One of the top questions that I come across is, “Why don’t belt scales work well on sludge conveyors when it’s not the fault of the scale?”
As most wastewater plants are affected by sludge, they generally want to know the following:
When installing a belt scale on a conveyor in a wastewater plant, the conveyors are built to the same standards as a conveyor that is conveying sand or rock. Sludge is vastly different so the conveyors are unable to perform as well.
Here are some common reasons a scale may not work:
How can you overcome sludge issues with your conveyor?
There are a few solutions that you can implement to make sure your measurements are accurate. Here are some suggestions to overcome the problems outlined above:
The fourth solution, controlling the flow of sludge onto the belt, is a big one. If you are able to allow the sludge to slide onto the belt instead of falling on the belt, it makes a big difference on the loading and problematic splatter that comes off the discharge chute.
What solutions have you used in the past that have worked?
