Title: The Innovative Contributions of Stephen Howard Brown
Introduction
Stephen Howard Brown is a notable inventor based in Spencer, MA (US). He has made significant contributions to the field of waste treatment through his innovative patents. With a total of 2 patents, Brown has developed processes that aim to improve environmental sustainability.
Latest Patents
One of his latest patents is the BioCAST process. This waste treatment process includes an ammonification system that converts soluble organic nitrogen into ammonia nitrogen. It is followed by a physico-chemical process that removes a substantial amount of ammonia, recovering it as either ammonium sulfate fertilizer or ammonium hydroxide, also known as 'aqua ammonia'. The process effectively reduces ammonia and carbonaceous organic matter to less than 10 mg/l while recovering ammonia in useful forms.
Another significant patent involves an ammonium removal method. This method includes removing a multivalent cation from a stream containing ammonium to create a treated stream. The process then converts ammonium into ammonia by increasing the pH of the stream and separates the ammonia from the treated stream, resulting in a separated stream and gaseous ammonia. This innovative approach can achieve a total of less than or equal to about 50 ppm by weight of multivalent cations in the treated stream.
