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))[reply]
TivaWater is the newest version of the plastic biosand filter and has several important improvements. Source: tivawater.com 187.253.122.140 (talk) 04:33, 28 May 2022 (UTC)[reply]
