Filtration systems using sintered metal media for filtering corrosive liquids or gases prove to be an effective alternative to other separation approaches. It is less vulnerable to high temperatures, corrosive environments, and pressure spikes. 

Harsh environments often demand continuous operation of all-metal filtration systems for high-particle efficiency removal, efficient backwash capability, long service life, and reliable performance. Sintered filters are used for a variety of applications in oil refineries, chemical and petrochemical processes, and pharmaceutical production facilities.

What is Sintered Filter?

Sintered metal filter elements are designed to capture 0.5 from 100 microns with high efficiency of 99.9%. It comes in various shapes like cylinders, discs, cups, and tubes, each one carries useful properties and a precise filtration rating. It is comprised of a protective mesh layer, filter mesh layer, and an additional layer of protection on the outer side.

It creates a physical barrier between impurities and multiple types of fluids. During the removal of contamination, a reverse flow of gas is produced to dislodge microbes from the filter.

Principle Features and Properties

A sintered porous metal media combined with precise bubble point specifications, close thickness tolerance, stable porous matrix, and uniformity of porousness ensures great filtration performance. Controlled pores are crucial to ensure effective particulate removal from process streams, coupled with successive particle removal amid a backwash procedure. Particulate removal can help improve the quality/value of downstream liquid content or aid in continuous processing of the waste stream.

• High Precision – High particle removal efficiency with accurate and flexibility
• High-Temperature Resistance – All sintered metal filters can withstand a high temperature of up to 1000°C.
• Good Rigidity – Multi-layered sintered mesh for solid structure and mechanical strength
• Extended Lifespan – Easy to wash and backwash through years of continuous usage
• Custom Engineered – Type of materials, shapes, thickness, and micron rating depending on the application

Applications

Sintered metal media can be used in many separation applications. Below are some cases using a sintered filtration system:

Case 1

The filtration process is used to capture abrasive particles and reduce chemical oxygen demand in a crystal polishing application. Solids can be returned to the separator for minimal waste production and wastewater contamination.

Case 2

Sintered metal filtration technology provides an alternative to centrifuges for catalyst recovery applications. Filtration offers excellent filtrate quality of suspended solids and backwashes concentrated solids for recovery. 

Case 3

Sintered metal media can be used in resin handling systems for polishing wastewater recovered from resin blowdown and removal of resin, crud, and iron oxides. It carries high-end stability characteristics, even in harsh conditions, making it suitable for nuclear applications.

Case 4

Sintered metal filtration media is utilized in the downstream petrochemical and fine chemical industries. A filtration mechanism is installed in purified terephthalic acid procedures to enhance production yield, product quality, and diminish loading of the waste treatment unit.

Final Words

Sintered porous metal filter components are highly recommended for vigorous applications to capture particles ranging from 0.5 to 100 microns.
