Table of Contents Introduction Sintered filters are produced through a sintering process, where materials such as metal powders, ceramic, or polymer fibers are subjected to heat and pressure, bonding them into a solid, homogeneous structure. These materials are typically formed into tubular shapes via molding or isostatic pressing, often eliminating the need for cores. This […]
Table of Contents Introduction Compressed air filtration is a key element in the production and utilization of compressed air. By removing contaminants such as solid particles, moisture, oil, and other pollutants from the air stream, it ensures access to high-quality compressed air with minimal contamination. One of the primary contaminants in compressed air is oil. […]
Table of Contents Introduction Coalescer filters are used to protect industrial equipment and processes from damage caused by liquid pollutants. These contaminants can cause corrosion, clog pipes and equipment, and reduce process performance. Coalescers are an important part of industrial filtration systems. which have various uses in industries such as oil and gas, petrochemicals, power […]
Table of Contents Abstract Natural gas always contains a certain level of contamination, and it must meet strict quality requirements before use. Based on the contaminants present, it is classified into two categories: sweet gas or sour gas. Sweet gas poses fewer issues and is preferred for sale and transportation, while sour gas requires further […]
Table of Contents Desalination is commonly used today to address freshwater shortages in certain regions of the world where saline water is available. Over the past century, various technologies have been introduced. This article examines current commercial technologies such as Multi-Stage Flash Distillation (MSF), Multi-Effect Distillation (MED), and Reverse Osmosis (RO), as well as emerging […]
Table of Contents This article focuses on technologies and equipment related to the filtration of large water flows and wastewater treatment that occur in daily flows at medium to large scales, highlighting recent advances in the corresponding technologies. Applications of large-scale water treatment share common characteristics. They all have relatively high flow rates that require […]
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 […]
Purification of air entering gas turbines is crucial due to various reasons. An optimal filtration system is necessary for gas turbines due to reasons such as preventing erosion and prolonging the lifespan of the turbine. Preventing erosion and deposits on the compressor blades Reducing corrosion along the air path Reducing hot gas corrosion Protection against […]
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 […]
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 […]
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. […]
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 […]
Nanotechnologists have discovered new filtering media for effective filtrations. The nanofiber-based filtering media, made up of fibers of diameter ranging from 100 to 1000 nm, can be conveniently produced by electrospinning technique. This article addresses the current state of the art in filters by using nanofibrous filtering media. These filtering media are being surface-modified to […]
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 […]
