For a very long time, filtering has been a crucial stage in the winemaking process for wineries of all sizes all over the world. Before being bottled for distribution and consumer sale, this method aids in achieving the best texture, taste, consistency, and stability for wines.
The mainly two reasons to filter wine are aesthetic and microbial. When we got wines that are not that perfect, we can do a filtration to make them have better performance in glass and in our mouths.
But when residual sugar or Malic acid were found in wine, or even worse, Acetobacter or Brettanomyces were found during the ageing/storage period, filtration is no longer a choice. To save the wine, we must filter it and make sure the microbial stability for the wine.
The pore size of filters is measured in microns and the typical winemaking sizes are 5, 3, 2, 1, and .45 micron media. The filter is claimed to be “tighter” as the pores get smaller. According to the fact that the pore size can be made smaller than actual yeast and microbes, microbial stability is guaranteed by filtration.
The larger microorganisms become trapped and are removed from the wine as it passes through the filter. But one thing you should notice, 0.45um filters are used to remove yeast and Coli bacillus, and 0.2um filters are needed to remove bacteria.
There are still many different filtration systems in use today, and in the future are expected to see many advancements in wine filtering methods and procedures.
The methods employed to achieve certain flavors, aromas, and full-bodied characteristics of various wines frequently differ significantly from one another, just as there are significant differences between the wines made by various wineries.
Filters are rated as being “Nominal” or “Absolute”. A nominal filter will remove most particles that are equal or greater than the rated micron size.
An absolute filter will remove all particles larger than the micron rating. Nominal filters are cheaper than absolute ones, and if you are only doing a general cleaning up of the wine, a nominal filter may be all you need.
However, if you are filtering to remove either yeast or bacteria, you will need to rely on an absolute filter. You should notice that n absolute filter is only needed at the final filtration of the wine. It is frequently the final filtration step before wines are bottled for sale and consumption.
As the micron size decreases, filtration’s impact on wine becomes more obvious. Filtration does remove some components from a wine, but these components are frequently worth sacrificing.
A wine may experience stress from filtering and momentarily “fall apart” as a result. Filtered wines, however, overcame “bottle shock” just fine over the course of the subsequent weeks.
Filtration set-ups are based on the two different forms of filtration media: cartridges and pads. Cartridges use housings, whereas pads require a “plate and frame” set-up.
Both these methods require a pump to move the wine, but small lots can also be done without a pump using a keg and pressurized gas if you have this equipment.
Cartridges are more expensive than pads because they are more intensive to produce, but they can be cleaned and stored for future use. Pads are cheap but they can only be used for one time.
Both pads and cartridges are useful and practical, so choosing between the two technologies just comes down to personal working preferences.
The cartridges are easy to clean and reuse though they cost a lot in begin. Also, and they take intensive time for maintenance. Pads are economical and somewhat messy, however when you‟re finished you just need to throw them away. Additionally, only cartridges can provide .45 Absolute ratings. In other words that you cannot achieve a sterile filtration using a plate and frame set-up with pads.
The production of wine is a hard and complex process. From the grapes to the grape juices, from the juices to wine, lots of steps must be done, of course, filtration is one of the most important procedures. Filtration, to some extent, decides the texture, quality, and taste of the wine.
In the winemaking industry, Brother Filtration is pretty important. We provide dependable filter media and equipment for all stages of wine filtration based on our extensive depth of filtration experience.
For many well-known vineyards across the world as well as for quality-conscious winemakers. Depending on the type of wine and winemaking style, variations may be also taken into account.
The ocean occupies most of our planet, and desalination has been used more and more widely over the past 20 years. By using reverse osmosis systems, we help desalination plants to do their job and further help more plants to solve the problem of water shortage.
Every chemical plant is inseparable from industrial water filtration systems. Whether it is the purification and filtration of raw materials and final products or the treatment of industrial wastewater and unwanted chemicals generated during the production process, industrial filtration is a top priority.
Most petrochemical industry products are stored in large containers, such as diesel, gasoline, and fuel oil. This type of storage is highly likely to lead to impurities in the products and affect the product quality. Our mission is to offer efficient and reliable filtration systems for the petrochemical industry so that purification is not a big challenge.
The extremely rapid growth of the pharmaceutical industry has created a greater demand for industrial filtration. Whether it’s upstream cell fermentation, purification, or filtration, we can provide the solution. In addition, We are committed to filtration and separation, protecting the reliability and safety of production equipment.
The food and beverage industry is closely related to the daily life and health of each of us. Therefore, we must meet higher standards to filter these products. As your experts, we help you improve product quality, reduce production costs, and safeguard everyone’s health.
Nature itself has the ability to treat wastewater. But with the huge increase in human production and living activities, it can no longer handle such large amounts of wastewater. We, as industrial treatment producers, help nature to share the burden of wastewater treatment.
Industrial wastewater from mining activities contains high volumes of heavy metals, particulates, and residual chemicals. Wastewater must be purified and filtered in order not to pollute our water resources. We help your plant meet wastewater discharge standards.
In order to extract oil more efficiently and conveniently, large amounts of water must be injected underground to ensure water pressure. And since precious water resources are limited, our technology allows wastewater to be purified so that it can be reused.
When it comes to marine filtration, the first scene that appears in people’s is usually the sea or seawater. But marine filtration is more than seawater. A crucial resource on this planet is seawater. Large amounts of seawater are needed to generate fresh water for drinking and irrigation in locations with a lack of fresh water, just as ships sailing on the ocean need a lot of it for ballast water to keep the ship balanced. Marine filtration is not only about the seawater, but also the transported seawater. The ballast water is a kind of transportation of water. The cargo ships load the seawater from one place and discharge it at another port. The seawater traveled with the cargo ship in ballast tanks. This is the point many people will be indifferent about, the filtration before the discharge of the ballast water. People are familiar that we can not drink seawater directly, because it contains large quantities of salt and contaminants. But why do we need filtration for ballast water? it is just the seawater discharge into seawater. With the development of the environmental protection concept and the perfection of the law, we are constrained to filter the ballast…
The science and practice of extracting metals or metal compounds from minerals and transforming them into metallic materials with specific qualities using a variety of processing techniques is known as metallurgy. With the development of technology and the metallurgy industry, the filtration market in this area grows quickly annually. The need for filtration is increasing and the filter equipment is also developing. In the metallurgy industry, the rolling mill coolant and lubricate system need a filtration system. Equipment coolant and lubricating oil need to be filtered to remove contaminants and accomplish recycling in the metallurgical process in order to save input costs.
