A technology that provides various modular biomimetic microfluidic modules emulating varieties of microvasculature in body. These microfluidic-base capillaries and lymphatic Technology modules are constructed as multilayered-microfluidic microchannels of various shapes, and aspect ratios using diverse biocompatible microfluidic polymers. Then, various semipermeable membranes are sandwiched in between these multilayered microfluidic microchannels. These membranes have different chemical, physical characteristics and MWCO values. Consequently, this design will produce much smaller dimension channels similar to human vasculature to achieve biomimetic properties like of human organs and tissues. By interchanging microfluidic-layers or the membranes various diverse modules are designed that act as building blocks for constructing various medical devices, various forms of dialysis devices including albumin and lipid dialysis, water purification, bioreactors, bio-artificial organ support systems. Connecting various modules in diverse combinations, permutations, in parallel and/or in series to ultimately design many unrelated medical devices such as dialysis, bioreactors and organ support devices.

A separation membrane module comprises a hollow module container, and an element unit which is housed in the module container. The element unit comprises a plurality of connected separation membrane elements each of which includes: a separation membrane for separating components of a substance flowing to the inside of the module container; and membrane bundle securing materials for securing both ends of the separation membrane. In the element unit, a flow channel for discharging the components separated by the separation membranes to the outside of the element unit is formed. Passage members though which the components separated by the separation membranes can pass toward the flow channel for discharging are disposed at connections between the plurality of separation membrane elements such that both end surfaces of each of the passage membranes are respectively in contact with the membrane bundle securing materials of the separation membrane elements adjacent thereto.

A portable water filtration system that is configured to provide potable water from a contaminated water source. The portable water filtration system includes a pre-treatment module and a polishing module that are fluidly coupled and contained within a stackable housing configuration. The pre-treatment module has disposed therein a pump, two solenoid valves, a first filter and a pair of ultra-filters wherein the aforementioned elements are all fluidly coupled utilizing plastic tubing. Water is cycled through the elements of the pre-treatment module and is then directed to the polishing module. Disposed within the polishing module are four filters that have filtration material therein operable to filter material within a range of 0.0002 to 0.0009 microns. The portable water filtration system is operable in a filtration mode and a flush mode.
