These are unicellular microalgae found in every aquatic habitat, soil, and waterway.
Diatoms are photosynthetic and have an outer shell arranged like a soap box composed of silica.
They are the primary producers of the ocean.
Many diatoms species live in freshwater including drinking water. Thereby acting as good indicators of water quality.
They are tiny microalgae present in every water source around the world and are mostly harmless to humans.
Drinking water consisting of diatoms does not usually result in any complications but it can be problematic when ingested in very large quantities or when contaminated with other microbes.
