Septic tank

From ArticleWorld

A Septic Tank is a part of a septic system, which is formed of a tank and a septic drain field. The tank will be filled with wastewater and the solids present in it will settle. After that an anaerobic digestion will be noticed, reducing the quantity of solids present. This process gives the installation its name. The liquid that is extra will be drained through a pipe system and will be taken to a leach field. All impurities that are still present in the water will decompose with time and water will be absorbed by the soil. Based on the amount of wastewater that needs to be filtered the rest of the septic system is built. Around 25% of the population of USA uses this method for wastewater disposal. Most areas are rural and with a city evolving and expanding the need of another system constantly rises.

Imhoff Tank

Another component that can be included in a septic system is the Imhoff Tank. It is actually an enhancement of the infrastructure that makes it possible for the sludge to be digested in another tank. The system is better because it allows the older wastewater to not mix with a newer one.

Cleaning

A septic tank needs to be cleaned after some time. This is because the residue found on the lower part of it can not be completely disintegrated by the anaerobe process. Failure to clean the installation will make the wastewater drain directly in the drainage field. The effect on the environment would be big and repairs on the septic system installation would be expensive. The time needed between cleanings differs from one period to the other, based on many factors including wastewater composition and even temperature.
