The types of purification sludge generated in result of wastewater treatment facility procedures can have different properties. The elements determining the characteristic properties of these types of sludge is related to the water content. In addition, the utilized treatment process is also important in this regard.
The types of purification sludge have certain chemical, physical and biological properties. Physical properties of wastewater purification musts include the solid content of the sludge, as well as the odor and temperature of the must. In addition the color of the sludge is also another physical property.
When discussing chemical properties of the types of wastewater purification sludge, one of the important factors is the inorganic and organic matter content dissolved or suspended in the waste water. The most important feature of chemical parameters is the fact that they help indicate which function is the most suitable end use for a certain type of purification sludge. These parameters help decide whether a certain type of purification sludge is suitable for use for agricultural purposes. Another important data point for types of purification sludge is their biological characteristics. Various groups of organisms are found in purification sludge. In addition to bacteria, certain viruses, plants, algae and other microorganisms can be found in this sludge.
The importance of biological parameters in regard of the types of purification sludge is the fact that they provide data regarding whether these types of sludge can be safely used. Decisions on where to utilize such waste sludge can be made in light of said data. Whether certain types of purification sludge contains hazardous wastes must be determined before their disposal. Wastewater purification sludge is subject to various processed before disposal. One of these processes is biological sedimentation, while another application is known as chemical sedimentation. Biological and physical treatment methods are preferred for household wastewaters. On the other hand chemical treatment methods are more suitable for industrial wastewaters.
Wastewater Treatment Facilities:
Different processes are in question during operation of wastewater treatment facilities. The purification sludge generated in processes of wastewater treatment facilities also has to be subjected to certain procedures. Purification sludge is generated in result of processes performed on industrial and household wastes at the treatment facilities. Purification sludge contains various viruses, bacteria and heavy metals. In addition to hazardous materials, the purification sludge must also be processed in regard of microorganisms. This way the wastes are prevented from damaging the environment and posing a risk for human health.
Various methods are utilized for disposal of purification sludge, while this sludge can also be recovered for various fields of use. Since types of purification sludge have high thermal values they can be used as an energy source. Certain types of purification sludge can also be used as fertilizer in agricultural lands. The fact that they also show benefits on the soil itself is another reason for use of purification sludge in this fashion, in addition to plant development in agricultural lands.
