4. Nutrient Additives In biological treatment processes, especially in activated sludge systems, the presence of nutrients, primarily nitrogen and phosphorus, is essential for microbial growth. Chemicals such as ammonium sulfate and phosphoric acid are sometimes added to maintain the required nutrient balance in environments where wastewater lacks sufficient levels.

4. Reduced Heat Sensitivity As a non-toxic and stable mineral, calcium carbonate is less sensitive to heat compared to many organic fillers. This stability makes it suitable for applications that require high processing temperatures, ensuring that the physical and chemical properties of the polymer remain intact.
