Neutralization system
A neutralization system is used in the broadest sense to convert harmful intermediate products by processing or converting them into harmless end products, which can optionally be fed to a simplified further processing. With liquids, such a system uses the chemical process of neutralization in order to reach a certain pH level.
functionality
With the help of liquid neutralizing agents such as caustic soda (NaOH), hydrochloric acid (HCl) or sulfuric acid (H 2 SO 4 ), the pH value is brought to the required level. The liquid to be treated flows through the reactor in a free gradient from the inlet to the outlet. A stirrer creates an even mix and the pH value is constantly measured and monitored. Depending on the pH value of the material to be neutralized, acid or alkali is dosed and mixed in in appropriate quantities. Once the desired process values have been set, they are checked again during the process and recorded using a digital recorder.
Areas of application
In the waste water treatment neutralization systems are used to waste water to a for sewage acceptable pH level to adapt, such as in the combustion resulting condensate by condensing boilers . Other areas of application can be found in the food industry, in large kitchens, with beverage producers, in laboratories, paper mills, dairies, slaughterhouses, surface technology companies such as electroplating, pickling or dyeing factories. With the help of neutralization systems, they can all neutralize all acidic and alkaline wastewater directly at the emission source.
Other areas of application are production processes in which the pH value has to be corrected within a process chain.
