Filtration is an important process in the purification of liquids. It removes solids and impurities from liquids and makes them safe for use. There is multiple filtration methods used in industries today. The appropriate method for each industry depends on the type of liquids that require filtering. Another factor is the size of impurities and solids present in the liquid.
Some filtration’s take more time per cycle, which is where Membrane plates come in handy. The filtration plates shorten the time per cycle and make the overall process more efficient. Let’s look at the types of membrane filter plates:
Fixed Membrane Filter Plates
Fixed membrane filter plates are generally used in the food industry. This type of filter plate does not have any joints. The lack of joints prevents contaminants from getting into the liquid during the filtration process. Fixed membranes are available in two types of materials. The most common is a polypropylene material.
For certain applications thermoplastic is also effective. However, for common food and beverage applications polypropylene is the most efficient. Fixed Membrane plates are easy to replace. You can just purchase a replacement and install it. This is one reason they are popular in the food industry because reusing plates could cause contamination.
The beverage industry uses membrane filter plates for filtering juices, beer or wine. Membrane filters can separate even the finest particles from the liquid. When it comes to consumable liquids, one cannot take a chance at all. This makes membrane filters the most reliable for the food and beverage industry.
Pigments and Dyes
Industrial and food grade pigments and dyes also use a filtration system that uses membrane filter plate. When these dyes are manufactured, they have small lumps. When the dyes are passed through this type of filter, it purifies the dye and pigments making them pure and smooth.
Replaceable Membrane plates have more of an industrial application. The core of these filter plates is made of polypropylene. A rubber membrane goes into the core. You can also get thermoplastic cores. However, the commonly used and trusted cores are made of polypropylene. These types of filters are generally used to filter non-consumable liquids.
Therefore, the core remains the same, but the membrane itself can easily be replaced. This helps keep the filtration cost low, but it is not ideal for the beverage industry. This is because the replaceable core has joints, which could cause contamination. Rest assured, it is an excellent choice for filtering industrial liquids and chemicals.
The most common application for Membrane plates is the filtration of minerals. When these minerals are extracted from the earth, they are never pure. There are many impurities that have to be eliminated. Membrane filtration’s plates help remove the fine impurities present in minerals.
Treatment Of Waste Water
These filtration plates are also used in the treatment of waste water. Of course, for the water to be purified it has to be put through multiple filtration processes. But membrane filter plates are used to remove the solid particles.
Membrane plates have multiple uses. Just be sure to select the right one for your application. Selecting the appropriate filter will give you the best results.
