Demineralized Water | De-ionized Water | Zero TDS Water

High Purity Demineralized & De-ionized Water - Zero TDS

Demineralized water or de-ionized water is water that has had the majority of its mineral ions such as sodium, calcium, iron and copper removed. This process involves either ion exchange, reverse osmosis or distillation. By removing these impurities, process water attains high purity levels, making it essential for various industrial and scientific applications. Its fine solvent properties enable it to mix well with chemicals without adding unwanted ions, contributing to more uniform results in processes.

Demineralized water or De-ionized water is characterized by its conductivity which is lower than that of regular tap water, as the absence of salt reduces electrical conductivity. Manufacturers use high-purity water for laboratory experiments, in boiler and cooling systems to prevent scaling and in pharmaceutical production to maintain quality standards. The production techniques like reverse osmosis, allow the water to pass through multiple filtration stages, increasing its purity. Additionally, the use of high resistivity water across various sectors is supported by its adherence to strict quality control standards.
