Introduction

Anthony S Walsh is an accomplished inventor based in Vancouver, Canada. He has made significant contributions to the field of environmental engineering, particularly in the treatment of acidic waters. His innovative approach addresses the challenges posed by metal-containing acidic mine wastewater.

Latest Patents

Walsh holds a patent for a method titled "Method for treating acidic waters using recycled acidic and basic sludges." This method effectively removes metals from acidic mine wastewater by utilizing a basic sludge produced during the treatment process. The wastewater is mixed with a lime slurry and the basic sludge, allowing it to separate into an aqueous effluent and an acidic sludge. The effluent is then treated further with a composition containing an iron compound, leading to the production of a cleaner effluent. Additionally, lignin derivatives, such as calcium lignosulfonate, may be included in the treatment mixture to enhance its effectiveness.
