Waterworks Essbio, Chile


Courtesy of

For the waterworks in Essbio, Chile, Grundfos Alldos developed a decentralized, computer aided disinfection system networked with the entire system of the La Mochita waterworks. The 600.000 inhabitants of Concepción are supplied with treated water from a river. The water is decontaminated with chlorine gas for economical reasons and for better handling. Exact dosing minimizes the consumption. The full vacuum system offers a high degree of safety for all three decontamination levels. Thanks to the Modem connection, Grundfos Alldos is always in a position to check the whole system, to call and check the settings in Germany. Costly maintenance on site or fault detection are not necessary. Disturbances in the software can be quickly eliminated.
