Chlorine for Wastewater Treatment The use of chlorine for water treatment has a long history since its first use in Jersey City in 1908. Despite the use of chlorine globally to produce safe drinking water, chlorination is not a simple process, especially considering that chlorine itself is toxic. More recently, we take great care [...]
Water Treatment Methods There exist several mechanisms for water disinfection, including chlorination and chloramination, ozonation, and UV irradiation. Ordinarily, only one disinfection technique is used in a treatment train. However, there are potential benefits to combining water treatment methods in sequence, including energy and cost savings and a safer product water. Potential Benefits of Combination [...]
Aeration wastewater treatment tanks are subject to careful monitoring to ensure that nutrient removal is achieved safely and efficiently. Dissolved oxygen is a critical parameter in the aeration process, because oxygen levels in the tank impact the health of the biomass (microorganisms) breaking down the nutrients. To maintain the proper oxygen levels for biomass productivity, wastewater treatment operators utilize aeration pumps, which add oxygen to the tanks.
