Desulphurized Heavy Calcium GCC - Top China Suppliers Factory for Power Plant Desulfurization and Water Treatment
Product Description
Neutralizing acidity in wastewater treatment, adjusting pH and stabilizing water quality.
Useen desulfurized heavy calcium carbonate is weakly alkaline and can neutralize acidic substances in water treatment, increasing the pH value of the water. It is particularly suitable for treating acidic wastewater, mine wastewater, and industrial wastewater, helping to stabilize water quality and meet discharge or reuse requirements.
Promoting the precipitation of heavy metal ions in water, reducing their toxicity.
Desulfurized heavy calcium carbonate can promote the precipitation of heavy metal ions (such as lead, cadmium, and copper) in water, thereby reducing their solubility and toxicity, improving water safety, and minimizing harm to the environment and living organisms.

Frequently Asked Questions
Q
What is desulfurized heavy calcium carbonate and how is it produced?
Desulfurized heavy calcium carbonate (ground calcium carbonate) is a finely ground natural calcium carbonate mineral. It is produced by mechanically grinding high-purity limestone or calcite ore, resulting in a white powder with a high CaCO₃ content of ≥92%. The "desulfurized" grade is specifically processed for use in flue gas desulfurization and water treatment applications.
Q
What is the pH range of desulfurized heavy calcium carbonate, and why does it matter?
The pH value of desulfurized heavy calcium carbonate is between 8 and 10, making it weakly alkaline. This property is essential for neutralizing acidic wastewater, adjusting water pH to safe and compliant levels, and stabilizing water quality in industrial and municipal water treatment processes.
Q
How does desulfurized heavy calcium carbonate help remove heavy metals from water?
When added to water containing heavy metal ions such as lead (Pb), cadmium (Cd), or copper (Cu), desulfurized heavy calcium carbonate raises the pH and promotes the formation of insoluble metal hydroxides and carbonates. These precipitates can then be easily removed by sedimentation or filtration, significantly reducing heavy metal concentrations and toxicity in the treated water.
Q
Can the product specifications such as mesh size and packaging be customized?
Yes. Useen offers full OEM and customization services. Customers can specify mesh size, average particle size, packaging format, and labeling requirements. The professional R&D team will conduct targeted optimization to ensure the product parameters precisely match your application needs.
Q
What quality certifications and raw material standards does Useen's desulfurized heavy calcium carbonate meet?
Useen sources raw materials from its own large-scale green mining base, ensuring strict quality control from the source. Key quality indicators include CaCO₃ ≥92%, brightness ≥95%, moisture ≤0.5%, and heavy metal content (as Pb) ≤0.005%, meeting the stringent requirements of industrial water treatment, environmental protection, and other high-end applications.
Q
What after-sales support does Useen provide for its desulfurized heavy calcium carbonate products?
Useen provides a comprehensive after-sales service system, including timely technical support, product application guidance, and rapid response to customer inquiries or issues. The company is committed to ensuring worry-free use of its products and building long-term partnerships based on trust and customer satisfaction.
