In industrial water treatment, mining, and pulp and paper applications, precise pH control is fundamental for maintaining process efficiency, ensuring equipment longevity, and meeting environmental compliance standards. Traditional pH adjustment methods often present challenges related to handling safety, efficiency, and operational costs. To address these challenges, KGO Group has engineered an advanced Sodium Bicarbonate Dissolution System featuring vacuum-enhanced wetting, high shear mixing, and a flow-through design that optimizes dissolution efficiency—even in cold temperatures below 5°C.
The Advantages of Sodium Bicarbonate for pH Control
Sodium bicarbonate (NaHCO₃) is an increasingly preferred choice for pH control due to its unique combination of safety, efficiency, and environmental compatibility. Compared to traditional alternatives such as caustic soda (NaOH) or lime (Ca(OH)₂), sodium bicarbonate offers several key advantages:
- Safer Handling – Sodium bicarbonate is non-corrosive, reducing hazards for operators and preventing damage to storage and dosing equipment.
- Controlled pH Adjustment – Its gradual pH adjustment properties minimize sudden shifts, reducing the risk of process disruptions or damage to biological treatment systems.
- Reduced Scaling and Precipitation – Unlike lime, sodium bicarbonate helps prevent scale buildup in pipelines and tanks, decreasing maintenance requirements.
- Environmentally Friendly – As a naturally occurring compound, sodium bicarbonate is safe for discharge-sensitive applications and contributes to sustainable industrial practices.
Breakthroughs in Dissolution Technology
One of the key challenges in utilizing sodium bicarbonate for pH control is achieving effective dissolution, particularly in colder environments. KGO Group’s system is designed to dissolve sodium bicarbonate up to its maximum solubility of ~ 6 g per 100 mL of water at temperatures below 5°C. This is accomplished through a series of innovative engineering solutions:
- Vacuum-Enhanced Wetting – This feature accelerates hydration by ensuring uniform wetting of sodium bicarbonate particles, improving dissolution rates.
- High Shear Mixing – High-efficiency mixing technology breaks down solids efficiently, preventing undissolved material from accumulating and affecting process performance.
- Flow-Through Design—A streamlined flow system maintains continuous dissolution, reducing sedimentation risks and ensuring steady pH control.
- Automated Control Options – The system integrates seamlessly with industrial process monitoring systems, enabling real-time adjustments and precision dosing.
Extensive In-House Testing for Proven Performance
To validate the effectiveness of our dissolution system, KGO Group conducted extensive in-house testing to determine the optimal method for preparing a 6% sodium bicarbonate solution in cold water temperatures of approximately 4°C. Various mixing devices were evaluated to identify the most efficient approach, and dissolution times were carefully measured to ensure the complete solubility of the product under real-world conditions.
Additionally, we tested various types of mixers, sizes, and speeds to determine the most effective combination for achieving optimal dissolution. Through rigorous trials, we ensured that our system could consistently deliver superior performance in low-temperature environments, making it a reliable choice for industries requiring consistent pH control.
Enhancing Process Efficiency and Reliability
By integrating KGO Group’s advanced sodium bicarbonate dissolution technology, industrial operations can benefit from:
