Water Recycling Made Faster and Cheaper
By Nick June 13, 2008
With drought and other water restrictions being experienced globally these days, a timely invention has recently taken shape – Bay Area California scientist Meng Lean’s water filtration method, that filters water five times faster and cheaper than existing systems.
The idea came into being during a time Lean was commissioned by the U.S. Army for water-purifying services to soldiers deployed in the field. He worked in a cramped Palo Alto laboratory which eventually served as the launching pad of his own brand of water purification technology.
The system, which Lean himself admits is still far from perfect, involves a spiral filtration system where water is funneled through spinning lightweight disks. The extraordinary speed involved in the spinning process makes possible the separation of dirt particles, leaving water that is cleaner. The resulting water may not be potable, but it can be used for agricultural activities.
Aside from being a fast system, Lean’s invention is also cheap and does not require acres of space to house it.
At the moment, Lean leads a team of experts in continuously refining the system. He further admits that a lot of work still has to be done, especially involving the elimination of microscopic viruses that are still able to escape the water treatment process that they are developing. By the end of the current month, the group plans to embark on a larger-scale operation in which their target is to recycle 100 liters of water per minute.
