Your Leading Aeration Stone Supplier in China

Filson aeration stone is an industrial tool that increases the contact aera between air and water. It is made of porous material with pores all over the surface. Its function is to inflate the water through the aeration stone to form many bubbles, to increase the water solubility of the gas.

According to the traditional aeration method, the contact area of gas-to-water is very limited. The forced transfer of oxygen from the air to water in order to obtain sufficient dissolved oxygen in the water. It may be difficult to achieve, however, Filson aeration stone can help you deal with the problem.

Obviously, if the gas coming out of the device can be ‘smashed’ to the ‘granular’ state, it will be more effective to increase the contact area and realize a higher diffusion efficiency. Filson aeration stone works as the same principle: the air through the stone is distributed to the liquid in the form of millions of tiny bubbles and dissolved rapidly.

Filson aeration stone is applied to all sorts of industries to reach the purpose. The common applications in life are to introduce oxygen to fish tanks ( fish farming, aquarium ) to enhance the solubility of the gas and activate the water in the tank.

Another familiar way to use a Filson aeration stone is to aerate chilled wort prior to fermentation. By doing this, the yeasts inside your wort get enough oxygen to support their growth. The same goes for beer brewing.

People Also Ask

What is an Aeration Stone?

Aeration stone is a versatile industrial and commercial tool, sometimes also called air stone, bubble, or diffuser. The aeration stone comes in many shapes, sizes, and micron levels. Usually, the stone is made of stainless steel powder experiencing a sintering process to finally form a porous stone.

The main purpose of an aeration stone is to gradually diffuse the air, oxygen, ozone, or other gases into the target liquids. You can see millions of microbubbles through your water with the help of a pump and tubing.

The sintered aeration stone does not clog easily and gives a better distribution of air with tiny bubbles than other types of aeration systems. These sintered stones are very durable and extremely easy to clean. Basically, they are safe for all types of application conditions, like ponds, freshwater aquariums, beer, and marine fish tanks.

How to Use an Aeration Stone?

Aeration stone is an important device for wort aeration. It puts oxygen into the wort, which is necessary for the yeast in fermentation to build healthy cell membranes. Without oxygen, the yeast can not form as strong cell membranes, and this may lead to off-flavors in your beer.

Of course, correctly use of an aeration stone is also vital to beer brewing:

  • Get a suitable pump for your wort aeration to provide enough power.
  • Clean and sanitize everything, including the aeration stone that will contact your wort.
  • Connect the aeration stone to your aeration system.
  • Before aeration, remember to chill your wort below 26℃.
  • Put the aeration stone near or at the bottom of the wort and start to aerate.

Warm tips:

  1. Beers with higher gravity solubilize oxygen at a slower rate than average gravity beers. And the operation may take a litter longer.
  2. Keep foaming to a minimum level.
  3. The optimum wort oxygen level is 8 to 10 ppm.

Pay attention that smaller bubbles are better than big bubbles, this comes to the right selection of the aeration stone, you can consult Filson for more information.

How do I Know When to Change My Aeration Stone?

Aeration stone is a porous media that has the risk of blockage, after a period of use, you are recommended to change your aeration stone. But how to tell if you need a new aeration stone? You can take the following points as a reference:

  • The number of bubbles coming out of your aeration stone has decreased.
  • Your aeration stone is no longer silver, instead, it is a little orange, brown, or a darker color.
  • The bubbles coming out of your aeration stone are obviously larger than they used to be.
  • The bubble rise velocity is slower compared to the speed when it started to use.

Generally, an aeration stone lasts for years, and it can be replaced or changed every three to six months in order to maintain the proper function of your tank.

What Can I Do to Clean My Aeration Stone?

While most people choose to replace the aeration stone regularly, it is also possible to clean the stone to rejuvenate its effectiveness and restore it for a longer time. The right cleaning methods not only save your purchasing costs but also improve the aeration efficiency.

  • Rinse the aeration stone in freshwater for a while, gently scrub contaminants off the surface, and then allow the stone to air dry.
  • You can also simply clean the aeration stone by boiling it for about ten minutes and then air dry completely.
  • Clean your stone by chemical soaking. Put the aeration stone into a solution of one part bleach and three parts fresh water for one day for both cleaning and sterilizing. ( If your stone is clogged badly, soak it for another 24 hours. )
  • After soaking, remove the aeration stone from the bleach solution. Connect it to an air pump and place the stone in freshwater, allowing it to run for several minutes. This step will dilute and clean the residual bleach from the device.
  • Take the stone out of the water and let air pass through the stone for five minutes to dry.
  • Finally, store the aeration stone in a clean plastic bag for the next use.

You can also use hydrogen peroxide to clean the stone. Vinegar solution may be more effective if your water has mineral content, it will help remove the calcium lime deposits clogging the pores. Avoid drying the stone by using an oven or microwaving, it’s not useful for cleaning the insides and may cause damage.

How Long do Aeration Stones Last?

It depends.

Aeration stones last for many years for their optimized process condition and advanced sintering technology. However, as the increased times you use it and the conditions ( mineral content or something ) of your process liquids, the service life of the stone will be shorter.
