<p>A reusable sewage water treatment system comprising a digesting chamber wherein waste coming from the household are deposited, anaerobic bacteria is contained within this digesting chamber as the biological medium of decomposition to reduce the biological oxygen demand (BOD) of the sewage water to acceptable level, a leaching chamber wherein all liquid overflow from the digesting chamber shall be routed thru an overflow pipe where further reduction of BOD is expected, an overflow pipe delivering the water from the leaching chamber to the tertiary raw tank, said tertiary raw tank acts as a clarifier tank wherein sludge settles to further pull down the BOD to a lower range, a chlorinator tank supplying small amount of chlorine on the raw tank so that pollutant materials can be quickly and efficiently removed in the tertiary raw tank, a tertiary filter tank wherein from the tertiary raw water tank, raw water is pumped thru a series of pumps, said tertiary filter tank is designed to remove the suspended solid on the tertiary raw water tank using filters, a pressure tank wherein the filtered water from the tertiary filter tank is pumped thru a pump where the filtered water is pressurized and a water line on the pressure tank where non-potable water is discharged out.</p> |
