Hyundai, like other automakers, requires high-purity water for paint preparation and car painting. To reduce water consumption, they treat and reuse wastewater while ensuring it meets strict chemical and microbiological standards. Maintaining water quality is crucial for Hyundai’s 10-year paint warranty, as it prevents microbial contamination during production. The Colifast ALARM instrument is used to monitor treated water for reuse, ensuring it remains free from harmful microorganisms.
