Application: Disposal of Liquid Seepage at a Landfill
Problem: Many landfills are made up of a series of non-permeable cells used
to hold the fill. A separate semi-permeable barrier is positioned several
feet from the inner walls of the each cell allowing natural runoff
and rainwater to seep through the barrier and accumulate in the
bottom of the cell. The liquid seepage then has to be eliminated.
Solution:
AMETEK model 575F Intrinsically Safe Submersible Pressure Transmitter
A
Model 575 Intrinsically Safe Submersible
Transmitter and a meter/controller
are used to eliminate the liquid seepage.
The transmitter is positioned in the bottom
of the cell by means of a PVC pipe.
Both the transmitter and a local pump
are connected to the meter/controller.
The transmitter sends a signal representing
the level of liquid to the meter/
controller and, at the desired level, the
meter/controller activates the pump. The
pump then expels the liquid to a holding
tank for future treatment and disposal.
