Reversible Titanium Rod Filter

Product Overview

A titanium rod filter uses hollow filter elements manufactured from titanium powder through a high-temperature sintering process based on powder metallurgy technology.

The titanium filter element offers high filtration accuracy, excellent high-temperature resistance, strong corrosion resistance, and the ability to be repeatedly cleaned and regenerated for reuse.

Working Principle

When the process fluid enters the filter housing through the inlet, impurities are first retained on the outer surface of the titanium filter element, gradually forming a dense but permeable filter cake. This filter cake also contributes to the filtration process.

Particles smaller than the pore size of the titanium filter element may enter the microporous structure of the filter wall. Because the internal pores consist of numerous narrow, curved, and interconnected channels, particles entering these passages are easily trapped.

In addition, compression and impact caused by fluid flow cause fine particles to adhere to the internal walls of the pores. This filtration mechanism takes place within the titanium filter element and is therefore classified as depth filtration.

Impurities are retained both on the outer surface and within the porous structure of the titanium filter element, while the clean filtrate flows out through the outlet.

As contaminants gradually accumulate, the pressure inside the filter increases. When the operating pressure reaches approximately 0.3 MPa, the titanium filter elements should be cleaned and regenerated.

Applications

Titanium rod filters are widely used for solid-liquid separation in industries including:

• Food processing
