Titanium Water Filter

Sintered porous metal filters are precision filtration components manufactured from porous metallic materials through controlled powder metallurgy and sintering processes.

The interconnected pore structure provides controlled filtration, stable gas or liquid flow, and high mechanical strength. Compared with conventional polymeric filter media, porous metal filters can provide better resistance to elevated temperatures, pressure, and demanding industrial environments.

We supply porous filters in titanium, stainless steel, bronze, nickel, and selected high-temperature alloys, with customized pore size, filtration rating, dimensions, and configuration.

Available product forms include round discs, sheets, tubes, and cylindrical filter cartridges.

Typical Applications

Porous metal filters can be used for:

Electrolytic gas filtration

Gas distribution

Ozone aeration

Water treatment

Odor-control and gas treatment systems

Reverse osmosis pre-filtration

Electronics and precision fluid systems

Chemical processing

Industrial gas and liquid filtration

Available Materials

Titanium Porous Filters

Titanium sintered porous materials combine low density, corrosion resistance, and mechanical strength. They are particularly suitable for applications involving seawater, selected chemical solutions, water treatment, gas distribution, and electrochemical processes.

Typical applications include:

Ozone aeration

Electrolytic gas filtration

Gas distribution

Water treatment

Reverse osmosis pre-filtration

Chemical filtration

Corrosive fluid filtration

Stainless Steel Porous Filters

Stainless steel porous filters offer a balance of mechanical strength, corrosion resistance, and cost efficiency.

Common materials include:

SS304

SS316L

Other stainless steel grades according to requirements

They are suitable for industrial water treatment, chemical processing, food and beverage processing, gas filtration, and general industrial filtration.

Bronze Porous Filters

Sintered bronze filters are commonly used for gas and liquid filtration, pneumatic systems, lubrication systems, and applications where good permeability is required.

Nickel Porous Filters

Nickel porous materials are suitable for selected high-temperature, chemical, and gas filtration applications where nickel-based corrosion resistance and thermal performance are required.

High-Temperature Alloy Porous Filters

Selected high-temperature alloys can be used for filtration applications involving elevated temperatures or demanding chemical environments.

Material selection should be based on the operating temperature, pressure, fluid composition, corrosion conditions, and required filtration performance.

Dimensions can be customized according to drawings, equipment configuration, and filtration requirements.

Filtration and Flow Performance

The porous metal structure consists of interconnected pores that allow gas or liquid to pass through while retaining particles according to the specified filtration rating.

The actual flow rate, pressure drop, and filtration efficiency depend on:

Pore size

Porosity

Filter thickness

Filter area

Fluid viscosity

Gas or liquid pressure

Operating temperature

Particle characteristics

For this reason, filtration performance should be evaluated according to the actual operating conditions rather than by pore size alone.

Chemical and Environmental Resistance

Porous titanium filters can be used in a range of corrosive environments when the material grade and operating conditions are properly selected.

Potential service environments include selected concentrations of:

Hydrochloric acid

Sulfuric acid

Nitric acid

Seawater

Sodium hydroxide

Carbonate solutions

Chloride-containing aqueous solutions

Important: Corrosion resistance depends on the specific material, concentration, temperature, aeration, impurities, and operating conditions. The chemical compatibility of each filter should therefore be confirmed before use.

Fuming nitric acid and highly aggressive mixed-acid environments require separate technical evaluation.

Titanium Sintered Porous Filter - Handling and Cleaning

To maintain filtration performance and prevent mechanical damage, the following handling recommendations should be followed.

Installation and Handling

During installation, removal, and cleaning:

Avoid scratches, impacts, and dropping the filter onto hard surfaces.

Install the filter in the correct flow direction.

Avoid sudden pressurization during operation.

Ensure that the filter is properly supported and sealed.

Cleaning

When the pressure drop increases or the flow rate decreases significantly, the filter should be cleaned according to the actual operating condition.

For suitable filter configurations, cleaning may include:

1. Back-blowing

Use clean gas to back-blow the filter. A typical cleaning procedure may consist of several short pulses.

2. Liquid Backwashing

After gas back-blowing, the filter can be backwashed with clean liquid where compatible with the filter material and process.

3. Offline Cleaning

If normal online back-blowing or backwashing does not restore the required flow performance, the filter may need to be removed for more thorough cleaning.

Cleaning pressure, duration, frequency, and cleaning medium should be determined according to the specific filter design and operating conditions.
