When it comes to protecting your drinking water in Bay of Plenty, filtration doesn\u2019t always mean removing sediment or chlorine. Sometimes, the concern is something you can\u2019t see at all \u2014 bacteria and microorganisms.<\/p>\n\n\n\n

That\u2019s where UV filtration comes in.<\/p>\n\n\n\n

What Is UV Filtration?<\/strong><\/p>\n\n\n\n

UV (ultraviolet) filtration is a water treatment method that uses ultraviolet light to disinfect water. It targets harmful microorganisms such as bacteria, viruses, and parasites, preventing them from reproducing and causing illness.<\/p>\n\n\n\n

Unlike chemical treatments, UV systems do not add anything to your water. Instead, they use light energy to neutralise biological contaminants as water passes through the system.<\/p>\n\n\n\n

How Does UV Water Treatment Work?<\/strong><\/p>\n\n\n\n

Inside a UV system, water flows past a specialised UV lamp. The ultraviolet light penetrates microorganisms and disrupts their DNA, effectively rendering them inactive.<\/p>\n\n\n\n

The process happens instantly and continuously while water is flowing. There\u2019s no change in taste, odour, or colour \u2014 just added protection.<\/p>\n\n\n\n
