Stainless Steel Titanium Rod Filter

The titanium rod filter adopts a titanium powder sintered filter element and is generally used for rough filtration or intermediate filtration. This filter element has the advantages of high precision, high temperature resistance, corrosion resistance and high mechanical strength, and is widely used in the pharmaceutical industry. The shell material is 316L or 304 stainless steel, which complies with GMP standards.

Applications

This filter is characterized by high pressure resistance, strong acid resistance, strong alkali resistance, corrosion resistance and reusable regenerable filter elements. It is a hollow filter tube made of titanium metal powder through high-temperature sintering via powder metallurgy technology. It is widely used in solid-liquid separation in food, beverage, pharmaceutical, chemical and other industries. Especially in the pharmaceutical industry, it is suitable for decarbonization filtration in large infusion and injection production lines. This series of products are manufactured in accordance with GMP standards with a compact structure and an attractive appearance. The pipe connections adopt international standard clamp-type connections for easy disassembly, assembly and cleaning.

Precautions for Use

Avoid scratches, collisions, dust and oil contamination.

During operation, the working pressure shall not exceed the rated working pressure.

In normal use, there shall be a low-pressure start-up time of at least 3–5 minutes, and the relative pressure difference shall be controlled below 0.5 MPa. Then gradually adjust the working pressure to the required level (the maximum pressure shall not exceed 0.4 MPa).

After a certain period of operation, the filter element may be clogged, resulting in increased pressure and reduced flow rate. Backwashing or reverse cleaning regeneration is required. The regeneration cycle depends on the rated pressure and flow rate.

Cleaning Methods

After a period of use, the titanium rod filter element will be clogged to a certain extent, which is characterized by reduced flow rate and increased pressure at the filtration front end (e.g., rising from below 0.22 MPa to above 0.3 MPa). At this time, the filter element needs to be cleaned. Common cleaning methods are as follows:

For newly used filter elements, backwashing with clean water and back blowing with gas are generally adopted, i.e., flushing with clean water at a pressure slightly higher than the working pressure (e.g., 0.3 MPa) in the reverse direction. The backwashing time is about 1–3 minutes.

If the filtration effect does not improve significantly after multiple backwashing, soak the filter cartridge in hydrochloric acid solution (≤5%), sulfuric acid solution (≤8%) or sodium hydroxide solution (≤10%) at room temperature, then rinse it thoroughly with clean water.The specific choice of acid cleaning or alkali cleaning shall be determined according to whether the impurities in the filtrate are easily soluble in acid or alkali.

Main Performance Characteristics

Excellent airtightness, compact structure and not easy to damage. It is suitable for harsh working conditions in the production site with no maintenance cost.

No adsorption loss of filtration solution, adsorbent and catalyst, and no change to the original components of the working medium.

Non-toxic, non-magnetic, non-shedding and good biocompatibility. Due to these properties, the titanium rod filter is widely used in the pharmaceutical, food and beverage industries.

Small floor space, high temperature resistance and good oxidation resistance. It is suitable for high-temperature precision filtration of various acids, alkalis, salts and organic solvents.

Easy disassembly and assembly. The filter has a scientific and diverse structure to meet various filtration requirements.

High filtration precision, capable of one-time filtration of particles above 0.2 microns.
