Abstract: A method for water purification utilizing a cylindrical vessel containing a hydrocyclone nest. The heated contaminated water is fed into the nest, which includes a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the hydrocyclones in each set arranged in parallel, and each set arranged in series. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of each 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 into the subsequent set of hydrocyclones until the final set of hydrocyclones, and then out through a second outlet of the cylindrical vessel. The steam is condensed into purified water.

Abstract: An apparatus for use in water purification including a cylindrical vessel comprising, within the cylindrical vessel, a first set of hydrocyclones, at least one intermediate set of hydrocyclones, and a final set of hydrocyclones, the sets of hydrocyclones arranged in series. In one embodiment, the hydrocyclones within each set of hydrocyclones are arranged in a parallel configuration, wherein each set of hydrocyclones is defined by a divider which causes the hydrocyclones in each set to operate in parallel. In one embodiment each hydrocyclone has a tangential inlet disposed within an inlet chamber of the cylindrical vessel and in fluid communication with an inlet connected to the inlet chamber, an overflow disposed within an overflow chamber of the cylindrical vessel, and an underflow disposed within an underflow chamber of the cylindrical vessel. In one embodiment, the cylindrical vessel comprises a first set of hydrocyclones and a second, final set of hydrocyclones.

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.
