Statistics estimate that the global population will be over nine billion people in 2050. This astounding number accompanies more pollution to air, water and soil – all which are vital for life on this beautiful planet called earth. The World Health Organization (WHO) has reported that roughly seven million people die each year from the air they breathe. While around 70% of industrial waste gets dumped into vital water sources. Can we decrease our pollution status by bioremediation?
What is bioremediation?
Bioremediation is the treatment of pollutants or waste (as in oil spills, contaminated groundwater, or industrial processes) by the use of microorganisms (such as bacteria). The two types of microorganisms – aerobic and anaerobic, use the pollutants or waste as an energy source, thereby breaking them down. There are three different bioremediation techniques, depending on the element needing cleaning. Biofiltration of the air. In situ land treatment for soil. Bioreactors for water treatment.
Volatile organic compounds which are by-products of industrial processes, pollute the air we breathe. Biofiltration uses a bioreactor which has culture media containing microorganisms. The microorganisms degrade contaminates into products such as carbon dioxide, water or salts.
WHO estimates that around 2.6 billion people worldwide lack any sanitation. Raw sewage contains some of the following components: suspended solids, organic matter, nitrogen and phosphorus. Water bioremediation is a method for cleaning polluted water. It works by aerating the wastewater in a treatment plant, thus providing the microorganisms with oxygen. They then degrade the organic material and pollutants, leaving behind clean water.
Soil can become polluted by processes that alter the natural soil environment, such as industrial processes. In situ bioremediation for soil pollution can involve several techniques. The first, biosparging, is the addition of pressurized air below the water table. The process increases groundwater oxygen concentrations and enhances the rate of biological degradation by providing an aerobic environment for the microorganisms. The second, bioaugmentation, is the introduction of microorganisms to the soil to ensure degradation of the contaminants such as tetrachloroethylene and trichloroethylene.
