The outer ring will act as a float device, keeping the system afloat

Openings at the top allow oxygen to diffuse to aerobic bacteria, while openings on the side allow warm water to flow out

The ceramic foam’s pores provide a large surface area for aerobic biofilm growth

The ceramic foam will physically trap dirt, sediments, and many other pathogens.

The biofilm, consisting of beneficial bacteria and microbes, will break down organic waste.

As warm water moves upward through the center, the cooler water from below and the sides will move in to replace it. This creates a convection current

The continuous contact between the flowing water and the biofilm layer slowly improves overall water quality

Even without sunlight, AquaFilter can still work as water is still moving passively through its ceramic foam by capillary action. Slight temperature differences in the water create small convection flows.
