How to choose an Automatic Self Cleaning Filter? There are 2 methods for self-cleaning filter selection.
Select according to the cleaning method. Automatic Self Cleaning Filter can be divided into four types according to cleaning methods, namely backwash filters, brush self-cleaning filters, multi-column self-cleaning filters, and sucking self-cleaning filters.
Select according to the needs of use. Automatic Self Cleaning Filter can be selected based on the requirements of filtration equipment components, the required size of the number of filtration, and the degree of filtration in actual production.
Automatic Self Cleaning Filter is a popular automatic water filtration equipment in sewage treatment, which is used in municipal, industrial, agricultural and other fields. So, how to buy an ideal self-cleaning filter? Here are two types of selection techniques, which can be selected according to the cleaning method or usage needs.
1. Selection according to cleaning method
The introduction of Automatic Self Cleaning Filter has solved the problem of waste water, and in order to achieve better filtration effect, self-cleaning filters are also constantly being upgraded, and manufacturers have also developed different self-cleaning filters according to the characteristics of different fields. Here we can choose according to the cleaning method.
1.1 Backwash the filter. The backwash filter is an intelligently controlled filtering device. The backwash filter can be used for forward filtration and reverse backwashing, which can cope with unstable and fluctuating water quality, and can be used for filtration of difficult pollutants such as sludge and microfiltration.
1.2 Brush type self-cleaning filter. The brush type self-cleaning filter can design the corresponding pipeline interface according to different working conditions. The brush-type self-cleaning filter adopts PLC control system, high-performance precision filter element, etc., to realize automatic cleaning and sewage treatment, and this self-cleaning filter can provide uninterrupted water supply during the sewage cleaning process.
1.3 Multi-column self-cleaning filter. The multi-column self-cleaning filter generally uses a coarse filter to filter larger particles of impurities, and at the same time forms a pressure difference between the inside and outside the fine filter, and starts the process of automatic cleaning. This type of filter equipment is generally used to filter water floats, fine particles, etc.
1.4 Sucking self-cleaning filter. The sucking type automatic cleaning filter does not need manual help, it is a kind of intelligent filtering equipment, which can directly complete the three processes of filtering, cleaning and discharging. The sucking type automatic cleaning filter adopts mesh surface filtration, which can be cleaned intelligently, and the filter can be used for life.
2. Selection according to the needs of use
2.1 Combined with the requirements of equipment components. Because of the wide range of industries that need to be filtered, we must not only consider the material conditions, but also understand whether the filter is corrosive.
Such as the paper industry, they are very corrosive, so customers in this industry usually choose stainless steel components for filtration. If the filter is not very corrosive, other materials can also be used in the selection of equipment components.
2. 2 Combined with the required size of the filtered water. Different self-cleaning filters have different pipe diameters, and the amount of filtered water that the self-cleaning filter can satisfy is affected by many factors, such as the filter flow range, equipment diameter, and on-site piping conditions.
In order to avoid losses, the filter equipment of the corresponding diameter can be selected according to the amount of water to be filtered. Generally, the amount of water to be filtered is proportional to the size of the equipment. The larger the amount of filtered water, the larger the diameter of the equipment required.
2.3 Combined with the filtration degree of actual production. It is understood that in practical applications, the filtration precision that can be achieved by different types of equipment for Automatic Self Cleaning Filter is different, which is also the part that we need to pay special attention to when choosing.
Therefore, when choosing filtration equipment, you must first understand the degree of filtration required for production. For example, the precision range of the brush type self-cleaning filter is suitable for the filtration field with a filtration precision of 50-5000 microns.
