Activated carbon is also employed in municipal wastewater treatment plants as a fourth purification stage to remove trace substances like drug residues and microplastics, thereby enhancing water pollution control. At the adsorption station, clear tap water is dyed and introduced into the wastewater tank for illustrative purposes. A second tank receives the purified water. For operational convenience, the colored water can be continuously pumped through the activated carbon filter within the circuit of the first tank, under observation, until the desired level of decolorization is achieved. Subsequently, a solenoid valve can be activated to redirect the flow of water to the clear water tank. For automated operation, the piping system is equipped with a flow meter, a pressure sensor, and a smart arti:sens photometer. Signal processing of the photometer is employed to control the solenoid valve automatically. The station comprises two filter modules and additional piping materials, allowing flexibility for various operational modes. It can function either with the filter modules in series, which increases the filtration capacity but necessitates plant shutdown for filter replacement, or in parallel, where one of the two filters can be removed during operation, for instance, to replace the activated carbon. The remaining filter can continue to operate at a reduced flow rate.
