1. A liquid treatment system using high intensity broad-spectrum pulsed light to reduce physical, chemical, biological, or microbiological contaminants, the system comprising:
a reactor having a shell, a liquid inlet, a liquid outlet, a plurality of tubes, and a plurality of light sources disposed between the liquid inlet and the liquid outlet,
wherein each of the plurality of light sources is respectively contained within the plurality of tubes;
an ionized wire wrapped outside each of the plurality of light sources of the reactor inside the plurality of tubes;
at least one power supply to power the plurality of light sources of the reactor;
at least one digital multiplexer connected to the at least one power supply; and
a controller to:
control the at least one digital multiplexer to power the plurality of light sources to strobe pulsed light with a predetermined fluence to treat contaminants,
wherein the reactor further includes:
an enclosure, the enclosure having a first end and a second end;
a first outer cap housing the first end of the enclosure; and
a second outer cap housing the second end of the enclosure,
wherein the first end of the enclosure includes a first inner cap and the second end of the enclosure includes a second inner cap,
wherein the first inner cap is fluidly connected to the liquid inlet, and the second inner cap is fluidly connected to the liquid outlet,
wherein a portion of the first inner cap that is configured to receive the liquid and a portion of the second inner cap connected to the liquid outlet are curved and configured to create turbulence of liquid flow in a circular motion in the reactor, and
wherein the plurality of light sources is provided concentrically around a center axis of the reactor in the shell such that an internal space is formed between the shell and the plurality of tubes such that liquid passes through the internal space in the circular motion between the shell and the plurality of tubes and between the plurality of tubes from the liquid inlet to the liquid outlet.
 
12. A method of reducing physical, chemical, biological, and microbiological contaminants, the method comprising:
powering, by at least one power supply, a plurality of light sources of a reactor via at least one digital multiplexer connected to the at least one power supply,
wherein the reactor includes a shell, a liquid inlet, a liquid outlet, a plurality of tubes, an enclosure, the enclosure having a first end and a second end, a first outer cap housing the first end of the enclosure, and a second outer cap housing the second end of the enclosure, wherein the first end of the enclosure includes a first inner cap and the second end of the enclosure includes a second inner cap, wherein the first inner cap is fluidly connected to the liquid inlet, and the second inner cap is fluidly connected to the liquid outlet, and the plurality of light sources disposed between the liquid inlet and the liquid outlet, and an ionized wire is wrapped outside each of the plurality of light sources of the reactor,
wherein each of the plurality of light sources having the wrapped ionized wire is respectively contained within the plurality of tubes;
creating turbulence of liquid flow in a circular motion in the reactor, wherein a portion of the first inner cap that is configured to receive the liquid flow and a portion of the second inner cap connected to the liquid outlet are curved, and
wherein the plurality of light sources is provided concentrically around a center axis of the reactor in the shell such that an internal space is formed between the shell and the plurality of tubes such that the liquid flow passes through the internal space in the circular motion between the shell and the plurality of tubes and between the plurality of tubes from the liquid inlet to the liquid outlet;
controlling, by a controller, the plurality of light sources to strobe pulsed light with a predetermined fluence to reduce physical, chemical, biological, or microbiological contaminants at a molecular level.
