Can water plant neutralise ammonia?

Ammonia is a colorless and pungent gas that is commonly found in both natural and man-made environments. It is a by-product of organic waste, animal excreta, and nitrogenous fertilizers. Ammonia can be toxic to aquatic organisms at high concentrations and can cause eutrophication, which is the excessive growth of algae and aquatic plants. However, aquatic plants have been known to play an important role in the removal of ammonia from water bodies. In this article, we will explore the process of ammonia removal by water plants and the effectiveness of this natural method.

How water plants remove ammonia

Water plants have a unique ability to absorb nutrients and pollutants from the water through their roots, stems, and leaves. One of the nutrients that water plants can remove is ammonia. When ammonia is present in the water, it is converted into ammonium ions (NH4+) by the plants. The ammonium ions are then taken up by the roots of the plants and used as a source of nitrogen for growth and development. In this way, water plants act as natural filters and help to reduce the level of ammonia in the water.

Factors affecting the effectiveness of water plants in removing ammonia

The ability of water plants to remove ammonia depends on several factors. Firstly, the type of plant and its growth rate play a significant role in the process. Fast-growing plants such as duckweed, water hyacinth, and water lettuce are more effective in removing ammonia due to their high nutrient uptake rate. Secondly, the concentration of ammonia in the water and the duration of exposure also affect the efficiency of the process. Water plants can remove ammonia more effectively at low concentrations and over a longer period. Thirdly, the water pH and temperature can also affect the absorption of ammonia by water plants. Most aquatic plants grow best in slightly acidic to neutral water with a temperature range between 20?C to 30?C.

Benefits of using water plants to remove ammonia

The use of water plants to remove ammonia has several benefits. Firstly, it is a natural and sustainable method that does not require any energy input or chemical treatment. Secondly, it is cost-effective and can be used in both small and large-scale applications. Thirdly, it has a positive impact on the environment by reducing the level of pollutants in the water and promoting the growth of aquatic life. Finally, it is a low maintenance method that requires minimal human intervention.

Limitations of using water plants to remove ammonia

While the use of water plants to remove ammonia has several advantages, it also has some limitations. Firstly, the effectiveness of the process depends on several factors as mentioned earlier. Secondly, it may not be effective in removing high concentrations of ammonia and may require the use of other methods such as aeration or chemical treatment. Thirdly, water plants may not be suitable for all types of water bodies and may require a specific range of conditions to grow and thrive.

The Bottom Line

The use of water plants to remove ammonia from water bodies is a natural and sustainable method that has several benefits. However, its effectiveness depends on several factors such as the type of plant, concentration of ammonia, and water quality. While it may not be suitable for all types of water bodies and may require other methods for high concentrations of ammonia, it is a low maintenance and cost-effective solution that has a positive impact on the environment.
