2. Forming/Compaction

Titanium powder is compacted into a ‘green’ body using processes like uniaxial pressing, isostatic pressing, or slip casting. This shapes the disc and dictates initial density.

3. Sintering

The green body is heated in a vacuum or inert atmosphere (e.g., argon) to a temperature below titanium’s melting point. This causes particle bonding and neck growth, forming the final porous structure.

4. Post-Processing

Includes sizing, annealing, and surface treatments (e.g., acid pickling) to achieve precise dimensions, improve mechanical properties, and ensure cleanliness.

5. Quality Control & Testing

Each sinter titanium disc undergoes rigorous testing for pore size distribution, permeability, bubble point, mechanical strength, and material purity (e.g., using SEM, mercury porosimetry). Adherence to ISO, ASTM, and ANSI standards is ensured.

Case Study 1: Enhanced Catalyst Recovery in Petrochemical Processing

A major petrochemical plant faced significant challenges with catalyst fines loss and frequent shutdowns due to the failure of conventional ceramic filters. The highly corrosive nature of the process stream (containing hot sulfuric acid and hydrocarbons) degraded existing filters rapidly, leading to high operational costs and environmental concerns.

Solution: The plant collaborated with a specialized manufacturer to implement custom-designed sinter titanium disc filters. These discs were engineered with a specific pore size (5 µm) and enhanced mechanical strength to withstand the high-temperature and corrosive environment.

Outcome: After deployment, the titanium filters demonstrated superior performance. Catalyst recovery efficiency increased by 15%, translating to millions in annual savings. Filter service life extended from 6 months to over 2 years, drastically reducing maintenance downtime and associated labor costs. The enhanced corrosion resistance of the sintered titanium eliminated the issue of filter degradation, ensuring consistent product purity and environmental compliance. This experience confirmed the long-term economic and operational advantages of investing in high-quality titanium filtration solutions.

Case Study 2: Pre-filtration for Reverse Osmosis in Seawater Desalination

A large-scale seawater desalination facility struggled with persistent fouling of its Reverse Osmosis (RO) membranes. Despite multi-stage pre-treatment, fine particulates and biological growth frequently clogged the membranes, necessitating intensive chemical cleaning and premature membrane replacement.

Solution: The facility integrated a bank of `titanium filter disk` elements as the final pre-filtration stage before the RO membranes. These discs, selected for their precise 1 µm pore size and exceptional resistance to seawater corrosion and biofouling, provided a robust barrier against remaining particulates.

Outcome: The implementation of the sinter titanium disc system led to a significant improvement in RO membrane performance. Membrane cleaning frequency was reduced by 40%, and the average lifespan of the RO membranes increased by over 18 months. The bio-inert nature of the titanium also mitigated biological fouling, contributing to more stable operation and reduced operational costs.
