1. 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.
