Abstract
A media in the form of a multilayered semi porous composite membrane containing 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. A housing is a portable adaptive housing containing and supporting the composite membrane. A low pressure stream of water is within the housing and passes through the media. A composite membrane is positioned within the adaptive housing in the path of the low pressure stream of water. The composite membrane is adapted to treat the low pressure stream of water under from 0.3 to 10 psig pressure delivering 5 to 30 ml/sec.
