Talk:Biosand filter

Comment
Hello, I was reading this document and it sounds very interesting. However, I was wondering if anyone could point out the cons of biosand. It cant be all good, nothing is in this world. I want to know how it compares to traditional sand filtering. What are their differences and improvements over the other. If anyone could help, it'd be greatly appreciated.(Alkaroth (talk) 17:10, 12 March 2008 (UTC))
