Apparatus and method for waste-water reduction in laboratory water purification system

Abstract

A water purification system, comprising: a water feed path configured to receive an input water; a reverse osmosis module configured to (1) receive input from the water feed path and (2) output a permeate and a concentrate; and a recycle loop, the recycle loop being in fluid communication with the reverse osmosis module and the recycle loop being configured to receive the concentrate of the reverse osmosis module, the recycle loop being in fluid communication with an output and being configured to communicate a first portion of the concentrate to the output, and the recycle loop being convertible between (1) a recirculation state in which a second portion of the concentrate is communicated to the water feed path and (2) a standard state in which the second portion of the concentrate is communicated to the output.
