NPC - Neutralisation Process Controller

Less water consumption and sewage and simultaneously higher availability and neutralization efficiency

The controller features all functions of a neutralization washer. In connection with a Ph measurement device it ensures that the neutralization performance of the washer is not hindered by a high salt concentration and still uses the least amount of water and chemicals.

In addition an automatic neutralization of the sewage is integrated. Several safety features take care of the redundancy of the acid injection control.

The environmentally compatible principle of neutralization of the fermentation air with help of sulfuric acid leads to the final product ammonium sulfate which is a fertilizer for agriculture:
H2SO4 + 2 NH3 = (NH4) 2SO4
