Filter Structure

Stainless Steel Sintered Mesh Filter, also called Metal Mesh Sintered Filter, Alloy Mesh Filter, Sintered Layer Filter, along with porous powder sintered filter element, fiberglass sintered filter element, and PP/PE sintered filter element, all belong to the broad category of sintered filter elements.

The sintering mesh filter usually has five layers of stainless steel woven wire mesh, including one protective layer, one filter layer, one separating layer, and two supporting layers. Can also add a skeleton layer according to the conditions sometimes.

Here are the functions of each layer.

Protective Layer--80~100μm

With a high mesh density, its main function is to intercept large particulate impurities, preventing them from entering the next filter structure, serve as the preliminary filtration and protection.

Separating Layer--40~60μm

Pre-filtering the medium-sized particles, separating the fluid, prevents localized clogging. It can adjust the flow rate of the filter media to reduce the filter pressure on the main filter layer, and extend the sintered mesh filter's service life.

Filter Layer--2~20μm

With a uniform pore size distribution, it is used to control the filtration precision, ensuring stable filtration from 1 to 300 microns, serve as the main filtration function.

Supporting Layer--200~300μm

High-strength coarse metal wire mesh, provides mechanical strength, increases the pressure corrosion and stability of the sintered mesh filter element. To prevent the deforming or cracking of the main filter layer under high pressure.

Skeleton Layer--thickness 1~2mm

High thickness metal plate, espacially suitable for the high pressure working condition. Withstand the system pressure shocks, to prevent interlayer misalignment and
ensure the sinter filter' shape stability, serve as a whole supporting function in the sintered mesh filter cartridge.

Cleaning Methods of Sintered Mesh Filter

The stainless steel sintered filter elements require standardized cleaning and proper daily maintenance during regular use to extend their service life.

Physical Methods

► Backwashing--Use clean water or compressed air to flush out impurities from the pores and surface of the filter element by introducing it from the outlet end in the opposite direction. Suitable for removing surface particles, sediment, and dust-like impurities. The pressure is at a range of 0.3 - 0.6MPa, the flow rate should be large enough to produce a strong flushing effect, but not so large as to damage the filter element.

► Ultrasonic Cleaning--Place the filter element into an ultrasonic cleaning tank filled with cleaning solution. The high-frequency vibrations of the ultrasound will dislodge impurities from the surface and interior of the filter element. The ultrasonic frequency is typically between 20 and 80 kHz, and the cleaning time is generally 15 to 30 minutes. This method is suitable for cleaning fine particles, oil sludge, and gelatinous impurities from micropores.

► Mechanical Brushing--For filter elements with stubborn stains or large particulate impurities on their surface, you can gently brush the surface of the filter element with a soft brush after backwashing or ultrasonic cleaning. However, be careful not to apply too much force when brushing, as this may damage the filter element's mesh structure.

Chemical Methods

► Acid Cleaning--When the filter element surface contains metal oxides or scale-like impurities such as calcium and magnesium, acid cleaning can be used. Commonly used acid cleaning agents include hydrochloric acid, nitric acid, and citric acid. The acid is prepared into a solution of a certain concentration, and the filter element is immersed in the acid cleaning solution for a period of time, and then rinsed thoroughly with clean water.

► Alkaline cleaning--When the filter element is contaminated with oil or organic matter, alkaline cleaning is an effective cleaning method. Alkaline solutions such as sodium hydroxide or sodium carbonate can be used, typically at a concentration of 5% to 15%. The filter element is immersed in the alkaline solution and heated appropriately for 1 to 3 hours, and then rinsed with clean water until neutral.

► Surfactant cleaning--For organic contamination, cleaning can be combined with the use of surfactants or enzymes (high concentrations of citric acid can be used in the food and beverage industry).

High-temperature Roasting

When organic matter is severely carbonized, the residue can be removed by high-temperature baking. This method is suitable for high-temperature operating conditions and high-temperature-resistant filter elements. The baking temperature is generally ≤450℃, followed by a period of heat preservation and then natural cooling. It should be noted that not all sintered mesh filter elements are suitable for this method; the suitability depends on the material.
