The Ca-alginate beads were able to remove all the heavy metals from the water at different degrees. Also, a prototype filter using the Ca-alginate beads was constructed and successfully tested.<\/p>\r\n<div class=\"clear\"><\/div>\r\n<div class=\"add-10px-space\"><\/div>\r\n<p> BiographyMy name is Ossama Mahmoud, I am in grade 9 and go to the Al-taqwa Islamic School. I really enjoy science and math. I got inspired to do this project because I wanted to find out how clean the water is in London, especially that one of the biggest water polutants are heavy metals. I did some research and found out that I can use certain types of plants to clean water. My favorite sport is Judo, I am a blue belt and enjoy competing at high levels. This is my second year in the Canada wide science fair. In the future I would like to be a physician.<\/p>","_et_gb_content_width":"","footnotes":""},"class_list":["post-7397","page","type-page","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 5.0.1.1 - aioseo.com -->\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<link rel=\"canonical\" href=\"https:\/\/tvsef.ca\/?page_id=7397\" \/>\n\t<meta name=\"generator\" content=\"All in One SEO Pro (AIOSEO) 5.0.1.1\" \/>\n\t\t<meta property=\"og:locale\" content=\"en_US\" \/>\n\t\t<meta property=\"og:site_name\" content=\"Youth Science London\/Thames Valley Science &amp; Engineering Fair - Grade 4-12 Science Engineering Fair.
