Abstract
Devices, systems, and methods for the purification of water with a photoreactor. A continuous flow water purification photoreactor having a water inlet, a plurality of illumination sources disposed about a central axis facing and having n-fold rotational symmetry about the central axis, a reaction tube, and a water outlet. The reaction tube including a set of bundled rods having m×n-fold symmetry wherein the bundled rods include a photocatalyst support material at least partially coated with a photocatalyst film.
Claims22
A continuous flow water purification photoreactor, comprising:
- a water inlet;
- a plurality of illumination sources disposed about a central axis facing and having n-fold rotational symmetry about the central axis, where n is a whole number;
- a reaction tube comprising:
- a set of bundled rods having m×n-fold symmetry, where m is a rational number and wherein the bundled rods comprise a photocatalyst support material at least partially coated with a photocatalyst film;
- and
- a water outlet, wherein the water inlet is fluidly coupled to a proximal end of the reaction tube and the water outlet is fluidly coupled to a distal end of the reaction tube.
A water purification system, comprising a continuous flow water purification photoreactor coupled to a water source, the continuous flow water purification photoreactor, comprising:
- a water inlet;
- a plurality of illumination sources disposed about a central axis facing and having n-fold rotational symmetry about the central axis, where n is a whole number;
- a reaction tube comprising:
- a set of bundled rods having m×n-fold symmetry, where m is a rational number and wherein the bundled rods comprise a photocatalyst support material at least partially coated with a photocatalyst film;
- and
- a water outlet, wherein the water inlet is fluidly coupled to a proximal end of the reaction tube and the water outlet is fluidly coupled to a distal end of the reaction tube.
A method of purifying water, comprising passing the water to be purified through a continuous flow water purification photoreactor, the continuous flow water purification photoreactor, comprising:
- a water inlet;
- a plurality of illumination sources disposed about a central axis facing and having n-fold rotational symmetry about the central axis, where n is a whole number;
- a reaction tube comprising:
- a set of bundled rods having m×n-fold symmetry, where m is a rational number and wherein the bundled rods comprise a photocatalyst support material at least partially coated with a photocatalyst film;
