Title: Innovations by Shihwu Sung in Wastewater Treatment

Introduction

Shihwu Sung is an accomplished inventor based in Ames, Iowa, known for his contributions to wastewater treatment technologies. With a total of two patents to his name, he has developed innovative methods that address environmental challenges associated with sulfide removal and wastewater management.

Latest Patents

One of his latest patents is titled "Micro-aeration of sulfide removal from biogas." This novel method involves treating sulfide-laden biogas produced in a bioreactor within a sulfide oxidizing unit (SOU). The oxidation process in the SOU is monitored by an oxidation reduction potential (ORP) probe, which minimizes the input of air or oxygen to produce elemental sulfur while avoiding significant sulfate production.

Another significant patent is the "Method of treating wastewater using sequencing batch aerated lagoon." This process is conducted in a minimum of two earthen lagoons, providing treatment for municipal or industrial wastewater. The lagoons operate on a fill-draw basis in a sequential manner, allowing for continuous raw wastewater entry into one lagoon while the other lagoon discharges. This innovative approach ensures that the lagoon at full liquid level remains uncontaminated by raw wastewater, facilitating biological reactions under both aerobic and anoxic conditions.
