High-Quality Desulphurized Heavy Calcium GCC from China Suppliers and Factory for Industrial Applications
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
QWhat is desulfurized heavy calcium carbonate and how is it produced?
Desulfurized heavy calcium carbonate (ground calcium carbonate) is produced by mechanically grinding high-purity natural limestone or calcite. The desulfurized grade is specifically processed to achieve high purity (≥92% CaCO₃), fine particle size (≤45 μm), and high brightness (≥95%), making it suitable for industrial and environmental applications.
QHow does desulfurized heavy calcium carbonate help in wastewater treatment?
Due to its weakly alkaline nature, desulfurized heavy calcium carbonate effectively neutralizes acidic substances in wastewater, raising the pH to stable and safe levels. It is widely used for treating acidic industrial wastewater, mine drainage, and other effluents to meet discharge or reuse standards.
QWhich heavy metal ions can be removed using desulfurized heavy calcium carbonate?
Desulfurized heavy calcium carbonate is effective in promoting the precipitation of a range of heavy metal ions from water, including lead (Pb), cadmium (Cd), and copper (Cu). By reducing their solubility, it significantly lowers their toxicity and environmental impact, with heavy metal content controlled to ≤0.005 W/%.
QCan the product specifications such as mesh size and packaging be customized?
Yes. Useen offers full OEM service, allowing customers to customize product mesh size, particle distribution, packaging format, and labeling to meet specific application requirements. This flexibility helps customers achieve cost optimization without paying for unnecessary features.
QWhat quality control measures are in place for desulfurized heavy calcium carbonate?
Useen operates its own large-scale mining resources and selects only top-grade raw materials. Quality is strictly controlled from the source through every stage of processing. Key parameters including CaCO₃ purity, brightness, moisture (≤0.5%), oil absorption value, and volatile matter are all tested and verified before shipment.
QWhat after-sales support does Useen provide for its products?
Useen provides a comprehensive and professional after-sales service system. The team responds quickly to customer inquiries and technical issues, ensuring worry-free product usage. Ongoing support includes technical guidance, product adjustment advice, and timely resolution of any quality concerns to build long-term customer trust.
