I. Introduction
Water canal treatment is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. First, we have an idea to use black carbon, filtration sand, rocks, and pebbles. The black carbon will help the canal water to remove the bad odor of the canal water. Filtration sand has three types: rapid sand filter, upflow sand filter, and slow sand filter. Slow sand filter is like the white sand that doesn’t need chemicals to produce high quality of water so we chose slow sand filter. Rocks and pebbles contain inorganic minerals that can dissolve sulfates and other chemicals of the canal water. We decided to do this process by layer to layer using bottles. We also used cotton cloth per layer and filter paper in the black carbon and filtration sand.

III. Data
TEST| RESULTS| INTERPRETATION|
A. INORGANIC MATTER TESTS| CANAL WATER| FILTEREDWATER| CANALWATER| FILTEREDWATER| 1. Chloride| absent| absent| Chlorine is absent in both canal water and filtered water. Other chemical including table salt is not present.| 2. Phosphate| present| present| It contains waste materials of humans or other living organisms.| The process is still not enough.| 3. Sulfate| present| present| Presence of shales or industrial wastes. It may be caused by the rain.| The process is still not enough.| B. PH...
