20 Jul 2022 CW Team

In a first, the Delhi Jal Board (DJB) has developed a technology to treat water in its sewage treatment plants. This technology, called ISASMA-CD (Intelligence Self-Administered Self Monitored Automatic Chemical Dosing), has been introduced at four DJB plants at Yamuna Vihar and Okhla with the objective of reducing biological oxygen demand (BOD) and total suspended solids (TSS) to less than 10 parts per million.

Running with AI software, the technology shares real time data and monitors the health of the plant as well as machine and equipment. The plants are totally automatic and Internet of Things (IoT)-based.

“The technology delivers a pictorial representation of the plants unit that are functioning which can be accessed on a web portal,” said a DJB official.

The Okhla plants have 16 million gallons per day and 45 MGD capacity, whereas the Yamuna Vihar plants have 25 MGD and 10 MGD capacity.

“All these four plants have been achieving their targets. On average, for the last four months, the 16 MGD Okhla plant has been recording 5 PPM BOD and 8 PPM TSS levels. These are well below the targeted values that DJB wants to achieve," the official added.
