Abstract:
aquatic life struggles to survive. Hence, we can make use of the aeration process to make the water body from DO deficit to DO enriched.
Dissolved Oxygen (DO) is one of the prime indicators of water quality. For proper growth and survival of marine life, DO play a very important role. Out of these, aeration by diffusion has been found to be the most efficient method for the introduction of Oxygen and water. According to research carried out on different aerators, diffused aerators have been found to as the best and most efficient medium for aeration. Thus, by combining the benefits of diffused aeration and solar energy, solar diffused aerators can be designed which will efficiently enhance the DO level of water and will also promote green energy. Solar aerators even though beneficial are less popular in India. Thus, there is ample scope for the development of a diffused solar aerator which will enhance the DO of water and in turn will help marine life flourish.
The green revolution is taking momentum throughout the world. Thus, Promoting and using green energy is the need of the hour.
2.0 IMPORTANCE OF WORK: As the world is approaching the green energy revolution, it becomes necessary to replace the age-old expensive machines with new and practical ones. As the lakes and ponds are the places which receive uninterrupted sunlight throughout the day because of their open surface nature, the use of green energy will prove to be very efficient and effective. There is a need to change diesel aerators to a better and cheaper alternative so that marginalized fish farmers can benefit in a better way economically. The beauty of a lake gets tampered with all the turbidity and hyacinth in the lake, aerator is a machine which will prevent the growth of unwanted weeds and algae in the lake or reservoir. Aeration is a simple process with an easy-to-manage machine, it can be easily understood by the fish farmers and the nontechnical lake maintenance team. Solar Aerators can combine the benefits of Green Energy as well as aeration technology. Solar aerators have been popular in foreign countries. In India, solar aerators have been used in a few states but the technology is not yet fully developed or there is ample scope for further development. The most popular solar aerator in India is the 'paddle type surface aerator'. But according to research carried out by various researchers, diffused aeration is the most efficient type of aeration. If the diffuse aerator is combined with solar energy, the benefits can be multiplied. Thus, there is ample scope for the development of diffused solar aerators. Subsequently, after exhaustive research in solar aerators and aeration of water, it has been found that important work can be carried out on this topic.

1.0 INTRODUCTION: The Problem of pollution is increasing day by day, and the impact of the pollution produced by mankind is directly or indirectly imposed on the Flora and Fauna of the planet. All the polluted water from the industries and Domestic and municipal waste ends up in the lakes, reservoirs or streams of the city. This increases water pollution and reduces the Dissolved oxygen of the water body which has aquatic life in it. The Dissolved oxygen which had to be used by the aquatic life for their survival is used by the micro-organism (bacteria) present in the water body. Aeration is the process in which water and air are brought in close contact to remove dissolved gasses and oxidize dissolved metals, including iron, hydrogen sulphide and volatile organic matter. This process is typically the first major process at the drinking water treatment plant and occurs in the secondary treatment process of activated sludge treatment in wastewater treatment plants. An evenly distributed oxygen supply in an aeration system is essential to effective wastewater treatment for fostering microbial growth.
2.1 Objective: - To study the concept of Dissolved Oxygen and its importance to marine life.
By using the aeration process, we can ensure sufficient dissolved oxygen to the aquatic life of polluted water bodies. For the survival of the Aquatic animals, a minimum of 4mg/l or 4ppm is recommended. If the DO reduces below 4ppm the
