Abstract
Water treatment and purification system as disclosed herein relates to a PLC controlled system utilizing a hydroxyl radical generation unit and system to treat polluted water. The system uses a hydroxyl-based advanced oxidation based on natural processes that keeps our atmosphere clean and breathable. This technology creates its own high concentration of hydroxyls that are put through a venturi system into the water to be purified to eliminate unwanted organic compounds such as hydrogen sulfide, pathogens, chloride resistant parasites, and harmful bacteria. The system can also reduce inorganic contaminants including iron and manganese.

Patent decomposing them through "cracking", often acting as the first step to their removal. The system as described herein related to the use of OH radicals, that oxidize organic compounds.
Hydroxyl radicals play a key role in the oxidative destruction of organic pollutants using a series of methodologies collectively known as Advanced Oxidation Processes (A0Ps). The destruction of pollutants in AOPs is based on the non-selective reaction of hydroxyl radicals on organic compounds. These radicals are highly effective against a series of pollutants including pesticides, pharmaceutical compounds, dyes, etc. The hydroxyl radical can damage virtually all types of macromolecules: carbohydrates, nucleic acids (mutations), lipids (lipid peroxidation), and amino acids (e.g. conversion of phenylalanine to m-tyrosine and o-tyrosine). The hydroxyl .. radical has a very short in vivo half-life and a high reactivity. This makes it a very dangerous compound to any organism. Unlike superoxide, which can be detoxified by superoxide dismutase, hydroxyl radicals cannot be eliminated by an enzymatic reaction.
In the currently described system, the hydroxyl radicals are produced using ultraviolet irradiation. Typically, the UV irradiation used is short wavelength ultraviolet (ultraviolet C or UV-C) light. The hydroxyl radicals that are produced then kill or inactivate organic material and microorganisms such as bacteria, viruses, molds, and other pathogens. This is achieved by destroying nucleic acids and disrupting the DNA of the microorganism, leaving them unable to perform vital cellular functions. Subsequent filtration of the purified water removed the inactivated organic matter.
Devices and methods for carrying out the invention are presented in terms of embodiments depicted within the FIGS. However, the invention is not limited to the described embodiments, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and the configurations shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.

When the check valve 306, which is controlled by the programmable logic controller (PLC) 212, is open, the water in the water circulatory system 214 continues to travel in the direction as indicated by Arrow C.
