Title: Innovations in Water Treatment: The Contributions of Daniel J. Cho

Introduction

Daniel J. Cho, an innovative inventor based in Wayne, PA, has made significant contributions to the field of water treatment through his patented technologies. With a total of three patents, he has focused on addressing the challenges posed by adulterated water, particularly in the context of hydraulic fracturing.

Latest Patents

Among his latest inventions, Cho has developed a "System and method for disinfection and fouling prevention in the treatment of water." This advanced treatment system utilizes a combination of plasma spark discharge and an RF oscillating electric field to effectively treat produced water, particularly that generated during hydraulic fracturing. By employing these technologies within a chamber, the system not only eliminates microorganisms but also greatly reduces or eliminates fouling caused by bicarbonates. Additionally, grids are incorporated to enhance the heating effects produced by the RF oscillating electric field.

Another noteworthy invention from Cho is the method for "Pre-treating water with non-thermal plasma." This process aims to treat adulterated water, especially that which is created during the fracking of shale rock in natural gas drilling. The innovative method specifically targets water containing high levels of bicarbonate and calcium ions, modifying it through exposure to non-thermal arc discharge plasma to achieve a significantly lower level of bicarbonate.
