What is Vapor Compression?
In terms of distillation, Vapor Compression, or VC, refers to Mechanical Vapor Compression (MVC) technology, which is utilized to impart energy (in the form of heat) to evaporated water (i.e. vapor) through centrifugal compression. Vapor Compression is much more efficient in distilling water compared to older technology, which requires massive amounts of thermal energy input (i.e. plant steam, electrical heaters) applied over a multi-pass evaporation/condensation process.

What Is Reverse Osmosis?
Reverse Osmosis (i.e. RO) is a process whereby water is purified by passing a stream of incoming feedwater through a semipermeable membrane(s), counteracting natural osmosis that would occur without the force applied by the high pressure pump. Feedwater is passed through a particulate filter and then pumped through the RO vessels where the separation occurs into two streams – permeate, or the purified water, and the reject / concentrate discharge.
