Abstract
The present disclosure relates to a system and method for treating wastewater, the method comprising the steps of: providing a vessel for receiving wastewater and a gas, wherein the gas comprises one or more constituent gas components; directing the wastewater and a first gas component of the gas to the vessel; reducing the temperature of the contents of the vessel from a first temperature to a second temperature to facilitate the formation of clathrate hydrates comprising the wastewater and the first gas component; increasing the temperature of the contents of the vessel with respect to the second temperature to facilitate melting of the clathrate hydrates; and removing clean water and/or the first gas component from the vessel.
Claims24
A method of treating wastewater, the method comprising the steps of:
- providing a nanobubbles generator comprising a volume for receiving a liquid, providing a liquid in the volume, and distributing a gas within the liquid in the volume, the gas comprising one or more constituent gas components;
- generating a static electric field using an electrode in the proximity of the volume of the nanobubbles generator for facilitating the generation of nanobubbles of a first gas component;
- wherein the electrode and the liquid are not in direct electrical contact to prevent electrolysis occurring within the volume of the nanobubble generator;
- providing a vessel for receiving wastewater and the nanobubbles of the first gas component;
- directing the wastewater and the nanobubbles of the first gas component to the vessel,
- reducing the temperature of the contents of the vessel from a first temperature to a second temperature to facilitate the formation of clathrate hydrates comprising the wastewater and the first gas component;
- increasing the temperature of the contents of the vessel with respect to the second temperature to facilitate melting of the clathrate hydrates;
- and
- removing clean water and/or the first gas component from the vessel.
