Key Concepts

Reverse Osmosis Desalination

Reverse osmosis is a water purification process that uses a semipermeable membrane to remove impurities, including salts, from water. It is one of the most effective techniques for desalination, turning seawater into potable water.

Eutrophication

Eutrophication is the process where water bodies receive excess nutrients, such as phosphates, which stimulate dense plant growth and algal blooms. This process can lead to oxygen depletion in the water and harm aquatic ecosystems.

Sea Level Rise

Sea level rise refers to the increase in the average level of the world's oceans, primarily driven by the melting of ice caps and glaciers as well as thermal expansion of water as it warms. This phenomenon has significant implications for coastal regions.

Heavy Metal Contamination

Heavy metal contamination involves the introduction of toxic metals like lead, cadmium, and mercury into water supplies. These metals can have detrimental effects on human health and the environment even at low concentrations.
