Limiting Nutrients

Limiting Nutrients Diatoms are tiny, unicellular algae found in both freshwater and saltwater environments. They play a vital role in aquatic ecosystems as they are the foundation of the food chain. However, when conditions are favorable for their growth, they can multiply rapidly, leading to a phenomenon known as a diatom bloom.

Such blooms can be problematic as they deplete oxygen levels in the water and can lead to the death of fish and other aquatic organisms. Nevertheless, preventing diatom blooms is possible by limiting certain nutrients. Diatoms require nutrients such as nitrogen and phosphorus to grow, so cutting down on the amount of these nutrients in the water can prevent their proliferation.

Fertilizers, sewage, and other human activities typically discharge high levels of nitrogen and phosphorus into water sources. Therefore, regulations need to be put in place to limit the amount of these nutrients released into the water. In doing so, it will be possible to reduce the incidence of diatom blooms and safeguard aquatic life.

Treatment of Diatom Bloom
