Abstract
A desalination system and method for controlling the desalination system include thin-filmed photocatalyst coated glass tubes which perform a photocatalytic cleaning reaction to remove contaminants. A first flow control valve directs the contaminant-free feed water either to a feed water heater for pre-heating or to a geothermal energy-based heat exchanger. A second flow control valve directs a first portion of the pre-heated contaminant-free feed water to a thermal energy storage tank and a second portion to a flash chamber for steam generation. A condenser connected to the flash chamber includes a nano-fluid cooling coil that condenses steam into potable water.
Claims13
A method of controlling a desalination system, comprising:
- receiving, by a microprocessor including electrical circuitry, a memory storing program instructions and at least one processor, light intensity measurements from the light sensor operatively connected to the desalination system;
- executing, by the processor, the program instructions to control a feed pump, a first flow control valve, a second flow control valve, a nanofluid pump, a vacuum pump, a switch of an electric powered ultraviolet (UV) light source and a heating element located within interior walls of a flash chamber based on the light intensity measurements from the light sensor;
- and
- producing potable water from feed water,
- wherein the desalination system comprises:
- a feed tank fluidly connected to a feed water supply;
- the feed pump fluidly connected to the feed tank;
- a plurality of thin-filmed photocatalyst coated glass tubes fluidly connected to the feed pump, wherein the feed pump is configured to pump feed water from the feed tank through the plurality of thin-filmed photocatalyst coated glass tubes, wherein the plurality of thin-filmed photocatalyst coated glass tubes are configured to catalyze a photocatalytic cleaning reaction which removes contaminants from the feed water;
- the first flow control valve connected to the plurality of photocatalyst coated glass tubes, wherein the first flow control valve has a first mode in which the contaminant-free feed water is fluidly directed towards a feed water heater which is configured to pre-heat the contaminant-free clean water and a second mode in which the contaminant-free feed water is fluidly directed into a geothermal energy based heat exchanger;
- the second flow control valve configured to fluidly direct a first portion of the pre-heated contaminant-free feed water into a thermal energy storage tank and a second portion of the pre-heated contaminant-free feed water into a flash chamber, wherein the flash chamber is configured to generate steam by flash heating the pre-heated contaminant-free feed water;
- a condenser connected to the flash chamber, wherein the condenser includes a nano-fluid cooling coil, wherein the condenser is configured to condense the steam into potable water;
- and
- a distillate collection tank located beneath the condenser, wherein the distillate collection tank is configured to collect potable water.
