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.
