The patented, Low Temperature Distillation technology (LTDis) is a thermal process that uses specially designed direct evaporators and condensers for a very efficient heat transfer. The billions of droplets of water in the LTDis process have several functions. They provide a transport media (“carrier”) for the energy and heat in the system and also serve as a surface area for the heat exchange and evaporation/condensation processes which eliminates most scaling and fouling. The technology has the ability to operate at high concentrations (up to and into precipitation of the dissolved solids typically about 330,000 ppm) and achieve high conversion ratios. The main applications are wastewater streams from oil and gas produced water, RO brine streams, industrial wastewater, and solution mining.



The innovative, drying process is a low-pressure and low temperature system which allows for the use of different heat sources (e.g. waste heat) with heat recovery. Applications include drying of salt and other minerals for various industrial applications. LTDry is used in conjunction with the LTDis unit in order to achieve zero liquid discharge.

LTDis and LTDry: the flexible and economical way to ZLD


Combining LTDis and LTDry offers robust, efficient and economical solutions to achieve ZLD – including full separation of water and solids. The technology can operate under varying heat loads which makes the system ideally suited to use waste heat and solar, as well as traditional methods of energy sources.

Capable of integrating low grade energy sources, including waste heat and solar.  

LTDry uses a carrier material for the evaporative process to take place. This greatly reduces the problems associated with scaling and fouling consistent with other technologies

Together, the technologies offer an ideal route to ZLD. The objective is to achieve a near 100% removal of the water in all wastewater feeds.
