Representative values shown. Choose grade by handling (bulk
density/flow) and application needs. Run dose trials to hit target
alkalinity without overshooting pH setpoints.

• Water treatment pH/alkalinity adjustment; acid
neutralization; buffering for coagulation; scrubber
alkalinity; pulp & paper; detergents; glass manufacture;
chemical synthesis. • Typical pH control dosing based on alkalinity gap and flow—pilot to optimize and avoid overshoot. |
• 25 kg bags • 50 kg bags • 1 MT big bags • Bulk
(rail/road). • Solution: 1000 L IBC • bulk tanker. |
• Non‑DG. Keep dry, sealed, and off the floor; avoid moisture/CO₂ pickup (caking). Use dust control and PPE; solutions are strongly alkaline—avoid contact with acids and aluminum in confined systems. Clean spills dry to prevent slippery floors. |
