@ecofran is making waves on TikTok by showcasing a behind-the-scenes look at a cruise ship’s wastewater treatment system. This innovative setup ensures that the ship's wastewater meets some of the strictest standards in the world, specifically those of the Baltic Sea regulations.

In her latest video, @ecofran dives into the fascinating process that keeps the cruise ship’s wastewater clean and compliant. It all starts with a pre-filter that tackles larger debris and items. From there, the water flows into mixing tanks before moving to the bioreactor, where microorganisms break down organic matter.

Next up is the flocculation unit, where solids are removed through a coagulation process. The water then undergoes flotation in a specialized basin to separate any remaining particles. A polishing filter ensures that any lingering particulates and bacteria are removed, and finally, UV lights provide an extra layer of disinfection.

Watch the video for a glimpse into the complex world of wastewater treatment aboard cruise ships, and see how cutting-edge technology and strict regulations come together to keep our seas pristine.
