Abstract:
1. A water treatment system including a media in the form of a multilayered semi porous composite sheet providing a strong positive electrical charge with a highly porous surface consisting of 60 to 90 percent void volume and pore size of about 2 micron capable of retaining negatively charged protozoa, bacteria, and virus as well as di-pole particulate matter as a result of the attraction of the positive charge, the media containing two sheets of polymer scrim with Nano glass fibers and bonded Nano alumina fibers encased between the sheets, the sheets having a nominal pore size of between one and two microns and from 0.5 to 2 mm in thickness exhibiting a very high porosity, given a solids content of 40 percent to as little as 10 percent of the membrane volume, yet exposing up to 400 bonding sites within each vertical pore and minimum pressure drop of 0.3 to 20 psig, with a flow rate of about 10 ml/sec to about 30 ml/sec; a housing being a portable adaptive housing containing and supporting the composite sheet, and a stream of water being a low pressure stream of water within the housing and through the media, the composite sheet being positioned within the adaptive housing in the path of the low pressure stream of water.
