Question

Does Electrolysis purify Water?

Answer 1

Hint: When electric energy is applied, water in its liquid state is broken down into its component parts, hydrogen and oxygen. Different electrolysis procedures have evolved over time because the temperature and pH of the water affect the electrical currents that pass through it when electrodes are introduced.

Wastewater Purification Using Electrolysis:
In the world of large-scale water filtration, electrolysis has turned into a viable option and is currently being tried on sewage and flood water. This method divides hydrogen and oxygen gas, eliminating microorganisms simultaneously, using the same scientific principle as water purification tablets. It produces solid waste, pure water, hydrogen, oxygen, and other byproducts that can be safely disposed of. Some scientists even think that, should the technique become more extensively employed, the hydrogen produced during this process could be used as fuel.

Other applications for electrolysis as a water treatment technology are also possible. Some scientists are optimistic that it will be able to handle floodwater. In places like Bangladesh, where it's not uncommon for months to pass without a regular supply of clean water, this might literally save lives. The anticipation about this technology's potential has even inspired some households to construct their own electrolysis purifying systems.

Electrolysis, UV radiation, and membranes have all demonstrated potential as efficient water filtration methods. And they will undoubtedly get better as long as this field of study is researched. Reverse osmosis or UV light systems are the only options available to households right now for their water problems.

Note: Typically, the electrolyte for water electrolysis is an aqueous solution of caustic potash or soda. At equal concentrations, caustic potash solution has a higher conductivity than caustic soda solution. Both caustic potash solution and caustic soda solution have reduced carbon dioxide solubility, which contaminates the electrolyte and reduces its conductivity.
