As population grows‚ drinking water becomes one of the most valuable resources in the world nowadays. The drinking water even becomes an important public health issue in some developing countries such as China and some African countries. During the entire process of drinking water treatment‚ the step of sterilization is especially important. The reason is that the raw water contains many kinds of microbes‚ which may results in spread of infectious diseases. This paper will show some sterilization

process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis provides the base for the one way flow of energy through the biosphere. Plants convert energy from the sun into sugars‚ which provide fuel for themselves and for other organisms. Photosynthesis also cycles carbon and oxygen nutrients through the biosphere. Producers are organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic

classrooms but was then applied to surrounding communities. According to Diaz‚ the technology is as simple as it could be. Each bottle contains water and bleach. When placed into a purpose-built hole in the roof‚ the homemade bulb refracts and spreads sunlight‚ illuminating the room beneath. Today‚ the project has expanded to more than 15‚000 solar bottle bulbs in 20 cities and provinces‚ benefiting more than 200‚000 families. It aims to reach 1 million beneficiaries by 2012.

temperature of about 100oC for a short period of time. Water heated to temperatures below 100C is generally referred to as pasteurized water. * Solar ultraviolet water disinfection‚ known as SODIS‚ is a method of disinfecting water using only sunlight and plastic bottles (PET bottles). This is an effective and very cheap method. SODIS is usually applied at the household level. Due to the fact that it is an affective and cheap method it is applied in numerous developing countries. Within Africa

is significantly higher in the grassland than inside the forest. The causes of variation are mostly due to their difference in biotic components present. Forests have tall trees and layers of canopy that can intercept both sunlight and wind. Due to the blockage of sunlight by ____‚ the forest’s interior received only 26.18 lux while the grassland received 1028.7 lux. The colder air and soil temperature of the grassland can be attributed to the rainy weather condition at the date and time of

reduces the amount of greenhouse gases‚ because people walk instead. In the Sister Solariums‚ each of the building’s floors are fanned out into a spiral during the day so that each floor gets equal amounts of sunlight. Solar-powered LEDs provide light during bad weather and at night for extra sunlight. The risk of environmental factors affecting the food is greatly reduced because it is all grown completely indoors to reduce the risk of poor air quality and pests. Also‚ there are multiple locations for

will happen because the plant will have enough carbon dioxide and water to keep up with the amount of light that there is. When there is less light intensity‚ photosynthesis will happen at a slower rate because gradually there will not be enough sunlight as there is carbon dioxide and water.
