Hello,
I have two alternatives from which I need to choose:
First:
used backwash water shall be recirculated to the head of the water treatment
without any further treatment.
Second:
Designing a separate treatment for the used backwash water.
The water treatment includes coagulation & flocculation, sedimentation and filtration.
Can you please advise me why should I design a special side process for the used
backwash water? In any case, most of the side treatments include the same
processes as the main line.
Source of water is a river and capacity is pretty low (about 700 m3/hr)
Thanks,
David
Welcome to EE!
This question is way out of my knowledge realm...
I would first suggest that you research out any local od national regulations on how to design for water treatment. If no regulation are available I would suggest using the most likely to succeed design.
It is way easier to over engineer than to engineering it "just right"...
Good luck
Thank you
