Filtration fundamentals
Table of Contents Introduction Air filters play a crucial role as integral components of HVAC systems, industrial equipment, and air pollution control technologies. They are essential for improving environmental air quality and protecting sensitive components of machinery, such as turbines, by ensuring clean airflow. With the continuous rise in air pollution and the rapid advancement […]
Table of Contents Introduction The EN 779 standard is a European standard that is used to test air filters in air conditioning systems. This standard classifies filters based on their performance in removing particles from the air. The first version of this standard was compiled in 1993 and is used as a general guide for […]
This article aims to shed light on the issue of pressure drops in filtration systems and offers effective solutions to manage and enhance the efficiency of the filtration cycle. Pressure drop is a common problem that hampers the fluid flow rate and reduces pressure during the filtration process, which can negatively impact the performance and […]
Filtration is a crucial process in many industries that helps to remove unwanted materials from a fluid stream. A filter element is an essential component of filtration systems that comprises three main parts: media, support, and filter body. The media is the primary component of a filter element and typically consists of a porous surface. […]
Filtration is a crucial separation process utilized in various industries to remove unwanted materials from fluid streams. There are several ways to perform filters, based on different mechanisms. In Mechanical filtration, unwanted materials are removed from the fluid stream based on their size or shape. In chemical filtration, impurities are separated from the fluid stream […]
It is important to understand that, only considering the micron size of particles for a filter is insufficient. The micron size is not very important without measuring the efficiency of the filter media in a given particle size. It can be said that a regular roll of paper may also stop 10-micron particles, but with […]

Introduction of magnetic force To understand how magnetic filters work, it’s helpful to have a basic understanding of magnetic forces. This will give you insight into the nature of magnetic forces and their usefulness. Magnetic forces occur between two magnetic objects and can be either attractive or repulsive, depending on the alignment of their magnetic […]
The quality of the air inlet of the turbine is a critical factor influencing the performance and life of the gas turbine. Consequently, it is essential to implement a filtration system to manage air quality by eliminating pollutants present at the turbine inlet. Given the numerous factors involved, selecting an appropriate filtration system can be […]

Abstract Microfiltration (MF) is one of the oldest and most widely applied pressure-driven membrane processes, based on the physical separation of particles, microorganisms, and colloids in the size range of 0.1–10 μm. Due to its relatively low operating pressure, ease of operation, and high separation efficiency, MF has found extensive applications in water treatment, food […]
Absrtact Membrane filtration technology introduces a novel separation approach that cannot be achieved using conventional filter media. Membranes—classified into microfiltration, ultrafiltration, nanofiltration, and reverse osmosis—play a critical role in various industrial applications, including petrochemical processes, water treatment, pharmaceuticals, and food processing. These membranes, manufactured from cellulosic, polymeric, or ceramic materials, enable separation at molecular and […]
