Liquid Caustic Soda 32% & 50% Solution for Industrial & Water Treatment Use

Key Advantages & Solution Performance

• Superior Low-Temperature Resistance & Zero Freeze Risks: Industrial caustic soda 32 provides outstanding resistance to crystallization compared to higher concentrations. With a freezing point around −5∘C, it eliminates solution freezing risks during outdoor storage and transport in sub-zero climates, drastically reducing energy demands for heat tracing lines and preventing emergency plant downtime caused by frozen transfer piping.

• Instant Processing & Lower Operational Expenditure: Utilizing caustic soda 32 completely eliminates the labor-intensive dissolution process, dedicated mixing tanks, and high electrical power needed when dissolving solid caustic soda. Ready-to-use liquid solutions enable immediate chemical reaction kinetics, reducing overall batch cycle times and significantly lowering operational expenditure across large-scale processing facilities.

• Enhanced Workplace Safety & Zero Airborne Dust: Utilizing liquid caustic soda 32 eliminates airborne dust hazards inherent to dry caustic flakes or beads. This pre-mixed liquid format dramatically improves workplace air quality, protects plant operators from respiratory exposure risks, and shields surrounding electrical cabinets, motors, and facility infrastructure from corrosive atmospheric damage.

• Exceptional Chemical Purity & Minimal Impurities: Formulated via modern membrane cell electrolysis, our caustic soda 32 maintains ultra-low iron, chloride, and chlorate impurity levels. This superior purity prevents unwanted insoluble precipitation, pipeline scaling, and pump valve clogging in automated liquid dosing setups, protecting downstream equipment and reducing plant maintenance downtime.

• Flexible Hazardous Transport Packaging: Supplied in heavy-duty UN-rated containers, including 1000L IBC totes, 200L polyethylene drums, and bulk ISO tank trucks. Each packaging type features robust corrosion-resistant barrier materials engineered to prevent leaks and atmospheric carbon dioxide (CO2​) contamination during transit and long-term storage.

Primary Industrial Applications

• Water & Wastewater Treatment: Functions as an economical pH adjustment reagent and alkalinity booster in municipal water facilities and industrial wastewater treatment plants. Caustic soda 32 enables continuous automated acidity neutralization while efficiently precipitating toxic heavy metal ions (Fe3+, Cu2+, Pb2+, Zn2+) into insoluble hydroxides for safe filtration and environmental compliance.

• Pulp & Paper Manufacturing: Essential in Kraft pulping processes for efficient wood chip digestion, lignin extraction, and pulp bleaching cycles. Caustic soda 32 helps break down cellular fibers while maintaining optimal cooking liquor alkalinity in large-scale paper manufacturing plants.

• Chemical Synthesis & Intermediate Production: Serves as a vital alkaline feedstock and foundational reaction catalyst in synthesizing a broad spectrum of organic and inorganic chemical compounds, including sodium salts, superabsorbent polymers, agricultural chemicals, and specialty surfactants.

• Soap & Liquid Detergent Processing: Primary saponification reagent required to efficiently convert fats, vegetable oils, and fatty acids into commercial liquid soaps, heavy-duty industrial degreasers, hard-surface cleaners, and specialized institutional sanitation products.

• Alumina Refining & Metallurgy: Extensively applied in the Bayer process, where concentrated caustic solutions digest bauxite ore under elevated temperatures and pressures to extract refined alumina (Al2​O3​). It is also widely used for metal surface etching, aluminum anodizing, and industrial equipment cleaning-in-place (CIP) operations.
