slide1. Conventional Methods for wet areas
Swamps, Marshes, tidal area and ponds are typical wet areas.
Special treatment is required to control the contamination of ground water.
In the past, the usual practice was to divide the area into cells, so that one cell is filled each year.
To withstand the mud moves and to increase structural stability dikes are used to divide the cell or lagoons.
More recently because of concern of the possibility of ground and
surface water contamination by both leachate and gases from L.F the direct filling is not acceptable.
Special provision must be used to contain or eliminate the movement of leachate and gases from completed L.F as follows:
Draining the site before using it for L.F.
Lining the bottom with clay liner.
Alterative operational plane
In addition to the conventional methods of L.F specialized method are being developed include :
The recycling of leachate to accelerate the rate of anaerobic decomposition.
The mixing of sewage sludge and S.W to accelerate an aerobic decomposition of the S.W, with the objective of capturing the conversion gases for uses in energy recovery system. 1<br>
slide2. If the gases produced from anaerobic decomposition of S.W are to be captured effectively, the use of deep, individual clay lined cells appears to be most effective. 2<br>
