Chapter 1 Origin and importance.In this current The population of the world increases the amount of resources, but a few long, not enough resources, the demand for forest resources, whether mineral. Fuel, food and water, especially the water, which is important for all kinds of creatures on Earth. Whether they are used in moderation or literally, we would do? If one day there is not enough water needs; Thus was born the idea for waste water treatment in order to bring it back. We define a water bath is used for treatment, according to the international situation, work came to a concert by concert held in three days. Have the participants number of 10000 people concert by concert attendees are required to shower, which number it is no longer sufficient demand, thus causing the water treatment system to bring bath back again. So enough of the concert attendees. The water treatment process is that we are sending water to the filter step to filter impurities that are larger, such as the hair, then sent to the various filters to filter out impurities, dirt, odour and bacteria which bacteria it cannot filter Organization.Ongphiang only need to use the method of killing bacteria with air to kill bacteria. Then send the water to fill the water tank for chlorine to make water more cleaning, and the most important part for another part of the system is to measure water quality, and the importance of measuring quality is the quality of the water that, in order to have a clean enough or safe products.Yato who specialize or not. If there is not enough clean water or chemicals with bacteria, dirt, may be affecting those who consume it. Therefore, in this situation the concept to apply in future water resources may not be sufficient demand. Using the method of water treatment.Aim.To save resources by bringing the sewage treatment and come back so that sufficient demand for water.To check the water quality measures in order to achieve maximum security (literally).Definition of termsWaste waterDay treatment.Water qualityThe scope of the study. The basic theory of matter, water and waste water. Waste water treatment process The quality of the water and the water used to bathe and then to compare water quality both before and after the treatment that are different? In order to get a high quality water supply is safe. Create a water quality measurement systems and sensors of the micro Explorer Contoso measuring color and light to measure turbidity of the water.The benefits expected to be received. Can water treatment that uses and then used again. To save water resources. The quality of the water, which can be monitored are very important. In order to bring the water.
