed air dryers as a cost-efficient desiccant to absorb water molecules under extreme circumstances.

Alumina also works as a catalyst in the purification and dehydration of hydrogen peroxide gas and gasoline throughout the production process.

Another common application for activated alumina is a water filter to remove or minimize pollutants like fluoride, selenium, and arsenic from water, widely used in domestic, commercial, and industrial water treatment applications.

Some people also use it to dry gases like propane to transfer safely without corroding or leaking.

It cleans up toxic wastes and rains. It also filters groundwater to eliminate soluble metals like lead and compounds like arsenic due to their great adsorption capabilities.

What Does pH Levels Have To Do With Activated Alumina?

PH levels heavily influence the effectiveness of the Activated Alumina treatment. For the greatest results, the pH level should be below 8.5.

Pretreatment of the water to regulate the pH levels can help the Activated Alumina water purifying process go more smoothly and produce better results.



Because activated alumina may bind with harmful contaminants, the toxic pollutants will not seep into the environment during disposal.

In other words, the effect of utilizing activated alumina to remove harmful pollutants is permanent, not transitory.

As a result, it's a cost-effective and environmentally friendly method of removing hazardous chemicals from water and cleaning the environment.

That's why water filters commonly use activated alumina filters to remove fluoride, lead, arsenic, and selenium.

Furthermore, it is a very stable chemical, which means that when it bonds with harmful substances. It will not change its structure or chemistry, even in high-temperature or corrosive settings.

7 Stage Water Filter System: FINAL THOUGHTS

Activated alumina filter is a very absorbent form of aluminum oxide. Because of its microporous nature and large surface area, it's suitable for purifying various substances, including water. Activated alumina media is often used as a water filter in water filtration systems to remove fluoride from drinking water. It can efficiently minimize fluoride levels from 10 ppm to less than one ppm.

The more time the water is in contact with the media, there will be more fluoride it removes.
