Collection Tank and pH Adjustment

The waste flow and composition will vary for a number of reasons. Wide variation in the waste stream characteristics may cause process upsets that could take the system out of control and cause equipment failure. The primary method for reducing this variability is to install a tank to collect the waste from the clean room. The tank serves several purposes  

Granulated activated carbon (GAC) is commonly used in the water purification industry to remove oxidizers—such as chlorine—and some organics from municipal water treatment systems. GAC has also found a 

A third method for oxidizer reduction, namely, ultraviolet radiation, is based on recent developments made in the water purification industry to remove residual chlorine from city water used by the food, beverage, and pharmaceutical industries. In those applications, ultraviolet light at wavelengths between 254 and 310 nm is used to reduce the chlorine and chloramines
