Question

An activated sludge process is being used to treat wastewater from a small town of 50,000 people, which includes intermittent industrial discharges that may have a toxic impact on the performance of the wastewater treatment plant(WWTP) a) What type of online equipment would you recommended be installed for early warnings of wastewater treatment failutre? b) Which parameters would you recommend be measured and where would these be positioned in the WWTP?

Answer 1

A) Online analyzers have advantages over traditional equipments, they requires less supervision and visits and can give more reliable informations. Online-analyzers are available in markets for early failure of treatment plants. AM200 On-Line Ammonia Analyzer, CT200 On-Lline UV COD Analyzer, NT200 On-Line Nitrate Analyzer, FL200 On-Line Fluorometer, CR200 On-Line Chromium VI Analyzer etc.

B) Three components are very important in waste water treatment plant. These are nitrate level, dissolved oxygen and ammonia in wastewater and these parameters are related to each other. It is very important to monitor their level and adjust while plant is running. Failure in this can result in high level of contamination into streams receiving wastewater. Along with this monitoring of total and reactive phosphorus, alkalinity and pH should also be considered.
