Controlling The Odour Of Waste And Refuse
There are several types of bioremediation technology. One in situ technology is bioventing. Bioventing involves breaking down organic components that are absorbed in the groundwater by through the use of microbes. By stirring up the airflow and adding necessary nutrients, bioventing will boost the activity of the local bacteria. Bioventing helps with the reduction of volatile organic compounds and absorbed fuel. Another technology is land farming. Land farming is used in the upper soil zone. Polluted soil and sediment is integrated into the surface of the soil and occasionally tilled in order to ventilate the mixture. Land farming uses equipment similar to those used in farming operations. These activities help in developing and improving the breakdown of harmful substances through the use of microbes. Composting is another technology. Composting at its most basic level is simply placing waste materials into a pile and waiting for approximately a year. Composting in an updated, systematic approach requires several steps. The entire process involves carefully measuring out amounts of water, air and materials enriched with nitrogen and carbon. It is further assisted by adding water and cut up plant life. The compost is frequently tilled to allow ventilation. Compost is useful as a fertilizer, a natural pesticide, and for soil conditioning as well as for use in landscaping, gardens, and horticulture. It can also be used to control erosion, to construct wetlands, as landfill cover, and for stream and land reclamation. Another technology is bioaugmentation. Bioaugmentation utilizes local microbe strains or genetically engineered alternatives to assist in treating contaminated water and soil. Generally used for public wastewater treatment, bioaugmentation resumes activated sludge bioreactors. Generally, activated sludge systems utilize microbes such as protozoa, bacteria, fungi, nematodes and rotifers able to break down biodegradable organic compounds. However, most available microbe cultures include all the essential microbes such as Flavobacterium, Arthrobacter, Pseudomonas, Steptomyces, and Triphoderma. Biostimulation is another technology used that involves changing the environment to encourage the bacteria that is already present. This is accomplished by adding carbon, oxygen, phosphorus, or nitrogen, and rate limiting nutrient to the subsurface. Lastly, rhizofiltration is another technique. It is a kind of phytoremediation. Rhizofiltration utilizes plant roots to remove toxins by filtering dirt and water. This can be accomplished in one of two ways. Plants can be planted around the contaminated site or the polluted water can be collected and taken to the plants.
