Does this rapid sand filter also remove or inactivate viruses, E coli, cholera, salmonella and other harmful pathogens? Professor Amburgey; how does this help "millions of people in developing countries" more advantageously than biological slow sand filters? Would these filters be small filters used by individual families, or large corporate projects costing billions of dollars to construct? Where are individual families going to get ferric chloride, and do they know how to handle toxic chemicals? How are these filters cleaned? Are they sustainable technology - in other words do they need petroleum derived energy, and produce no toxic byproducts? Why would an individual family need 30 to 50 times as much water as can be produced by a slow sand filter? What about the millions of people who carry water in buckets to pour into their filters - can they carry 30 to 50 times more water? Your project sounds technically very cool, but not practical for developing countries, and environmentally unsustainable as it depends on toxic chemicals which require large amounts of energy to produce and which must be added to the system. The biosand filter, developed by Dr. Manz, is already doing a fine job purifying water and empowering local cultures in developing countries without making them dependent on chemical companies and corporate greed. As we now are experiencing, corporate greed brings on catastrophic results. How is your product better for people in developing countries? I challenge you to answer. Interesting.

Dr. Amburgey has got a novel idea there. I just hope the good Dr. can guarantee pure water and help less fortunate people out. Hmm…interesting article. Dr. Amburgey has got a novel idea there.
