How To Reduce TDS in Water

Certain water treatment systems serve as effective solutions for reducing or eliminating TDS from water, particularly when levels reach 500 ppm or above. While various filtration methods can be applied depending on the composition of TDS, reverse osmosis systems, water distillers, and deionization units are among the most comprehensive options, capable of removing the majority of dissolved solids.

Reverse osmosis

A reverse osmosis (RO) system ranks among the most thorough methods for contaminant removal. It operates by applying pressure to force untreated water through a semipermeable membrane. This membrane contains microscopic pores that trap pollutants like total dissolved solids, while permitting purified water to pass through.

Water distillation

Distillation is a water purification process that replicates the natural atmospheric cycle of evaporation. Water distillers heat water into steam, leaving behind total dissolved solids and other contaminants, which are unable to vaporize. When the steam condenses back into liquid form, the result is purified, contaminant-free water.

Deionization

Deionization systems eliminate total dissolved solids via an ion exchange process, utilizing specially formulated resins that alter the electrical charge of ions. Water ions displace charged ions from dissolved solids, resulting in water of very high purity. As a result, deionization cartridges are commonly known as high-purity filters.
