SEPTIC TANK
Septic tank is an essential part to conserve environmental balance. This is a tank or a collection of tank of between 5000 and 7000 liters in size. This is very common in those areas which are isolated from the direct connection of the main drainage system.
The term septic is derived for its facility available to decompose the bacterial growth. The discharge is treated well to neutralize all the bacterial growth and protect environmental pollution. This is done with the help of some anaerobic bacteria culture inside the tank. The working principle of septic tank is very simple. Disposed sewage enters the tank and sedimentation takes over here allowing solids to settle down. The solid is treated with those bacteria and this reduces the volume of the solids. The excess water after the remaining impurities are trapped is eliminated through percolation into the soil. The remaining solid waste should be periodically cleared off to increase the working efficiency of the tank.
As the septic tank is completely made to maintain the environmental factors so care should be taken to maintain complete ecological balance. This includes vegetation, microorganisms, soil, rocks, atmosphere and natural activities that is included or associated with the septic tank. Ecosystem which consist all biotic factors should be well maintained and should be taken under prior notice while manufacturing a septic tank. If the ecosystem is hampered every element constituting this environment is hampered. So it is important to be careful and aware.
As the above mentioned risk can highly affect the environment creating ecological imbalance same is true when sewage is not properly disposed. Sewage treatment is a process of removing all the impurities contaminants from the disposed water. Disposed water may contain various metals and other substances which are extremely harmful for the environment. The main objective of this process is to produce an environmentally safe fluid which will not affect the environment. Sewage is treated in a decentralized system like the septic tank. Now concentrating on the disinfection process it is always deep concern to reduce the number of microorganisms in the water to be discharged back into the environment. Treating the water with chlorine is one of the common processes. The odor produced in the septic tank is a smelly gases is treated with different chemical so that to reduce the smell.
Septic tank can have multiple effects on nutrients pH level of water. This affects the biological life in water. A properly designed and normal operating tank do not have odor. Various designs of septic tank are invented which can last for long years.
Few drawbacks are there such as cooking oils and grease causes the blockage of the inlet. A non biodegradable substance may clog the septic tank. Excessive water will overload the tank and so it is necessary to clear it up0 frequently. Septic tank if used with proper care is very useful for those who are very far away from the main drainage system but proper maintenance is essential.
