What is a high flow filter?

High flow filter usually refers to a pleated filter cartridge with a larger outer diameter and surface filtration area, it processes liquid at a faster flow rate, has a larger flow rate and stronger dirt holding capacity, can help users save on filtration system space. Compared to traditional 2.5″ OD filter cartridges and liquid filter bags, high flow filters save the labor cost and time in replacement, increasing system filtration efficiency at a lower cost.

When should you Replace a High Flow Filter ?

You should replace a hi flow filter cartridge when it reaches its maximum recommended service life or when it no longer effectively removes impurities from the water. Additionally, if you notice a decrease in water flow rate or a decline in water quality, it is an indication that the filter cartridge needs replacement. Regular maintenance and monitoring are crucial to ensure optimal performance and to prevent any compromise in the filtration efficiency of the high flow filter cartridge.

How can you Determine the ServiceLife of a High Flow Filter?

The service life of a filter is the period in which the high flow filter will remove contaminants before reaching full dirt holding capacity.

You must predetermine the dirt holding capacity of the filter at a given flow rate before you can determine the service life of a filter.

In some cases, the information is supplied together with the high flow filter cartridge.

Using this information, consult the test protocol graphs provided along with the filter to determine how long it will last.

However, the performance and period of service will vary from one application to the other depending on the fluid type and nature of contaminants.

Can you clean a high flow filter?

Yes, water cartridge filters are cleanable.You can either opt for a manual cleaning or automatic cleanable filter.

Manual Cleaning

Ensure that you shut down the system to allow the elements to cool before opening the filters.

Stop fluid flow using the shut off valve.

Remove the filter elements and scrub them using a brush or other compatible liquid to removed dirt.

Air-dry the elements before placing it back into the filter.

Alternatively, you can use ultrasonic cleaning or back washing with pressurized water/compressed gas.

Automatic Cleaning 

Automatic cleaning filters initiate self-cleaning when the pressure drop reaches a certain predetermined level.

Self-cleaning filters use different techniques to dislodge dirt off the elements.

In some screens, the dirty cartridges rotate and rub itself against the scrapper, which removes the particles.

The dislodge dirt is collected at the bottom of the filter in a collector

Self-cleaning filters can clean continuously without having to stop the filtration process and, therefore, suitable for operations that cannot stop.

For which industry high flow filter suitable?

  • Prefiltration for sea water desalination

  • Power plant condensate

  • Filtration of raw materials, solvents, and water in the biopharmaceutical industry

  • Filtration of bottled water, sugar liquid, edible oil, fruit juice, soft drink, milk

  • Paint, coating, petrochemical industry

  • Microelectronics, film, fiber, resin

High flow filter, also known as security filter, plays an important role in the field of pre-filtration water treatment and is widely used in sewage treatment plants, water treatment plants, industrial production and other fields. To process large amounts of water flow. This filter element features a collapsible design, high contamination capacity, excellent single-pass flow handling, easy replacement, and excellent strength characteristics. Due to these advantages, high flow filters are very popular in the filtration industry. But for buyers, how to choose a suitable high flow filter may be a key issue. This article will provide you with a practical guide on how to choose the right high flow filter.

Step #1. Understand application requirements

Start by defining your application needs, including the type of liquid (e.g., water, oil, chemicals), the type of contaminants that need to be removed (e.g., particulates, bacteria, organics), the standards that need to be met, and the required flow range. For example, the high flow filter commonly used in the food industry needs to comply with national health standards, and the filter element material needs to be safe and non-toxic and will not cause food contamination; the high flow filter used in the medical industry needs to comply with relevant medical standards to ensure that it can effectively filter bacteria and Viruses and other microorganisms, etc.

Step #2. Analyze water quality conditions

Analyze the water quality characteristics of your water source, including suspended solids concentration, dissolved substances, acidity and alkalinity (pH value), etc.; determine the concentration and size of contaminants that may be present in the water. Understanding the water quality conditions and characteristics of the water source is a key step in selecting an appropriate high flow filter to ensure efficient water treatment and contaminant removal. Water quality may vary from different water sources, so analysis and selection of the appropriate types of filters and specifications will need to be carried out on a case-by-case basis.

Step #3. Understand system parameters

Determine the temperature and pressure range of your system to ensure that the selected filter element can operate normally under these conditions; determine the diameter and connection method of the system pipes to select the appropriate high flow filter specifications.

Step #4. Select high flow filter type

According to the application requirements, select the appropriate filter element type, such as particle filtration, microbial filtration, activated carbon filtration, etc.; consider whether multi-layer filter elements are needed to improve filtration efficiency.

Step #5. Select high flow filter material

According to the water quality conditions and application environment, select the appropriate filter element material, such as PP, ceramics, fiberglass, stainless steel, etc.; consider the chemical resistance, heat resistance and corrosion resistance of the material.

  1. Polypropylene: Polypropylene filter element is suitable for filtering general particulate matter, such as sediment, suspended solids and particulate pollutants. They are generally less expensive and have higher adsorption capacity.

  2. Stainless Steel: Stainless steel filter element has corrosion resistance and high temperature resistance. And it is suitable for filtration requirements in harsh environments, such as high temperature and high pressure conditions.

  3. Ceramic: Ceramic filter elements are suitable for efficient filtration of tiny particles and microorganisms. They have high chemical and thermal stability requirements and are suitable for drinking water purification and some special industrial applications.

Step #6. Assess maintenance needs

Understanding the life and maintenance requirements of your chosen filter element. It is important in determining when it will be necessary to replace the filter element and the associated costs. This includes clarifying the expected service life of the filter element, maintenance frequency and specific maintenance procedures to ensure continued efficient operation of the system. Through careful maintenance planning, unnecessary maintenance costs can be reduced and potential problems can be prevented in advance,thus ensuring the reliability of the water treatment system.

Step #7. Cost considerations and supplier selection

When comparing prices from different filter models and manufacturers. It’s important to consider the cost of the filter itself as well as maintenance costs to ensure budget and performance requirements are met. In this regard, we strongly recommend you to choose Btlas’ high flow filter. Because it’ is not only competitive in terms of price of the filter element itself, but also performs well in terms of maintenance.

Btlas’ high flow filters are known for their efficient filtration performance and exceptional durability. Which means you can replace the filter element less frequently, thus reducing maintenance costs. In addition, Btlas offers a variety of models and material options to meet different application needs. And ensuring you get the best value for money.
