Filter Filtration

Filter filtration" is used in a wide range of applications from everyday life to medical and environmental fields. This article summarizes the mechanism, applications, features, and types of filter filtration.

What is Filter Filtration?

Liquids, slurries, vapors, gases, and other substances to be filtered are poured into a "filtering material" such as a filter filter or membrane to separate specific substances.is "filter filtration. The filtration mechanism is used in a variety of fields, from coffee drip to large wastewater treatment plants.

Filter filtration is used for different applications, depending on the size of the material that can be collected by the filtration method. Depending on the purpose, a single filtration operation may be sufficient, while others may require multiple filtration operations.

Filter Filtration Mechanism

How does filter filtration work?When the material to be filtered is poured into a "filtering material" such as a filter or membrane, the target material is captured.It is called.

The reason why the target substance can be captured is that depending on the structure and properties of the "filter material," some substances can pass through the filter material while others cannot.

The filter material may have a complex mesh structure, microscopic gaps, or properties that allow only certain substances to pass through.

For example, when using a filter material with microscopic gaps, larger substances cannot pass through the filter material and are trapped on the surface or inside the material. Only those substances that are able to pass through the filter media are collected as liquid or gas after the filtration process. This is how filter filtration separates certain substances.

Filter Filtration Applications

Applications of filter filtration include

The applications of filter filtration are diverse, ranging from the familiar to advanced scientific fields.

Evolution of Technology! Filter Filtration Case Study

We have introduced the applications of filter filtration and found that it can contribute to solving problems in a variety of fields. Now, we have gathered case studies of companies to further confirm the filter filtration technology.

Filter filtration contributes to solving blade manufacturing issues

In the grinding process of industrial machine blades, removal of carbide fine sludge in the grinding fluid and its control has been an important issue. This contributes to improved machining accuracy and productivity, longer equipment life, and a better working environment. Sun Maintenance Koki's microfiltration equipment and filters address these challenges and provide consistent support, including sludge recycling. This allows us to respond flexibly to environmental issues and to change from water-soluble grinding fluid to grinding oil.

Filter filtration for virus removal in biopharmaceuticals

Virus removal filters are used to remove viruses from biopharmaceuticals, and their manufacturing process requires high quality and uniformity. AI technology is being implemented in the manufacturing of the filters to analyze manufacturing data, improve quality control, and increase efficiency. ai is being used to reduce variation in the manufacturing process and produce products of more consistent quality. This innovation is being driven by collaboration with engineers on the manufacturing floor.

The Case of Filter Filtration in Science

The plant uses metal-less filters for filtration of highly corrosive-resistant hydrochloric acid solutions. The filter is completely sealed and operates fully automatically, effectively removing the resin from the wastewater, thereby reducing the risk of blockages in the wastewater treatment plant. This technology significantly improves the safety of the working environment and production efficiency. Since no metal is used, the filter can also be used for acidic liquids.

Filter Filtration Features and Types

There are four types of filter filtration

Rough filtration is used to capture large objects and uses a depth filter that captures the object on the surface and inside of the filter. Microfiltration, ultrafiltration, and dialysis/reverse osmosis use a screen filter, which traps objects on the surface of the filter.

There are three types of "screen filters": membrane filters, ultrafiltration filters, and dialysis/reverse osmosis membranes.

Membrane filters are used in microfiltration to remove bacteria and viruses. The surface of the membrane filter has microscopic holes that do not allow larger substances to pass through. Therefore, larger substances are trapped on the surface of the membrane filter.

Compared to the "depth filter," the gap is narrower, so the filter must be pressurized when filtering. Also, if there are too many objects to be captured, the filter will quickly become clogged, so it should be filtered in advance with a pre-treatment filter.

Ultrafiltration filters are capable of capturing smaller substances than membrane filters. They are often used to concentrate viruses and proteins. There is a front and back side, and the side that captures the object is called the skin layer. When filtering, be sure to pour the substance to be filtered through the skin layer.

Dialysis membranes and reverse osmosis membranes are used for dialysis and reverse osmosis, and can trap almost all substances except water molecules. They are often used for desalination of seawater.

Summary of Filtering with Filters

Filter filtration has a wide variety of applications ranging from the familiar to advanced scientific fields, depending on its characteristics. It is important to select the appropriate filtration filter according to the characteristics, purpose, and application of the filtration object.
