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.
Claims17
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.
A water treatment system including a media and a housing and a stream of water, the media being 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 ˜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 membrane, the housing being a portable adaptive housing containing and supporting the composite sheet, and the 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, the composite sheet being adapted to treat the low pressure stream of water under from 0.3 to 20 psig pressure delivering 5 to 30 ml/sec for the reduction of biological contaminants consistent with the recommendations of the EPA, 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., the media also containing within the body of the membrane structure powered activated carbon effective for the removal of chemical contaminants such as chlorine, the carbon representing about 30 percent by weight of the membrane, the media being in a cylindrical configuration with an undulating accordion-like cross sectional configuration, the media having a top with egress opening and base closure and the housing being a bottle with a top, and with means to attach the media cooperatively with the bottle for the purpose of treating the water as the water is being removed from the bottle.
