Monitoring dissolved oxygen is an important part of the activated sludge process. It assists in ensuring that there is sufficient dissolved oxygen in the process for the biological activity to take place, and helps to optimize energy usage through controlled air addition. In some cases, aeration accounts for between 2% and 3% of their annual energy costs. Maintaining a proper level of dissolved oxygen can only be accomplished by using an on-line instrum…

BREAKPOINT CHLORINATION AS AN ALTERNATE MEANS OF AMMONIA/NITROGEN REMOVAL AT A WATER RECLAMATION PLANT

Numerous wastewater treatment processes are currently available for nitrogen removal or ammonia conversion to nitrate.  
  • Those that are economically feasible rely mostly on microbiological processes, which are only effective when the microorganisms remain in a healthy state.
  • If a biological process upset was to occur, due to a toxic shock load or c
