What Is a Porous Sparger ?
What Is a Porous Sparger?
When hearing the word porous sparger, maybe you are a little confused. In this part, we mainly list the definition of porous sparger for you.
A porous metal sparger is a stainless steel element that can generate air bubbles. Its role is to produce a uniform air flow and to diffuse bubbles of a specific size. It effectively dissolves gases into liquids without interruption.
The special structure of sintered metal powder filter has millions of tiny pores on its surface. This creates an infinite number of small bubbles. The product has a wide range of applications in almost any industry. It is needed for any process that requires dissolving a gas into a liquid
What Is the Working Principle of Porous Sparger?
How does a porous sparger work, here we have an answer for you.
The porous sparger ensures the distribution of the gas in the liquid through thousands of tiny pores. The sparger produces smaller but more bubbles than the drilled tube and other sparging methods. The surface of the porous sparger has thousands of holes, causing a large amount of gas to pass through a specific location in the liquid.
What Are the Main Application of Porous Sparger?
Porous sparger plays an important role in industrial production and has been applied to many aspects. In this part, we list some applications for you to learn more about porous sparger.
①The sparger can create smaller bubbles than traditional spargers with sufficient accuracy, usually ranging from 0.5 to 12 microns. And it can be used in the fermenter, like wine production, to improve cell growth in fermentation reactions by sparging oxygen.
②Food and Beverage
Sintered porous sparger, mainly used to transfer gas into a liquid, can be widely applied in the food and beverage industry. For example, introducing CO2 to beer will extend the beer's life. And sparing nitrogen to replace oxygen, juices and oils will have a long life.
③Oxygenation
With high porosity of up to 55%, our porous sparger can generate more gases than the common sparger. So it is ideally used in fish ponds or aquariums to introduce oxygen.
④Pharmaceutical Industry
We always use safe and non-toxic metals to fabricate porous sparger. When you need a sparger in the pharmaceutical industry, you can choose an ozone sparger, by spraying ozone, the water system will be disinfected and adverse effects reduced.
⑤Green Chemical Industry
Normally porosity design ranges from 0.5 to 12 microns. Our sintered porous sparger can achieve high efficiency in transferring gas into the liquid. Using it in the green chemical industry can create more high-quality oxygen to maximize oxygen availability with minimized cost.
⑥Microalgae Process Plant
Microalgae is widely used in cosmetics, food supplements or the pharmaceutical industry as raw material. The porous sparger is an ideal choice to increase the production rate of microalgae biomass and products in a photobioreactor. Therefore, you can obtain large profits with fewer costs.
⑦Bioreactor
HENGKO air sparger can be better used in the bioreactor with better chemical properties. Our sparger will offer sufficient air or pure oxygen for the bioreactor, improving this reaction created by enzymes or organisms.
⑧Hydrogenation
You can use HENGKO's porous sparger to sparge hydrogen for a series of chemical reaction processes, like hydrogen water filter and hydrogen-rich water maker. Furthermore, nano-sized hydrogen bubbles will be generated, making them easier to combine with water molecules.
After reading the above-mentioned, maybe you have known that sintered porous sparger have been used in many industries. If your industry has a strict requirement of health and safety, we recommend you HENGKO sintered stainless steel porous filter made of stainless steel 316L, which has passed the FDA food grade certification.
Recommendation of Porous Sparger
If you are confused about how to select a good porous sparger, we recommend you choose HENGKO 316L stainless steel porous sparger which has passed the FDA food grade certification. Here we list two of them for you in the below.
①Stainless Steel 316 Micro Spargers and Filter in Bioreactors and Fermentors
The function of the bioreactor is to provide asuitable environment in which an organismcan efficiently produce a target product .
* Cell biomass
* Metabolite
* Bioconversion Product
The air sparger is used to break the incoming air into small bubbles. The sparger is configured with a uniquely designed adapter to allow easy assembly to the mating sparger tip and easy removal for replacement after each batch. This eliminates the need to re-weld the tip or clean the entire assembly. The spargers are durable and corrosion resistant, and the porosity of the media provides exceptional mass transfer efficiency throughout the tank.
Feature：
l 316L material, food grade, safe and durable;
l Bubble size produced-10-100 times larger thanpores;
l It performs in high temperatures, corrosive environments and provides mechanical stability;
l It can survive an almost unlimited number of sterilisation cycles or can be discarded after each campaign.
Application: Used mainly on a largescale fermentors
②Sintered Microsparger in Bioreactor System for Green chemistry industry
The importance of aeration and gas dispersion to achieve good oxygen mass transfer cannot be understated. This is at the heart of the ability of microbial systems and to a lesser extent cell culture systems to provide the necessary respiration for active cell growth and metabolism.
The micron sparger ring is equipped with 20 micron (or choose smaller micron ) micro spargers for a maximum flow of 0.1 VVM air and 0.1 VVM oxygen. These micro spargers provide small bubble size under the pitched blade impeller where they are mixed into the broth to achieve homogenous dispersion and maximize availability of oxygen for mass transfer into the cells.
Application：
l Aquaculture
l Cosmetics
l Human nutrition
l Pharmaceuticals
l Food supplements
l Natural pigments
In conclusion, through this passage, you probably know a porous metal sparger is a stainless steel element that can generate air bubbles. Its role is to produce a uniform air flow and to diffuse bubbles of a specific size. It can effectively dissolve gases into liquids without interruption. Porous sparger has been applied to various industries such as food and beverage, green chemical industry, bioreactor etc. When you choose a porous sparger, a 316L stainless steel porous sparger is good.
