How Copper Sulfate Pentahydrate Is Used in Water Treatment: Practical Application Guide

Copper Sulfate Pentahydrate (五水硫酸铜(蓝矾)) is one of the most widely specified disinfection, sterilization & bleaching used across municipal and industrial facilities. As a blue vitriol / bluestone, it delivers reliable performance in the scenarios our customers ask about most: Water treatment, chemical agent, purified water, wood preservative, circuit board.

What Copper Sulfate Pentahydrate Is and How It Works

Copper Sulfate Pentahydrate is supplied as Blue crystalline powder. Its molecular formula is CuSO4·5H2O (CAS 7758-99-8). 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: Water treatment, chemical agent, purified water, wood preservative, circuit board. In practice this means blue vitriol / bluestone 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 disinfection, sterilization & bleaching programs.
• Logistics: available in 25/1000/1200kg woven bag with plastic lining, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Copper Sulfate Pentahydrate, buyers typically compare active content, packaging and the applicable standard (-). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Bromochlorohydantoin (BCDMH) to cover the full treatment chain from clarification to disinfection.
