The study of biochemistry cannot be completed without the acknowledgement of water, also termed the ‘elixir of life.’ Nevertheless, due to an increase in pollution levels in recent years, water quality has been significantly impacted. Some of the most affected organisms by water contamination are fragile marine organisms, including corals. ETPs are found to be a critical solution in protecting these important ecosystems and have a significant role in minimising pollution, maintaining biodiversity, and ensuring the sustainability of coral life.
The Function of Coral Reefs in the Sea Environment
Some of the richest ecosystems on earth are coral reefs, often referred to as the ‘rainforests of the sea.’ These underwater structures also provide habitat for many types of marine life, control coastal temperatures, and serve as natural barriers against storms and storm surges. But they are rather vulnerable to environmental fluctuations, especially water pollution.
Civilisation contributes to industrial waste, untreated sewage, and agriculture leads to water pollution, and oil spills contribute to eutrophication. This results in the formation of algal blooms, the reduction in oxygen, and the prohibition of light on the corals, leading to coral bleaching and death, respectively. Coral reefs are thus an endangered ecosystem that requires protection worldwide.
Understanding Effluent Treatment Plants (ETPs)
Effluent treatment plants are specialised systems designed to treat wastewater generated by industries before it is released into the environment. By employing advanced technologies, ETPs remove harmful contaminants, ensuring water discharged meets environmental safety standards. These systems are part and parcel of the wastewater treatment process, which uses physical, chemical, and biological means to remove pollutants, including:
Heavy Metals: Toxicants of industrial processes that contaminate aquatic environments.
Organic Compounds: Decomposable substances that cause oxygen depletion.
Chemical Pollutants: Toxicants that interfere with marine life.
Oils and Grease: Oils and grease are non-biodegradable pollutants that smother aquatic life.
How ETPs Safeguard Coral Reefs
1. Reducing Pollution in the Oceans
ETPs serve as the first line of defence against industrial pollution. They help to decrease the amount of dangerous materials that enter the sea by filtering out dangerous impurities from wastewater. This acts to support the water quality that is suitable for supporting coral reefs’ survival.
2. Controlling Algal Blooms
High-level nutrients in the water resources, mainly nitrogen and phosphorus derived from the industries, eliminate the unnecessary growth of algae. These algal blooms inhibit light penetration when light is important in the photosynthesis process of zooxanthellae, microscopic algae, which feed corals and give them their colours. ETPs help to overcome this problem by treating wastewater and preventing nutrient overload.
3. Measures for Reducing the Impact of Acid Rain
Acid rain is caused by air pollution and, in turn, pollutes water bodies as well. ETPs treat industrial effluents and remove factors such as sulfur and nitrogen oxides, which are responsible for acid rain that, in turn, affects coral reefs.
4. Coral Reefs and the Challenge of Increasing Ocean Temperatures
The absence of pollutants in water enables the coral reefs to cope with the impacts of climate change, such as high water temperatures. Reclaimed water reduces fluctuations in conditions that corals need for survival; they fuel paradigms of a consistent ocean.
ETPs and Coral Reef Restoration
Effluent treatment plants have demonstrated considerable effectiveness in regions where industrial pollution threatens marine life. Similarly, ETP installation in relevant polluted territories greatly contributed to the decrease of algal blooms and the overall improvement of the state of the coral. These systems have not only restored water quality but also revived the marine life around these systems, making them of principal importance in conservation.
