How Calcium Chloride Is Used in Water Treatment: Practical Application Guide

Calcium Chloride (氯化钙) is one of the most widely specified water plant auxiliary chemicals used across municipal and industrial facilities. As a CaCl2 desiccant, it delivers reliable performance in the scenarios our customers ask about most: Excellent flocculant in environmental protection and water treatment; snow melting, deicing, multipurpose desiccant.

What Calcium Chloride Is and How It Works

Calcium Chloride is supplied as White flake, powder, granules, pellet. Its molecular formula is CaCl2·2H2O / CaCl2 (CAS 10035-04-8 (dihydrate) / 10043-52-4 (anhydrous)). Because of this physical form it dissolves and disperses predictably, which makes dosing and process control straightforward for plant operators.

Primary Applications

Its key application areas include: Excellent flocculant in environmental protection and water treatment; snow melting, deicing, multipurpose desiccant. In practice this means CaCl2 desiccant is selected for both routine maintenance and shock-treatment programs, depending on the water matrix and treatment goal.

• Process reliability: stable active content and consistent granule/tablet size improve dosing accuracy.
• Compatibility: works within existing dosing and storage setups common to water plant auxiliary chemicals programs.
• Logistics: available in 25/1000kg woven bags with PE liner, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Calcium Chloride, buyers typically compare active content, packaging and the applicable standard (GB/T26520-2011). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Sodium Hydroxide (Caustic Soda) to cover the full treatment chain from clarification to disinfection.
