A wet electrostatic precipitator (WESP) removes suspended particles and liquid droplets by charging them electrically, driving them toward collecting surfaces, and washing the deposits into a drainage system. The electric field performs the principal collection task; the liquid removes accumulated material from the surfaces. Understanding how a wet electrostatic precipitator works therefore requires following both […]

A continuous emission monitoring system (CEMS) measures selected pollutants and associated stack parameters, then records and processes those measurements into emissions information. Measurements may come from gas extracted from the stack or instruments operating directly in the gas stream. Reliable results depend on the complete chain: representative measurement, appropriate sample handling, suitable instruments, and data […]

Dry and wet electrostatic precipitators use electrical forces to collect particles from a gas stream. Their main difference is how they remove material from the collecting surfaces: a dry ESP typically dislodges deposits by mechanical rapping, while a wet ESP uses liquid washing. That distinction affects dust recovery, maintenance, water demand and waste handling. Dry […]

An online COD analyzer for wastewater should be selected according to how it produces its result and what the plant needs that result to support. A digestion analyzer determines chemical oxygen demand through a chemical oxidation procedure. A direct UV absorbance monitor measures an optical signal and uses a relationship with reference COD to estimate […]

Industrial air pollution control equipment is the group of technologies used to capture, remove or transform pollutants in industrial exhaust streams. The appropriate equipment depends first on what is in the gas: solid particles, mist droplets, soluble or reactive gases, volatile organic compounds (VOCs), or a combination. A fabric dust collector, wet scrubber, electrostatic precipitator […]

A baghouse dust collector is an industrial particulate-control device that uses fabric filter bags to separate suspended dust from an exhaust gas stream. Dust-laden air enters the collector, particles accumulate on the filter medium and the developing dust cake, and cleaned gas passes toward the outlet. A cleaning mechanism periodically dislodges deposited dust so it […]
