Possibilities of Pharmaceutical Wastewater Generating Hydrogen Gas Potential Hydrogen Production from Pharmaceutical Wastewater

Abstract

Over the past fifty years, there has been a sharp surge in the search for clean, high-energy fuels. Fossil fuels, which are a primary source of energy, release harmful air pollutants into the environment which are posing a substantial air pollution issue. Compared to fossil fuels, hydrogen gas is a clean and having a high heating value. Hydrogen is thought to be the main energy carrier of the future and can be utilised in fuel cells to produce electricity. The present paper gives an insight for hydrogen gas (H2) production from the pharmaceutical wastewater. Out of the many technologies available for hydrogen production form the water, sludges & sewage &/or wastewater, electro-hydrolysis is one of the most researched technologies from production of hydrogen from waste & wastewaters. The lab scale electro-hydrolysis treatment was given having iron electrodes to real treated pharmaceutical wastewater. The wastewater samples were collected from each stage of the treatment plant in order to evaluate the treatment efficiency. The hydrogen gas production after electrolysis treatment was confirmed with the flame testing method.
