Hydrodynamic forces to clean water

The Palo Alto Researh Centrer (PARC) has developed a new filterless technology for making clean water in wastewater plants. 

The Palo Alto Research Center, set up in 1970 by Xerox, is a research and development company responsible for important developments such as laser printing, Ethernet, the modern personal computer and graphical user interface (GUI). After three decades as a division of Xerox, PARC was transformed in 2002 into an independent, wholly owned subsidiary R&D company in Sillicon Valley. It has a few areas of focusincluding clean technology and solar.  Now they’ve made a breakthrough in clean water technology. They have been using Xerox’s know-how in working with small pieces of plastic, namely the bits of toner inside a printer, and applying that to figuring out how to take dirt out of water. 

The technology developed by PARC is called Hydrodynamic Separation (HDS). The separation solution is based on a simple concept: the system pumps water through a spiral tube to seperate unwanted particles. Controlled by centrifugal and hydrodynamic forces these particles are moved towards one wall of the tube where they can be split off to a waste stream. This enables a continuous flow seperation of clean effluent from the waste stream. The system is said to be capable of high rates of flow, use low energy (or use a gravity-fed source), and because of its compact size and modular design, can be scaled up or down to fit the site.

According to PARC This separation system could transform the ways in which water is treated for various uses including: desalination pre-treatment, produced water treatment, algae de-watering, cooling tower water treatment.Parc plans to work with partners to scale up and commercialize this water treatment technology.
