Sodium hydroxide (NaOH), also known as caustic soda, is a chemical used in drinking water treatment processes, mainly for pH adjustment and the neutralization of acidic water. Its use must be supported by conformity certification, ensuring its quality, purity, and sanitary suitability for contact with water intended for human consumption.
Certification includes verification of the product’s chemical composition, compliance with limits for impurities and contaminants, and the suitability of its presentation, storage, and labeling in accordance with current regulations. Manufacturing conditions, transport, and product traceability are also evaluated to ensure it does not pose risks to public health.
Holding this certification is an essential requirement for the product to be used in drinking water treatment systems, providing assurance to drinking water plant operators, regulatory bodies, and end consumers.
