EFFLUENT DISINFECTION SYSTEM FOR SEPTIC TANK DISCHARGE

Background Type design of Effluent Treatment System Chamber has been prepared for use with the Septic Tank where the effluent is being discharged untreated into open drains, sewers, nalas or anywhere around. It is believed that the Septic Tank discharge dropped as above is quite offensive and is likely to reach some water body or river. It is therefore proposed to do the treatment of this effluent before being discharged into open drains. Construction and Fittings The diagram shows a chamber which receives effluent from Septic Tank. This effluent will be carried to the bottom through a down pipe as shown in the figure. There will be an aluminium Screen (JALI) 50 cm above the bottom (floor) of the chamber. This space will allow settlement of sludge and heavy particles in the bottom upto a level of 50 cm height. A diffuser plate will be placed on this Screen (Jali), which will be connected to the OZONATOR machine outside the chamber, preferably mounted on a wall. A small vertical centrifugal water pump is also placed on other side of this aluminium Screen (JALI). This pump is capable of drawing liquid effluent from the Screen (JALI) base bottom where it is placed to pump the liquid effluent into the UV tube chamber. From UV tube chamber the effluent water drops into this chamber itself after being exposed to UV rays. As this process of pumping continues the .liquid effluent in the chamber will pass through the UV tube chamber repeatedly a number of times before overflowing through the outlet tube to reach outside drain. As the ozonater will also be working simultaneously the liquid will be continuously subjected to ozonation which is the advanced form of oxidation. The UV exposure and the oxidation as explained above is capable of ensuring disinfection of the Septic Tank Effluent before it is discharged into drains. The above structure and the process of disinfection of Septic Tank effluents the applicant's original work and is therefore requested to be patented. It is to be known as Effluent Treatment System for Septic Tank Discharge. (ETS-STD)
