LANDFILL ODOUR CONTROL
Dump sites are one of the most complicated waste handling sites because they consist of many forms of chemical and organic materials. The solid wastes are left on the dump sites for natural decomposition where mostly anaerobic activity occurs resulting in high levels of ammonia and hydrogen sulphide.
Although there are three methods of treating landfill odour, a biological approach is the most viable option.
BACTREAT-OE for treating landfill odour
- Using chemicals to stop bacterial degradation. If you kill all bacteria in the dump site, you stop biodegradation. There will be no biodegradation, hence no smell.
- Using perfume to mask the bad odour. This is feasible for small scale, but impossible for any large solid dumpsites.
- The most viable approach to landfill odour control is biological treatment. As stated above, dump site waste is very complex, you need very effective bacteria consortium with very good anaerobic and facultative strains that can work effectively.
The biological approach uses beneficial bacteria to help degrade the complex organic matters, in the process, helps to speed up the compaction, increase the holding capacity of the landfill. In the process, more ammonia and hydrogen sulphide are generated due to increase biological degradation.
