The diagram shows a SEPTIC TANK SYSTEM & How domestic waste passes through the system for basic treatment before draining away. x86Ew
The diagram illustrates a septic tank system and the process of filtering water before draining it away. Overall, the key role of the system is to separate the mixture of domestic waste into three layers solids (or sludge), effluent ( filtered wastewater or sewage) and scum. This treatment of wastewater consists of two main stages, starting when the sewage enters the first compartment and ending when outputting the water. The whole system comprises an underground chamber made of concrete with two compartments equipped with an inspection pipe on top one of each. Moreover, there is one manhole cover for urgent treatment, an inlet, transition and outlet baffle. In terms of basic primary treatment, once sewage enters the system through the input baffle, it will be held long enough that solids can settle to the bottom, where it will be decomposed by microorganisms, simultaneously forming a sludge layer and oils and greases to float on the top forming a scum layer. In the following stage, when the level of water is rising higher than the baffle, the residue of wastewater in the first compartment will be pushed out into the second chamber, where the whole process of treating and filtering wastewater will identically take place the second time in the parallel compartment. The previously treated water will be sieved again by the output baffle before dissolving into the drain field after the secondary partition reaches its maximum capacity.
