ABSTRACT
The importance of Eco-Agriculture is getting more and more serious nowadays because of rapid world population growth. People need food to live. Energy and water are two essential inputs needed for every plant to grow and develop. Without energy and water no food can be produced. Energy and water resources are not evenly distributed on this planet. In some areas, like the Middle East and African countries, water is the limiting factor for producing food. At the same time, these countries have lots of energy re-sources in the form of sunshine. On the other side of the world the situation is totally different. In European countries, for example, water is not a problem. They have enough water resources but energy from sunlight is not always enough for plants to grow and produce food.
Producing food in a closed water system could be a good solution for Eastern countries with limited water resources. In a closed water recycling system, the water could be mechanically treated or filtered and reused. This system does no harm to the environ-ment or ground water resources. In this thesis, one of the most efficient water recycling systems, namely the Hydroponic method of growing plants, is introduced. This closed system does have some problems however, such as algal growth. Prevention of algal growth is one of the main topics of this work.
