DJB using ISASMA-CD to treat water at STPs

The Delhi Jal Board (DJB) has developed the Intelligence Self-Admi­nis­tered Self Monitored Automatic Chemical Dosing technology to treat water at four sewage treatment plants (STPs) at Yamuna Vi­har and Okhla. The technology helps reduce the biological oxygen demand (BOD) and the total suspended solids (TSS) to less than 10 parts per million (PPM). The technology runs with an AI software and shares real-time data and monitors plant health. For the past four months, the 16 million gallons per day (mgd) Okhla plant has been recording 5 PPM BOD and 8 PPM TSS levels. Earlier, the TSS and BOD levels at the 25 mgd plant in Yamuna Vihar were 125 PPM and 90 PPM, which have now come down to 8 PPM and 7 PPM respectively.
