                                                (บทคัดย่อภาษาอังกฤษ)






               Mein objective of this project is to fix the water in roong-aroon school and people can use
               it.We have the way to operate as follow first we research topic about our project then we ask

               the knowledgeable too after that we build this water purifier and then we test it. By collecting
               information from  different things first is the color of the water second is the smell of the

               water third the pH of the water forth is the DO of the water fifth is the temperature of the
               water and the last one is turbidity value-clear of the water. Work modification process is in

               plan one we did not have much time, so we change to plan two but plan two were too similar
               to water purifier that we make in term one, so we change again to plan three it just plans one

               but easier to make.
                                   The results of the study and project preparation found that the water

               had no color but still has foreign matter and the smell is smell like it still has foreign matter
               too. The oxygen value is at level that something can potable, and the pH is on form a middle
               to alkaline.

               The temperature is on average. In conclusion, it can be that potable water that can washing
               rags.
