Caustic Soda Dissolving System
We offer a fully integrated Caustic Soda Dissolving System designed for the safe, efficient, and cost-effective preparation of sodium hydroxide (NaOH) solutions directly at your plant. This system is ideal for industries with high or variable consumption of caustic soda, or in locations where the reliable supply of liquid caustic soda is limited.
Our system produces caustic solution by dissolving solid caustic soda (flakes, pellets, beads, or powder) in water under controlled conditions. The dissolution process is exothermic, generating temperatures up to 95°C, which is carefully managed through engineered safety and cooling features.
Our system is ideal for a wide range of industries including water treatment, chemical processing, pulp & paper, and manufacturing plants requiring reliable NaOH preparation.

Frequently Asked Questions
A Caustic Soda Dissolving System is an automated process unit designed to dissolve solid sodium hydroxide (NaOH), such as flakes, pearls, or pellets, into a controlled concentration of liquid caustic soda solution. The system provides safe, reliable, and efficient on-site preparation of caustic soda for industrial applications.
A Caustic Soda Dissolving System allows plants to produce sodium hydroxide solution directly on-site, reducing dependence on liquid caustic soda supply, lowering storage requirements, improving operational flexibility, and ensuring consistent solution quality.
The system automatically feeds solid caustic soda into a dissolving tank where it is mixed with water under controlled conditions. An agitator ensures uniform dissolution, while temperature monitoring and control manage the heat generated during the highly exothermic dissolution reaction.
A Caustic Soda Dissolving System can typically produce sodium hydroxide solutions with concentrations ranging from approximately 20% to 50% NaOH, depending on process requirements and application needs.
Key benefits include safe chemical handling, consistent NaOH concentration, reduced chemical transportation requirements, lower operating costs, automated operation, and improved process reliability.
Caustic Soda Dissolving Systems are widely used in industries such as chlor-alkali, chemical processing, water treatment, food processing, pulp and paper, mining, and industrial cleaning applications where reliable sodium hydroxide supply is required.
A Caustic Soda Dissolving System minimizes direct operator contact with solid caustic soda by using enclosed feeding, automated dosing, controlled mixing, and safety features designed to reduce exposure to corrosive chemicals and high-temperature solutions.
Yes. The system can be equipped with automated sack unloading or bulk bag discharge options to safely transfer solid caustic soda into the dissolving process while reducing manual handling requirements.
To properly size a Caustic Soda Dissolving System, important information includes required NaOH concentration, production capacity, raw material form (flakes, pearls, or pellets), water quality, operating temperature, storage requirements, and plant layout.
