DOMESTIC SEWAGE TREATMENT PLANT VS BIO-TOILET SYSTEM

how Domestic sewage treatment plant operates:

The domestic sewage treatment plant is an All-in-one device; a plant that has two or more compartment depending on the technology. all contained in a single enclosure. the station collects all the wastewater from the building and transports it first to the first compartment then to the settling tank which acts as a septic tank in the settling compartment , the solid waste settle and form sludge at the bottom of the tank.this compartment needs to be emptied regularly.

The waste water is sent to the reactor where it will be purified by the bacteria. A bacteria growth- support is placed in the middle of this second tank and the bacteria that grow there purify the water, to do this it is necessary to provide them with oxygen. the domestic sewage treatment plant must therefore be permanently supplied with electricity finally. the treated water arrives in the classifier where it undergoes a final settling stage. The sludge that forms in this tank is then reformed to the settling compartment.

advantages and disadvantages of domestic sewage treatment plant.

ADVANTAGES DISADVANTAGES
(1) The domestic treatment plant is the most compact and discrete device on the market. with only 5m2 of floor space it can be installed anywhere,even above ground in houses without land or underground.The operating system; it must be constant power supply electricity to operate. the annual cost of electric consumption is very high
(2) Its installation is very easy: it is light and easy to to transport, it can be installed in a day or two days max.If there is no constant power supply for a long while, the domestic sewage treatment plant will stop working and will take several weeks to return to normal operation once the power is restored. the wastewater would be discharged into the environment without properly treated thereby causing havoc.
(3) The system is reliable , very efficient and above all very well guaranteed, it is also a very flexible device, since manufacturers offers many different sizes, options and materials enough to easily find the right one fit for you.The domestic treatment plant needs to be running steadily to be effective. it is generally quite sensitive to load variations; if you are away for more than 4 months or if the building is occupied by non regular occupant that stay few times there. this will be a problem.
(4) Its installation cost is slightly lower than other wastewater treatment solutions on the market.Two building in a compound cannot shear one domestic treatment plant which is huge cost to installed two.

how Bio-toilet system operates:

Bio-toilet contains two parts in the structure. the toilet and Bio-digestion toilet.

The toilet drain is connected with decomposition tank using ceramic or steel to make the toilet which can be a water closet or a squatting pan. The bio-digestion tank devided into multiple sections to process the human waste in different stages. the decomposing tank will have three output values. one is to remove the fouls smell, another one is to decompose gas like Methane and another one is to remove water. once the human waste reaches the bio-digestion tank, the Anaerobic bacteria present in the bio-digestion tank start to bio-digest the human waste.These anaerobic materials can withstand a long range of temperature from 5 degree Celsius to 80 degree Celsius. these anaerobic batteries decompose the human waste into Methane and water. The Methane gas is sent through the vent, and the water can be treated for re-cycling usage. The Methane gas can be stored to use in the kitchen stove or used in the Methane generator to produce the Electricity. These bio- toilets can be installed anywhere without a big septic tank or sewage facility.

advantages and disadvantages of bio-toilet system.

ADVANTAGES DISADVANTAGES
(1) bio- digester toilet does not get filled; so there is no need to spend money on evacuation or dislodging
(2) bio-toilet is Odorless; you will not perceive foul smell.High cost of logistics for bacteria transportation
(3) It required small land to build, about (2m2 to 3m2).
(4) Bio- toilets does not depend on power supply to function on like domestic sewage treatment plant.
(5) Bio- toilet has high effluent quality.
(6) Bio- toilet is 99% aerobic treatment
(7) It does not required Maintenance
(8) It can last up-to the life span of the building.
(9) It is good for water logged or swampy areas.
(10) Bio-toilet system does not consume water to flush, just about half liter of water to flush.

IN CONCLUSION

Bio -toilet has many advantages over domestic sewage treatment plant, its more cheaper to run and maintained and environmental friendly. above all it does not require power supply to function unlike domestic sewage treatment plant, that alone is a huge plus.
