It occupies two thirds of the Earth's surface, accounting for 60% of the adult body, including 75% of our brains! Every day we need to consume more than 2 liters - the liquid we drink and the food we eat. There are lots of H2O in the surroundings, but most of them can not be accessed or understood by people. But with water treatment, we can purify the water and get the necessary water.
Note: Adult supervision is necessary when handling chemicals and cuttings. Do not forget to use proper safety equipment when testing
Lid and shake vigorously for 30 seconds. Then pour about ten times back and forth between the two cups
Add 2 tablespoons alum to the water in the bottle and cut it at the top. Stir the water slowly with a spoon for 5 minutes. When you stirred the water, what did you notice?
Stay water for 20 minutes, check every 5 minutes, pay attention to its appearance and smell (please do not move).
Please fix the filter paper in the mouth of the bottle and use the rubber band to cut it at the bottom. Pour into a beaker
Pour pebbles into the bottle. Then pour coarse sand over the pebbles and pour fine sand onto the coarse sand.
Carefully pour 2 liters of clean tap water carefully so as not to disturb the upper sand. Pour the rinse water into the beaker
Pour 2/3 of the upper half of the moist water into the filter, taking care that deposits will remain in the moist water bottle.
When all the water passes through the filter, the marsh water and the filtered water are compared. What is the difference between appearance and smell?
There are five steps in basic water purification. Aeration, coagulation, settling, filtration, and disinfection. Our project led us through the first four projects. Aeration increases air. It makes it possible to escape capture of underwater gas and add oxygen to water. Is coagulation a process that makes it possible to chemically "cling" soils and other suspended solid particles? Enter flock (alum and sediment chunks). In this process, water is also purified or purified to be colorless. Precipitation is the process that occurs when gravity attracts floc particles to the bottom of the container. Therefore, if the water is not disturbed, most flocs will settle and prepare for the water of the next step. Filtration is the process of separating and removing the remaining solid particles and floating matter from the water. Disinfection is the last step to chemically treat water to remove bacteria and other microorganisms. These invisible bacteria can cause serious illness or even death.
Purified water refers to various techniques for removing dirt, trash, chemical residues from water. This is a topic that is easily integrated into science fair projects, experiments, classroom activities. Students can gain practical experience through various projects that can adapt to each grade and observe scientific behavior. Students do a series of experiments and decide on the best way to filter the water. At first, the students mixed sand and mud with water to make a sample of dirty water. Then the kids try a variety of different materials (eg coffee filters, paper towels, old T - shirts and toilet paper). Students pour dirty water through the filter into the glass and identify which filter is most effective by identifying the cleanest water sample. You can also compare experiments using various natural materials such as sand, charcoal, gravel, wood chips as a filter.
Environmental Science and Water Purification Environmental science is a scientific field that includes the foundation of biology and physics, and how people and animals in animals respond to environmental and habitat, problems they face or they are facing I will study the problem and how it works. There are similar fields such as environmental engineering, and the themes of design and technology are also increasing. Water purification is a process involving the acquisition of bacteria and unpleasant substances that can impair the purity of water. Pollutants invade the water from natural disasters, leak into the water system, and even waste on our lakes and rivers. Water purification is a necessary thing to survive and should not decide whether to relax. Water purification is an artificial process that makes our water safer. There are three types of water in environmental organizations
