1. The portable filtration system comprising:
a membrane portion including:
a filter;
a boost pump;
a membrane apparatus having a permeate chamber and a concentrate chamber segregated by a membrane;
a recycle passage;
a concentrate passage; and
an energy recovery apparatus, wherein
the membrane apparatus is in fluid communication with a feed pump via an output passage, the filter, and the boost pump, and wherein
the concentrate passage is in fluid communication with the concentrate chamber and the energy recovery apparatus, and the concentrate passage is configured to carry a high-pressure concentrate fluid from the concentrate chamber to the energy recovery apparatus, and wherein
the recycle passage is in fluid communication with the energy recovery apparatus and a mixing chamber of a mixing portion via a contaminant regulator, and the recycle passage is configured to carry a low-pressure concentrate fluid from the energy recovery apparatus to the mixing chamber of the mixing portion via the contaminant regulator.
