Phase I – Sedimentation

Septic tanks are used where public sewage systems are not offered, and also usually contain four elements: (1) a pipeline from the home to the septic tank, (2) the tank itself (more recent systems in Georgia are called for to have a two-chamber tank), (3) the leach or absorption field, and (4) the ground into which the wastewater at some point drains. A regular system utilizes gravitational force to move the wastewater through the system; however, sometimes a pump could be needed to relocate the wastewater from the tank to the absorption area.  For a more complete explanation, a plumber in the Athens area can provide you with up-to-date information as to the specifics of the local health code.

These 4 parts make use of 2 primary procedures to treat the wastewater: sedimentation and also soil purification. This article will address the first part of the process, namely sedimentation.  The other part will be discussed in the following article.

During the first sedimentation stage of the procedure all waste products from a residence’s plumbing system (all sinks, bath tubs, showers, commodes, washers, etc.) moves with a big pipeline which empties into the septic tank. The main objective of the tank is to enable the splitting up of the solids from the liquids. Over a duration of 24 hours approximately, any type of solid matter will certainly fall to the bottom of the tank where it is collected as sludge and also will be partly disolved by microorganisms in the wastewater. The fluid wastewater, described as effluent, builds up above the sludge. Any type of oils or oil will certainly rise to the top and produce a layer of scum on top of the sludge. A sewage-disposal tank will commonly house baffles to maintain the sludge as well as the scum from leaving the tank. (In the more recent two-chamber tanks, there is a position that enables the effluent to move into the second chamber, where more settling takes place separating more solids from the wastewater).
