Welcome to Changshu Hongyu Calcium Co., Ltd.
Product: Calcium Hydroxide
Our calcium hydroxide product offers two efficient methods of use:
- For dry method application, the equipment required is simple. However, the reaction may be slow with lower utilization rates.
- When using the wet method, our calcium hydroxide is formulated into a lime emulsion with a mass fraction of 5%-10%. This emulsion ensures a rapid reaction, typically stirred for 5-20 minutes.
Handling abnormal situations:
- Adjust dosage promptly if influent pH levels fluctuate significantly.
- Dilute the calcium hydroxide emulsion after adding for easy mixing and reaction.
- Promptly separate and remove any sludge generated during the neutralization process.
