How to purify water with banana, apple and tomato peels in a natural way to reduce heavy metal and pesticide residues.
He is about to end up run over, his mother saves him
In recent years, some interesting studies have been carried out to identify gods alternative, natural and low-cost methods per purify the water.
Several international experts have developed some techniques that could allow purifying water with fruit, in particular with peels, citrus juice, rice husk or coconut fiber, to reduce the levels of pesticides, heavy metals, bacteria and toxic substances. Here are some examples.

Banana peels
Le banana peels they could be used up to 11 times to purify contaminated water from industrial plants and farms. One says so study conducted by River Water and published by the American Chemical Society which bears the title of "Banana Peel Applied to the Solid Phase Extraction of Copper and Lead from River Water". The reference is in particular to pollution from copper and lead. Experts point out the negligible cost of having banana peels available and the fact that there is no need to chemically treat them before starting the water purification process. Heavy metals, such as copper and lead, can pose risks to health and the environment. Banana peels contain substances such as nitrogen and other chemicals with negatively charged electrons that are able to bond with metals in water, which are usually positively charged. The experts they believe that the banana peel system to purify water can be developed also for domestic use.

Apple and tomato peels
Apple and tomato peels to purify the water. Researcher Ramakrishna Mallampati he initially experimented with this very economical method to facilitate the life of rural communities in developing countries. The peels would be able to absorb the harmful substances present in the water and could be used to make natural filters. The do-it-yourself method according to Mallampati's technique, it involves peeling apples and tomatoes and letting their skins soak in alcohol. Then the skins must be left to dry and dry. At this point you can place them in a container of water and wait for a couple of hours. So the water will be ready to drink. Ramakrishna Mallampati foundh and apple and tomato peels are capable of absorb toxic heavy metal ions, nanoparticles, preservatives and pesticides present in the water. The results of the experiments were published by the American Chemical Society. Click here to learn more and watch the video.
Coconut fiber and rice husk
In 1972, researchers worked on using a natural filter for water in Thailand to be obtained from coconut fiber and from rice husk, of the waste parts recoverable at no cost. Both would be able to eliminate unwanted residues and turbidity from the water, in order to purify it. These methods were tested without adding any additional chemicals. In particular, the rice husk showed high absorption capacity and improvement of the color, taste and odor of the water. See it study to know more.
Solar disinfection with citrus
It seems that water disinfection that involves combining sunlight and citrus fruits is capable of reduce E. coli levels and it seems that lime is the most effective fruit. One study recently published by the Johns Hopkins University School of Medicine found that add lime juice water makes the solar disinfection method faster. Preliminary results from this study show that the combination of citrus and sunlight could reduce the presence of E.coli in water in just 30 minutes and would only be needed. 30 ml of lime juice per 2 liters of water, a quantity that should not neither cost prohibitive nor cause an unpleasant taste.
