A scientist from the city, Dr Prashant Sharma has invented a ‘Bacterial e-ball’ that helps in cleaning drains and dirty pond water. These e-balls also improve the pH value and TDS (Total Dissolved Solid) value of the water. Sharma told ANI, "Bacterial e-ball consists of tiny microbes. It is prepared by mixing 14 types of fungus and bacteria with calcium carbonate (lime powder) in a ball that weighs around 40 grams. We have worked for around 14 years in inventing the ball. As soon as we put the bacterial e-ball in the dirty water of a pond or well, it cleans the upper layer of the water. It cleans the water by the nutritional use of carbon and nitrogen present in the ponds. It brings the pH value of the water to 7 and also improves the TDS value. Besides, the COD (chemical oxygen demand) and BOD (biochemical oxygen demand) levels of the water are also improving by its uses."
