Operation of Wastewater Treatment Works
I am monitoring a 2ml of treatment works for a population of 19,500.
New growth is still continuing.
At peak hours flow increases 3 times the design capacity and treatment works operate with two process controllers.
At night no process controller is on-site and when is raining the WWTWs is overflowing, whereby screening is full of waste. Due to budget constraints we can not appoint extra process controllers.
In my case i have got some suggestion, and i need some advice too:
- I suggest to add a buffer/balancing tank, whereby flow it can overflow in it when is raining or absent of process controller.
- Add some bypass line to Primary settling tank, to avoid overflow in the inlet.
Your feedback much appreciated!
