Unblock a discharge pipe over several km
Have you done a cost analysis of replacing the pipe vs. cleaning it. I would recommend the former.
I misspoke: the discharge pipe was blocked in only one spot, but it is impossible to pinpoint since the pipe was closed and under pressure. Changing the pipe is not a short-term option—it requires significant investment and is the responsibility of the municipality.
So, in the meantime we have managed to unblock by digging trenches. The problem is that this pipe does not have a suitable self-cleaning flow, so we are looking for a biological solution. Is there a product you can recommend?
To ensure adequate self-cleaning speed, you need to boost pump power; that will help prevent clogging or at least delay it.
We have succeeded in unblocking a DN 200 discharge pipe by renting thermic pumps from Godwin (Xylem). You should calculate self-cleaning of at least 3ft/s. The advantage is that you can vary the speed of these pumps depending on your needs.
In our case, we went from 120USgpm up to 400USgpm.
Hello, I know of a world class product that works on the principle of magnetic homogeneity, it requires no external power and is life long. Need not to cut in the line and is installed around the pipeline of any material or diameter.
Not only softens and removes the clogged pipes but also prevent clogging in future.
