<p>A portable filtration assembly includes a housing containing a water inlet port and a water outlet port and a sub-micron filter disposed in the housing having hydrophilic sub-micron rated membrane filter elements. The sub-micron filter is configured to effect a six log reduction of bacteria (99.9999%) and a four log reduction of protozoa (99.99%) at a flow rate between 10 - 30 mL/sec requiring a pressure of 1.5 - 10 psi. The assembly also includes structure for venting air through the hydrophilic sub-micron rated membrane filter elements. The assembly may additionally include a monolithic radial flow carbon composite filter also disposed in the housing. The monolithic radial flow carbon composite filter is configured for removing at least 80% of chlorine and at least 90% of lead over a minimum of forty gallons at a flow rate of 10 mL/sec at a pressure drop of 10 psi or less.</p> |
