Titanium Sintered Filter Cartridge for Lithium Extraction from Salt Lake Brine

Product Details

Core Product Features (Adapted to Salt Lake Brine Conditions)

Strong Corrosion Resistance: Resistant to high chlorine, high magnesium and high alkali brine, anti-pitting / crevice corrosion, no heavy metal dissolution, ensuring lithium liquor purity.

High Mechanical Strength: Integrally sintered without welding, resistant to high pressure and backwashing, not easy to deform / break, suitable for high brine flow rate and pulse cleaning.

High-Efficiency Depth Filtration: Curved micropores achieve over 99% retention efficiency, while allowing lithium salt ions to pass through, protecting rear-end lithium adsorbents / membrane elements from clogging.

Repeated Regeneration: Acid-base cleaning, steam backflushing and ultrasonic cleaning are available; flux recovery rate ≥95% after regeneration, service life 1–3 years (5–10 times that of PP filter cartridges).

No Secondary Pollution: Inert titanium material, no fiber shedding, no medium migration, meeting purity requirements of battery-grade lithium carbonate / lithium hydroxide.

Good Thermal Stability: Resistant to high-temperature brine and steam disinfection, suitable for high-temperature processes such as salt lake evaporation, concentration and lithium precipitation.

Application Scenarios for Lithium Extraction from Salt Lake Brine

Brine Pretreatment: Precision filtration of raw water to remove sediment, algae and colloid, protecting subsequent adsorption columns / membrane systems.

Adsorbent Protection Filtration: Security filtration before adsorption to retain tiny solids and prevent adsorbent bed clogging / caking.

Lithium Precipitation Mother Liquor Clarification: Remove lithium carbonate / lithium hydroxide precipitated fine powder to improve lithium recovery rate and product purity.

Lithium Liquor Refining: Terminal fine filtration to remove trace impurities, ensuring low iron, low aluminum and low silicon indicators of battery-grade lithium salts.

Special for High-Magnesium Brine: Tolerate high Mg²⁺, high Cl⁻ and high pH environment, no scaling or corrosion, stable long-term operation.

Selection and Installation Points

Accuracy Selection: Pretreatment 5–10 μm; Adsorption protection 1–3 μm; Refining 0.45–1 μm.

Size Matching: Select length (500–1000 mm) and outer diameter (Φ30/50 mm) according to treatment capacity, ensuring flux ≥0.5 m³/(m²・h).

Sealing Material: Fluororubber (FKM) for high-alkali brine; Metal graphite sealing for high-temperature conditions.

Installation Method: Vertical installation, outside-in flow; Regular (1–4 weeks) backwashing + acid cleaning regeneration to extend service life.

Comparison with Ordinary Filter Cartridges (Advantage Summary)

Corrosion Resistance: Titanium cartridge pH 1–14; PP / stainless steel cartridges are not resistant to high chlorine / high alkali, easy to corrode / dissolve.

Service Life: Titanium cartridge 1–3 years; PP cartridge 1–3 months, lower total cost.

Regenerability: Titanium cartridge can be repeatedly cleaned and regenerated; PP cartridge is disposable and non-renewable.

Temperature Adaptation: Titanium cartridge ≤280℃; PP cartridge ≤80℃, cannot be used for high-temperature brine.
