The Task
Our client needed to separate the liquid flow generated by two
aerators within the same leachate treatment lagoon.
The Solution
F.L.I. Environmental proposed the use of a 2mm thickness HDPE
geomembrane baffle curtain suspended from a stainless steel cable
tensioned across the lagoon. The Geomembrane Baffle at the surface was
wrapped around the suspended from an HDPE pipe designed to carry the
stresses from the cable suspension.
At the lagoon base concrete anchor blocks placed on dense synthetic
rubber protection pads above the liner were used to secure the baffle
curtain base using a reinforced geomembrane/pipe design similar to
that used at the surface.
General
Baffles are often used in portable water reservoirs and water
treatment facilities to increase the flow path of liquid passing
through the system. This ensures that all of the liquid entering the
system is subject to similar treatment duration and that there is no
short cut between inlet and outlet and also no untreated stagnant
areas. |
