Sewage sludge treatments describe the procedures used to dispose and manage sewage which is produced during the treatment. The sludge is composed mostly of water and have small contents of solid remove from the liquid sewages. Primarily it includes settle able solids that was removed during the first treatment clarifiers. The secondary is separated in second type of clarifiers that include treated sewage from the second treatment bioreactors. When it comes with chemical tank sludge, individuals can use the chemicals to remove mud away from the tanks.
There are many treatment procedures to remove the muds. Thickening is the primary step for the treatments. The mud from the first and secondary clarifiers will be stirred to form a bigger, more rapid settling aggregates. This will thicken it out about eight to ten percent more solid and the second part will also be more thickened for at least for percent solids.
The aerobic digestion is being achieved by using jet aerators or diffuser systems to oxidize the muds. Fine bubble diffusers are more cost efficient and power saving. The problem with plugging is that it owns a setting of small air holes. The coarse bubble diffuser is widely used in flocculation stages and sludge containers and tanks. It would be wise to select a diffuser that can ensure it produces the required oxygen rate of transfer.
Composting is another method of aerobic. This method will mix the sewage sludge with agricultural by products which are carbon like wood chips, straws, or sawdust. With the presence of air and oxygen, bacteria will digest both plant materials and sewage sludge to generate the necessary heat that will kill any disease causing parasites and microorganisms.
The filtration will occur in the under drains located in a sand drying bed or separated with a belt press called mechanical processing. The filtrate will likely return to the procedure. After dewatering it, it will be handled like a solid but will contain fifty to seventy percentage of water. The dewatered muds that own a high content of moisture would be considered as solids.
The anaerobic type usually generates biogases that have a high probability of methane that is used to heat up tanks and run micro turbines and engines or other site processes. The generation of methane is the main advantage of anaerobic. But the procedure is a long time to complete and will take at least thirty days and high capital cost.
The procedure can be done in facility for sewage treatments or other locations. This will depend upon the owner of the company and where the wastewater will travel after the procedure. The process will also require a complete set of apparatuses and technologies to fully control the flow of operation.
Another method for dewatering streams is also called phosphorus recovery. The advantage of this process is it reduced any forms or formations of any obstructive scales in valves, pumps and pipes. The obstructions will have a maintenance to remove the plants and the phosphorus content in the procedure will become elevated.
When the liquid is still being produced, it will require more treatments. The sludge will have to be thickened and dewatered in order to reduce their weights on transporting it. This will make the disposal much easier and faster.
