Calcium chloride water treatment agent is a chemical product widely used in the water treatment sector, primarily to remove impurities such as suspended solids and colloids, thereby improving water quality. Available in liquid form for easy transport and dosing, it contains 11% active ingredients and is suitable for various applications, including industrial circulating water systems and drinking water purification.
The primary component of this agent is calcium chloride (CaCl₂), which dissociates in water to release calcium ions (Ca²⁺) and chloride ions (Cl⁻). Calcium ions bind with anions such as carbonates and sulfates to form sparingly soluble precipitates (e.g., calcium carbonate, calcium sulfate), effectively reducing water hardness. Simultaneously, chloride ions destabilize colloidal particles, causing them to aggregate and settle. Additionally, the strong hygroscopic nature of calcium chloride helps regulate moisture balance and inhibit microbial growth.
As a liquid product, it can be dosed directly into the water without requiring a separate dissolution step. Dosage should be adjusted based on water quality parameters (such as turbidity and hardness), typically using metering pumps for precise control. Applications include industrial circulating cooling water systems (preventing scaling and corrosion), drinking water pretreatment (removing suspended solids), and wastewater treatment (aiding sedimentation and sludge dewatering). Care should be taken to avoid mixing it with strong oxidizing agents (such as sodium hypochlorite) to prevent the formation of harmful substances.
Compared to traditional flocculants, calcium chloride water treatment agents offer rapid dissolution and high reaction efficiency. Its liquid form minimizes the risk of dust pollution, aligning better with environmental protection standards. In industrial applications, the product significantly reduces the maintenance frequency of water treatment systems and extends equipment lifespan. In drinking water treatment, residual chloride ion concentrations comply with national hygiene standards, ensuring a high level of safety. Furthermore, adherence to national standards ensures consistent product quality, making it suitable for applications requiring strict water quality control.
Calcium chloride is a non-toxic inorganic salt widely used in sectors such as food processing and pharmaceuticals (e.g., for road de-icing and as a food desiccant). During the water treatment process, its decomposition products are calcium and chlorine; it does not introduce heavy metals or other harmful substances. Unreacted calcium chloride can be further removed through subsequent processes (such as reverse osmosis) to ensure the effluent meets quality standards. Long-term use has minimal environmental impact and aligns with sustainable development requirements.
