Title: Daniel K Cha: Innovator in Hazardous Waste Treatment

Introduction

Daniel K Cha is an accomplished inventor based in Newark, DE (US). He has made significant contributions to the field of hazardous waste treatment, particularly in the production of energetics such as explosives. With a total of 2 patents to his name, Cha's work focuses on innovative systems designed to effectively manage and neutralize hazardous waste.

Latest Patents

Cha's latest patents include a "System for destroying hazardous waste resultant from the production of energetics" and a "Process for treating waste from the production of energetics." The first patent describes a waste stream treatment method that utilizes a pre-filter with media, preferably sand, and a reducing metal, such as elemental iron (Fe). This system connects to a zero-valent metal column reactor, where the waste stream undergoes a reducing process. The resultant product is then processed through a continuously stirred tank reactor (CSTR) for Fenton oxidation, followed by sedimentation and pH-neutralization. The second patent outlines a similar approach, emphasizing the integration of the pre-filter and reactor as a single unit to optimize waste treatment.
