Alumina airstones, a great selection of aeration products available at Aquamerik. Contact us if you wish for more information about our products.
We truly believe that an Alumina airstone diffuser resists 3 times longer than the silica diffusers, (force of tension: 1450 PSI). This force contributes to increase its longevity. Aluminum oxide is indeed way less soluble in the water. Since aluminum oxide is more resistant to chemicals, Alumina diffusers can be washed with muriatic acid and are tougher than silica. Moreover, it is possible to use less chemical products by washing organic materials with a flame. The thermal resistance of Alumina diffusers enables you to do it. Silica diffusers can’t be cleaned with a flame, since a “quartz inversion” happens, which causes a cracking of the diffuser. Aquamerik guarantees the Alumina diffusers for a period of 2 years. The Alumina diffusers are the best diffusers manufactured for the industry of aquiculture, water treatment and the applications of lake aeration. With an air resistance of less than 0.25 psi, they can be used with low pressure economical blowers; they produce small uniform bubbles, their weights prevent them to float and they are extremely resistant to clogging.
A little bit of theory…
Let’s take this example. We have a big bubble (20mm) with a volume of 4.19 cm³ and a surface of 12.6 cm². By dividing the large bubble, we get 296 small bubbles and an area of 83.6 cm². This aerates 6.6 times more water with the same volume of air produced. The perfect diffuser must provide small bubbles with a minimum of pressure drop to be sufficiently heavy to sink and does not have to clog. This perfect diffuser already exists… the solution is the Alumina airstones!
