Science of Water Filtration
Water goes on quite a journey to reach our taps, safe and ready to drink. One of many important steps in this process is ltration, which uses layers to sift contaminants out of the water. Edu-Toys introduces Water Filtration Kit telling kids how water gets cleaned by building a simple ltration system and more……
What’s Water Contamination?
Water contamination is the term used to describe hazardous materials of any kind that are polluting a source of water. This could include both biological and chemical substances, and the water source may be ponds, lakes, seas, oceans, or reservoirs used for drinking and bathing by humans. The most common types of water contamination are chemical runo from homes and businesses and sometimes human or animal waste materials. In industrialized nations, water contamination is much less common than in third world and developing countries. That’s because sophisticated water purication systems are in place to clean waste materials from the water, disinfect it using chemicals, and then purify it so that it is safe for consumption. Areas that do not have these technologies may encounter contaminated water due to animal wastes entering the water supply or household chemicals running from the ground into underground wells. Most sources of water contamination in the industrialized world come from chemical pollution, either from the dumping of chemicals onto the ground or down drains, or through accidental spills. Oil spills, for instance, may occur from wells or ships and can contaminate water for miles from the spill site. Industrial plants may also dump wastes into water, although this is less common due to tighter government regulations regarding disposing of hazardous materials. Any harmful material that enters water could be considered a form of water contamination. Drinking polluted water has been linked to gastrointestinal upset, the spread of certain illnesses, and sometimes death in severe cases.

What’s a Water Filtration System?
Whether water is drawn from a well or sprayed from a faucet, sometimes it is not t for human consumption. In some cases, it is even dangerous for many animals. A water ltration system can often solve this issue, as it separates contaminants in the water from the uid. There are many methods, but the goal of most of them is usually to lter harmful substances from water. One of the most common water ltration system types available uses carbon to lter contaminants. A carbon lter is particularly useful if a test indicates there are pesticides, chlorine, or other organic chemicals present in the water. This type of water ltration system is not helpful if there is chloroform, uoride, lead, or microbes. A water ltration system can be integrated into a plumbing line and is called a whole-house system. This will ensure that baths, showers, and both dishwasher and laundry cycles are as free of contaminants as faucets are. On the other hand, an approach that is usually less costly is to install only a faucet-mounted system. This kind often can be purchased at a local home improvement store and installed by the homeowner, but does usually require frequent lter changes. Consequences can result from unltered water. Some of the most harmful problems include impaired development, cancer, heart disease, gastrointestinal issues, and even death due to bacteria. Less serious issues range from constantly cloudy water to rust stains on appliances and clothes. Not only is ltered water generally better for people to drink, it usually tastes better as well. Many whole-house ltration systems are quite expensive, and though the kind that is connected to a faucet is typically cheaper, it still needs to be purchased and installed. There are other options, such as small ltered pitchers that can be lled with water from the faucet to be puried. Additionally, many newer refrigerators come equipped with their own ltration systems in the door so that some puried drinking water is available. Edu-Toys Water Filtration Kit provides the giant size do-it-yourself stacking containers with layers enabling kids to observe and experience how running water can be cleaned up to drinking water.
