Processes and systems suitable for purifying or otherwise treating liquids to remove contaminants therein, including but not limited to contaminated water, to permit reclaiming, recycling, and reuse of the liquids. Such a process and system entails the use of a cascading distillation system that evaporates a liquid from the feedstock and then condenses and collects a more purified form of the liquid. The cascading distillation system can be operated to selectively process the feedstock through any of a series of vessels at which different amounts and/or contaminants may be removed from the feedstock.

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.

The disclosure relates to systems for treating water and method for use.

The present invention discloses a novel hydrophilic and compressible aerogel as draw agent for purification water in forward osmosis (FO), which belongs to environmental pollution control engineering technical field. The improved performances are obtained by optimizing regeneration process of drawing and producing water by using this aerogel as a draw agent in FO technology. Herein, the aerogel complete avoid the draw solution's reverse diffusion and maintain a higher water flux that compensates for its structure characteristics. Moreover, the regeneration of the draw agent and production water should be accomplished through human compression without a complicated physical and chemical method. Simultaneously, this draw agent presents other advantages of wide raw material sources, low cost, wild preparation process, low poison and good film compatibility. It is an innovation as FO technology in portable water purifying device, especially in areas of military and emergency.

A fluid transport assembly includes a substantially cylindrical shell having a first closed end and a second closed end and a tube extending from the first closed end to the second closed end. The tube is substantially aligned with an axis of the shell and provides a passage through the shell. The fluid transport assembly also includes a series of concentric cylindrical filters positioned in the cylindrical shell and extending from the first closed end to the second closed end. The series of concentric cylindrical filters defines an input compartment between the filters and the tube and an output compartment between the filters and the cylindrical shell. The series of concentric filters is structured to remove contaminants from a fluid as the fluid flows through the series of concentric filters from the input compartment to the output compartment.
