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.

An amphoteric two-dimensional nanosheet and a preparation method thereof are provided. The amphoteric two-dimensional nanosheet is prepared by the following steps: uniformly dispersing few-layered graphene oxide into toluene and then adding alkylamine coupling agent to a mixture of the few-layered graphite oxide and the toluene for reaction; amine terminated graphite oxide dispersion that has been prepared is fully dispersed in toluene-dimethylformamide mixed solvent, and then, alkyl glycidyl ether is added into the above solution for reaction, so as to obtain the amphoteric two-dimensional nanosheet. The amphoteric two-dimensional nanosheet of the present disclosure can be prepared by modifying two-dimensional graphite oxide, to spontaneously form water-in-oil Pickering emulsion at an oil-water interface, compared with emulsion of conventional surfactants, the present disclosure can effectively stabilize the waterflooding front, improve the sweep volume of waterflooding, have a simple synthesis process for convenient large-scale production, and be widely used in waterflooding development reservoirs.

The present invention provides a safe, disposable and biodegradable chlorine dioxide micro generator that uses water soluble paper and hydrogel or compressed cellulose encased in filter paper pouch. The chemicals are kept in a stabilize form until activated by the addition of water. Multiple levels of protection against early exposure to water such as a foil pouch and an impermeable outer container allow for the safe transportation and storage in small, ready for deployment amounts of the chemicals. Water permeated the chemical pack housing and dissolves the paper walls of the chemical pouch housing and then the water facilitates the reaction between the acid and the sodium chlorite to form chlorine dioxide gas as will be described further hereunder. Absorbent and permeable materials packaged around the chemicals provide for the safe containment of the chlorine dioxide solution, and the expeditious aeration and release of the chlorine dioxide gas, once the chemical reaction has been completed.
