The beta value (Beta Ratio) of a filter is a measure of its effectiveness in removing particles of a certain size. It is often used to quantify filtration performance and is specified by indicating the ratio of the number of particles before and after filtration. The formula for the beta value is: Beta Ratio  = Number of particles before filtering\Number of particles after filtering ​ The higher the beta value of a filter, the more effective it is at removing particles from the flowing medium. A beta value of 2 means that the filter removes half of the particles, while a beta value of 100 means that the filter removes 99 out of 100 particles. Beta values ​​are often used in various filtration contexts, especially when evaluating the performance of filter elements in relation to particle removal. It is important to note that the beta value is specific to a given particle size and that different filter types and filter media may have different beta values ​​for different particle sizes. It is also relevant to know that the beta value is usually used in industrial contexts rather than in household filtration.
Consult with filtration experts, consider the specific requirements of your application, and evaluate factors such as flow rate, particle size, and maintenance needs to determine the most suitable filtration system for your needs. Contact us +46 31 92 20 70 sales@ifab.se  
Yes, liquid filtration plays a vital role in wastewater treatment by removing solid particles and impurities before the treated water is released into the environment.
Some advanced filtration methods, such as reverse osmosis and ion exchange, can effectively remove dissolved substances from liquids. Depending on what kind of substance.
Activated carbon is used to adsorb organic impurities, odors, and color from liquids. It is commonly employed in water and air purification processes.
Yes, many liquid filtration systems incorporate automation for efficient and consistent operation. Automation helps control parameters such as flow rate, pressure, and cleaning cycles. Automatic filters such as Amiad or Tekleen, all use automated backwashing. Backwashing involves reversing the flow of liquid through the filter to dislodge and remove accumulated particles. It is commonly used in granular media filters. Please contact us for more information +46 31 92 20 70. sales@ifab.se
Steril filtration is a filtration process specifically designed to remove or reduce microbial contaminants, including bacteria, viruses, and fungi, from liquids or gases to achieve sterility. The goal of steril filtration is to produce a product that is free from viable microorganisms, ensuring the highest level of microbial control. Common methods include membrane filtration & depth filtration. Steril filtration is widely used in various industries, including pharmaceuticals, biotechnology, food and beverage, and healthcare. It is applied to critical processes where maintaining sterility is essential.
Mechanical filtration is a method of separating particles from a liquid or gas by using a physical barrier or filter. This happens by preventing the particles from passing through the filter material due to its structure or pore size. Mechanical filtration is one of the oldest and most basic forms of particle separation and is used in a variety of applications.
Membrane filtration is a separation process that uses a semi-permeable membrane to selectively allow certain components to pass through while blocking others based on their size, shape, and molecular weight. This method is commonly used for purifying liquids, concentrating solutions, and separating different substances. There are various types of membrane filtration processes, including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Common methods include gravity filtration, pressure filtration, vacuum filtration, and membrane filtration, each suited for specific applications and particle sizes.

Common questions

Virtually any liquid, including water, chemicals, oils, and beverages, can be subjected to filtration to remove unwanted particles. The choice of filtermaterial is more and less compatible and is adapted to specific liquid.
Liquid filtration is a process used to separate solid particles from liquids, ensuring the removal of impurities to achieve a cleaner and purer liquid. Liquid filtration is crucial for various industries to meet quality standards, remove contaminants, and enhance the performance of liquids in processes such as manufacturing and water treatment.
