What is the aerobic system?
septic systems used to treat households and other waste water usually use bacteria to help process waste into the final product to dispose of the waste water. Anaerobic systems include bacteria that do not require oxygen to process waste. However, oxygen is required in the aerobic system. Usually, they must be drawn into the system to ensure that bacteria are able to process waste. Aerobic systems have some disadvantages compared to anaerobic systems, but under certain circumstances they are more suitable for use. Such bacteria use oxygen and waste drawn into the retention tank as a source of energy for their survival and growth. This results in waste decomposition and reduce the concentration of harmful microorganisms in the final liquid waste product. There are three basic types of aerobic treatment system (ATS): a system of suspended growth, sequential dose and reactor with fixed film.
bacteria float on the main tank in the system of suspended growth. The air draws themn in liquid waste. The treated solid waste settles in the secondary tank and the bacteria are cycled back to the main tank. The treated liquid waste is then discarded from ATS. Maintaining the correct balance of waste, waste water and bacteria is important to prevent clogging of the suspended growth system.
sequential dose reactor is a similar system of suspended growth in that bacteria float freely throughout the tank. However, decomposition and settlement takes place in only one tank. The air is supplied to this single tank only during the decomposition phase. During the settlement phase, it turns off to set the solids on the bottom of the tank. The drain is then exhausted from the tank, which completes the cycle.
While bacteria loosely float two types of systems, bacteria in a solid film reactor are connected to a specific surface. The decomposition takes place in one tank and the settlement takes place in the second tank. Air is supplied by a bondfrom the area of the decomposition tank with the surface to which the bacteria are attached. Recirculation of bacteria back into the tank of decomposition is not necessary because the bacteria always remain attached to the surface on which they grow.
Theaerobic system of any of these types is usually more expensive than the traditional anaerobic system in terms of initial costs and maintenance. Such systems usually have suggestions that are more complex and include more moving parts than traditional systems. They require electricity for the circulating air system during the decomposition phase, so they also require continuous operating costs.
Despite the higher costs associated with such a system, the aerobic system can be the most suitable, or perhaps the possibility of the possibility under certain circumstances. The production of higher quality waste water makes such a system suitable for sensitive areas of the environment. Space limitation may also require an aerobic system where a large drainage field would not be possible.
Some places do not allow the use of aerobic system due to VLAcquisition codes and regulations. Others allow the use of the aerobic system, but require the owner to have a contract with a professional to ensure proper maintenance of the system. Alarms may be required in some areas to warn the owner in the event of a system failure. Codes and regulations for installation and maintenance of the aerobic system are usually administered by state or local agencies such as the medical department.
