Electroplating has many uses ranging from the purely cosmetic to the application of protective coatings. The process, which uses electric current to drive ions towards receptive metal surfaces, is sensitive to multiple key parameters and careful control is crucial to achieving desired plating effects. Several components, including the concentration of ions in the plating bath, [...]
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 to [...]
Environmental Impact of Stormwater Monitoring Stormwater runoff from industrial facilities can pose a threat to the environment, as precipitation may pick up pollutants and wash them into local water systems. The results can be devastating: habitat degradation, siltation of rivers and depletion of fish populations can all occur. Because of these risks, stormwater runoff [...]
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.
Cyanide waste treatment is critical, because cyanide wastes are toxic to living organisms. Specifically, cyanide may reduce or eliminate oxygen utilization in organisms, including human beings, making cyanide poisoning potentially fatal. Aquatic life, including microorganisms involved in natural water purification streams, is particularly susceptible to cyanide poisoning.
