Waste Disposal - General Waste Disposal Site
In final disposal sites for general waste, bentonite is used as the clay material of the low-permeable layer in the seepage control work for the bottom of the landfill sites.
In designing a low-permeable layer, soil present in the site is mixed homogeneously with quality sodium-type bentonite, and the mixed soil is laid on the bottom and slope and compacted by a compaction roller to form an impermeable layer.
Soil mixed with bentonite is prepared in the site. Soil present in the site is combined with bentonite at a given ratio (to have a given water content).
If crushed stone of bentonite obtained by crushing raw ores of bentonite to a given grain size is used as a low-permeable layer, it need not be mixed with soil present in the site, but can be directly laid and compacted by a compaction roller to form an impermeable layer.
The combination ratio of bentonite to soil present in the site is determined based on the results of laboratory combination tests or on-site test construction before combination.
The combination ratio of bentonite in soil mixed with bentonite in the site can be measured based on the viscosity of the mixed soil and controlled on-site.
