Self Cleaning Filter

What is Self Cleaning Filter

 

 

Self cleaning filters utilize system pressure to clean themselves. The rigid cylinder screen inside the filter strains the particles from the water source, trapping the debris inside. This buildup can cause differential pressure from the inlet to the outlet.Self-cleaning filters come with many advantages, but perhaps the biggest of them is that they are low maintenance, and because of this they are an excellent choice for remote sites since they require no operator intervention. Another major benefit of industrial self-cleaning filters is that they clean themselves while the system is still running. This saves the user money, energy, and time. They also generally have a compact design which allows for flexibility during installation.

Application of Self Cleaning Filter
 

Food Processing Industry

You may use a self-cleaning filter to eliminate toxins from your food to ensure the protection of food during processing. Various foods require various filters that you can use to ensure that pollutants are removed.
Self-cleaning filters are used here for their functions and also because they can store some viable fouls that can be used in other parts and for other functions.

Power Generation

There are various power generation areas in which a self-cleaning filter may be used. For example, a self-cleaning filter is required in turbines to ensure effective and efficient fluid flow. Also, a self-cleaning filter is required for removing pollutants from the oil in the electric generators. You can produce electricity continuously because the filter allows steady work.

Water Treatment

For our consumption and other household tasks, we all need clean water. This calls for us to handle the water we use until we drink it. You can eliminate pollutants, including unwanted particles, from the water by using a self-cleaning filter. Different unwanted particles may be extracted from the water, making them safe to use depending on the size of the filter product. Using a self-cleaning filter in water treatment plants ensures that water treatment stays uninterrupted. This is due to its ability to clean itself.

Sewage Treatment

We all know how precious water is and how necessary it is to be stored and recycled, if possible. One method is by wastewater treatment. Sewage water treatment requires many measures that function successfully with the use of a self-cleaning filter. The benefit is that sewage water is constantly treated. Sewage water treatment facilitates water use in a variety of applications; an example is the provision of water for irrigation in farms.

Farming

It is very important to circulate water on your farm, and this is typically required at a continuous flow rate. The need to constantly have this water flowing is why the filter capable of self-cleaning is commonly used in the farm's water system. A typical example, the animals on your farm will have to drink clean water. This water might have been polluted and might pose health risks to them. You will have to use a filter, and, in this case, it must be a filter that can allow a long process of work while it stores the pollutant. The irrigation of your farm is another field of use. You will need plenty of water to irrigate your farm, which can often be polluted like rivers. Therefore, before the water flows into the farm, you must eliminate the pollutants. This can be done using a self-cleaning filter that removes impurities and allows clean water flow to your farm. The size of the filter used will depend on the size of the pollutants you wish to eliminate.

 

What Are the Components of an Self Cleaning Filter
 

Motor

There must be an energy force that pushes the fluid forward to ensure that the filter functions properly. This energy is generated by the motor to clean the filter. You have to be careful about the size of your filter and the application when picking an engine for your self-cleaning filter. The motor must be able to guarantee enough energy to pump your fluid and not interrupt your application.

Inlet and Outlet Valve

The inlet valve is that part of the self- cleaning filter that lets in fluid during filtration. Depending on the scale of your application, there are different sizes of inlets one can have. You can ensure that the flow of fluid is maintained with respect to pressure by selecting the correct inlet scale. In contrast, the outlet is the self-cleaning filter part, which allows the fluid to flow from the filter. The fluid flows out from this point after filtration is done.

Filter Element

The self-cleaning filter component that holds unwanted particles and contaminants while filtering is known as the filter element. There are different filter elements sizes, and they are designed depending on the filtration quality of the fluid you want. You may also have a number of filter part materials. You must constantly check for any necessary maintenance because they are the most active part of your self-cleaning filter.

Suction Nozzle

The suction nozzle dumps the dirt in the dirt collector. Depending on the filter form you choose, there are various types of suction nozzles. The air suction nozzle, the water suction nozzle, and the oil suction nozzle are all in the market.

Drain Plug

Another component of the self-cleaning filter is the drain plug. In cleaning the filter, the drain valve plays a significant part. This part can be found at the bottom of your filter. This component removes contaminants from the filter, and this makes sure your filter works constantly.

Collector of Dirt

Once the filter accumulates dirt from your fluid during filtration, the pumping of the contaminants into the dirt collector happens. In the meantime, you don't need to remove and dispose of the dirt collector until it is full. The aim is to ensure the continuity of the application process and to achieve maximum output.

 

Types of Self Cleaning Filter

Self-Cleaning Air Filters
This kind of filter is important for purifying the air we breathe in, especially in air cleaning applications. They are used to making the air breathable and to remove the toxins. They are used in the coupling of air conditioners, vents, masks, etc.

 

Self-Cleaning Oil Filters
You should use a self-cleaning oil filter to filter the oil you put into equipment that requires constant oil filtration. You may use a self-cleaning oil filter for different appliances and machinery. For example, using a self-cleaning oil filter ensures the continuous functioning of industrial machines and equipment. This requires consistent production and ensures clean oil. In addition, you need a self-cleaning oil filter to filter your oil in the automobile industry. This ensures the efficiency of vehicle engines.

 

Self-Cleaning Water Filters
Self-cleaning filters are a form of filter for the elimination of toxins in water. You will find them in water circulation systems like sewage processing stations and water treatment facilities. These types of filters use the disparity in water pressure to clean themselves. What occurs is the flow of water through the inlet to the filter part. The contaminant, which is greater than the pores of the filter element, is stuck with the filter. This process continues until the water pressure differs. Air-operated ventilations open up, which redirect water flow back to the pores of the filter elements. This is usually referred to as backwash. In this way, the water will flush the contaminants on the element. In this method, the self-cleaning filter can be cleaned up repeatedly. Self-cleaning water filters consume below 1% of the water, making them efficient.

 

 

How Does A Self Cleaning Filter Work

In general, the fluid flows from the intake valve into the screen and then to the outlet during standard operations. The cleaning disc at the top position of the screen closes when fluid flows into the screen. The rinsing valve also closes to ensure that the fluid is filtered. At this point in the process, impurities begin to build up and, as filtration continues. Failure to remove the impurities may result in your self-cleaning filter not working to the optimum level, and this is done by decreasing the pressure of the fluid. That is, you must continuously remove the impurities. The change of pressure is sensed through the control unit, which is typically located on the side of the self-cleaning filter.


The control unit initiates the rinsing valve's opening. Once the rinsing valve is opened, the contaminants flow away from the screen. The power machine begins to close the cleaning disc. This, in essence, will increase the speed of the fluid between the disc and the screen. Due to the Bernoulli effect, the pressure will decrease at this point. This pressure decrease causes particles from the screen to be separated and drift upwards. After completion, the cleaning disk moves up to an idle position that cleans the screen further. The rinse valve shuts down while the cleaning disk is inactive so that the machine comes back to normal function.


To ensure continuous operations, the fluid is continuously circulating through the whole process. Friction will easily cause the filter components to wear out. This means that you also have to continue sourcing new components. Cleaning the disc and monitoring the screen so that they don't touch each other is a way to mitigate this. This is the general working theory of a self-cleaning filter.

How to Choose Self Cleaning Filter
 

Understand Your Filtration Application
Begin by clearly defining your filtration requirements. Are you dealing with water, oil, chemicals, or other fluids? What is the particle size range you need to remove? Understanding your application's specific characteristics will help you determine the necessary filtration capacity and level of filtration.

 

Determine Filtration Rating
Based on the particle size you want to remove, determine the required filtration rating in microns. This will help you narrow down filters that can effectively capture particles within your desired range.

 

Flow Rate
Flow rate is the rate at which fluid passes through the filter. It's crucial to choose a self-cleaning strainer with a flow rate capacity that matches or exceeds your application's requirements. An undersized filter may lead to clogs and decreased efficiency.

 

Research Filtration Technologies
Different self-cleaning screen filters employ various technologies like backwashing, screen cleaning, and pulse-jet cleaning. Research these technologies to understand how they work and their suitability for your application. Consider factors like energy consumption, maintenance requirements, and filtration efficiency.

 

Maintenance Frequency and Downtime
One of the primary advantages of auto self-cleaning filters is their reduced maintenance requirements. However, different filters have different maintenance schedules. Consider how often the filter needs cleaning and the associated downtime. Choose a filter that aligns with your operational schedule.

 

Material Compatibility
Make sure that the construction materials of the filter are compatible with the fluid being filtered. Using materials that are not compatible can result in corrosion or chemical reactions, which can compromise both the filter and the fluid being filtered.

 

Energy Consumption
Automatic self-cleaning filters require energy for the cleaning process. Assess the energy consumption of the filter's cleaning mechanism and factor this into your operational costs.

 

Precautions for Installing Self Cleaning Filter

 

When installing the equipment, first of all, attention should be paid to the protection of the control box, sensor and transmission part of the equipment to avoid damage to these places.

 

When installing the self-cleaning filter body, it is necessary to connect the pipeline in accordance with the direction indicated by the arrow on the body, so that the direction of the equipment water will be consistent with the arrow on the body.

 

Install the self-cleaning filter at the same time. Before you need to protect water equipment, be sure to get as close as possible to the water equipment.

 

In the power system, the self-cleaning filter should be installed in the middle of the water pump and water equipment, and the closer to the water equipment, the better, the pressure between the water pump and water equipment exceeds the pressure of the filter, the self-cleaning filter can also be installed before the water pump, and to try to close to the water pump.

 

There are two ways to connect the automatic blowdown valve of the equipment, one is flange; Two: silk buckle. The length of the blowdown pipe should not be too long, and the length should be controlled within 10 meters.

 

At the same time of installation of equipment, must take into account the late maintenance, so in the installation of self-cleaning filter should be installed shut-off valve, and should also be installed by the bypass pipeline. The two sides of the self-cleaning filter should be set aside enough maintenance space, especially in the filter barrel, should be set aside close to the length of the cylinder, in order to facilitate the replacement of the filter screen in the later period.

 

The specifications of the self-cleaning filter and pipe or flow to match, if a single filter can not meet the requirements of the system can not meet the flow requirements of the system, also have to parallel two or more, easy to meet the requirements of the system filtration, take any one of the installation methods, should pay attention to the automatic blowdown valve outlet direction is horizontal or downward, Better guarantee the effect of sewage discharge.

 

When the self-cleaning filter is installed outdoors, it is necessary to take into account the reasons of the weather and pay attention to the rain weather.
