Neptune provides produced water recycling and frac water disinfection services. The core of our technology is our Mobile Trea ... tment Units (MTUs) that utilize De Nora's ChlorTec system that generates an oxidant (sodium hypochlorite- otherwise known as bleach) using only salt, water, and electricity.
