Their full attention is focused on the soft drinks, they are not enough experience for building a comprehensive solution to follow all requirements of environmental protection. Even though the basic design of wastewater treatment section is principally similar, but the process systems in plants are different while the precondition for efficient measurement is the knowledge about the process characteristics of the individual plant sections. 

     For this reason, PepsiCo relies on NK Engineering and its years of know-how in industrial measuring instruments to install an automatic wastewater quality monitoring station as The Ministry of Natural Resources and Environment requested.
