Abstract
A water purification system includes a high temperature water tank, a flameless heat source, a cylindrical vessel (hydrocyclone nest), a first pump, a steam production meter, and a steam condenser and heat exchanger. The contaminated water is heated within the high temperature water tank using the flameless heat source. The heated contaminated water heats the cylindrical vessel and one or more sets of hydrocyclones. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and a second outlet of the cylindrical vessel. The steam is condensed into purified water using the steam condenser and heat exchanger.
