ENBIOLET TECHNOLO

GYENBIOLET-the Environment Friendly Aerobic Bio-toilet.

ENBIOLET……..WORKING PRINCIPLE:ENBIOLET is a Biological toilet system in which the Human Waste, the fecal matter is converted into non toxic neutral water and traces of CO2 within a purposefully built patented bio digester tank by the action of multi strain aerobic bacterial culture. The water thus generated is disinfected before it leaves the bio-digester tank and reaches the environment.

UNIQUENESS OF AEROBIC BIO-TOILET: 100% treatment of solid human waste, as per SBM guidelines 2014; Odor free and does not produce any foul smell; Completely Environment & user friendly as it does not emits Methane & Hydrogen

sulphide gas; Uses multi strain aerobic bacterial culture to clean human waste; Water positive solution as it generates neutral water; Prevents soil pollution from open feces discharge; Preserves ground water quality caused by leaching of human waste; Controls the spread of fecal transmitted diseases: diarrhea , amoebic dysentery,

cholera, etc.

COMPOSITION OF HUMAN FECAL MATTER

Utilized by bacteria to obtain energy: C+O2 CO2+ energy

2H+1/2O2 H2O + energy

CO2(Traces) & H2O released

Utilized by bacteria: Nitrogen forms major component of DNA of new forming bacteria; P, Ca & Sulphur are

used as micronutrients

THE TECHNOLOGY: Bacteria, like all living things, require food for growth. Human solid waste provides a good source of readily available food to them. Aerobic bacteria digests the solid waste containing organic matter like carbon, nitrogen, hydrogen, etc for obtaining energy. The end product of the process is carbon dioxide (CO2) and water (H2O).

THE BIO-DIGESTOR TANK:

TECHNICAL FEATURES OF BIO-MEDIA:

Multi strain bacterial mixture; Consists of aerobic & facultative bacteria's: able to grow under aerobic

(presence of O2) as well as anaerobic (absence of O2)conditions but mostly prefer to grow rapidly in an aerobic environment;

Aerobic respiration generates more energy (in form of ATPs) as compared to anaerobic respiration;

Can form endospore in stressed condition and revive to vegetative state on getting favorable environmental condition(food, water, O2)

Endospore can survive up to 2 years under controlled condition;

BIO TOILETS

TYPES

THERE ARE BASICALLY TWO TYPES OF BIO TOILETS BASED ON TECHNOLOGY USAGE: 1.Aerobic Bio-Toilet: involves the aerobic bacteria which feeds upon the fecal matter inside the tank, under aerobic bio digestion process and finally degrades the matter into neutral water and traces of CO2. 

2.Anaerobic Bio-Toilet: involves the anaerobic bacteria which feeds upon the fecal matter inside the tank, through an anaerobic process which finally releases methane gas and treated water. 

AEROBIC BIO

TOILETSADVANTAGES

Aerobic bio-toilets uses multi strain aerobic bacterial culture where as anaerobic biological toilet uses single strain bacteria culture.

Anaerobic bio digestion is extremely slow process while aerobic digestion completes within 24hours;

Aerobic bio digestion generates neutral water & only traces of CO2. Anaerobic bio digestion generates large volumes of Methane, which is a greenhouse gas and emission is banned globally.

Anaerobic bio digestion generates huge volumes of sludge as digestion is not complete while no sludge remains from aerobic bio digestion;

Aerobic Bio toilets require a very small volume of bacterial culture for charging while half of the tank of anaerobic bio toilet needs to be filled with bacteria.

Aerobic Bio digester tank size is nearly half in size of Anaerobic tank. Aerobic bacteria is freely available in nature; easy to propagate and store.

DIFFERENCES BETWEEN AEROBIC BIOTOILET AND SEPTIC TANK SYSTEM:

SL.NO SEPTIC TANK SYSTEM AEROBIC BIOTOILET

1. The wastes in the septic tank are not digested and it seeps into the ground; may contaminate ground water leading to an epidemic.

The wastes from the toilet are digested by the bio media resulting in neutral water and gas.

2. Large floor area required almost twice that of the Bio digester tank

Less floor space required as the Bio digester tank is small in size.

3. Septic tank requires excavation, cementing, curing, partitioning, etc. So, it is a labour intensive and time consuming process and installation is slow. Its permanent structure.

The Bio digester tank can be placed on the ground, so no digging or foundation required, so installation is fast and also portable in nature.

4. This system requires periodic sludge removal which may lead to waste spillage on the ground resulting in unhygienic conditions and diseases.

This system requires less maintenance and does not require periodic sludge removal as the wastes are converted into water.

DIFFERENCES BETWEEN AEROBIC BIOTOILET AND LEACH PIT SYSTEM:

SL.NO LEACH PIT SYSTEM AEROBIC BIOTOILET

1. A large ground area is required to construct a Pit away from the toilet;

Very little ground area is required, as there is a single Bio digester Tank, which is constructed below the toilet room;

2. Needs to be evacuated every three years and there are chances of overflow.

Does not need evacuation as the solid wastes are converted to water;

3. A pit once filled up requires a rest period of 2-3 years before it can be desludged; a new pit have to be dug again-wastage of land and resources ;

No rest period is required in EnbioletTM, as the digestion process is a continuous ongoing process and starts in 3 hours

4. The sludge has to be removed manually or mechanically, which may come in contact with the people handling the waste, it is unhygienic and may cause diseases.

No sludge removal, so no chances of people coming in contact with wastes. So it is much more hygienic and safe.

5. To prevent pollution of drinking water sources, the pit should be 3 to 10 meters from the water source. This is a health hazard and requires idle stretches of land.

No chances of pollution of drinking water sources from the Bio digester Tank, as the effluent is non contaminating and non pathogenic.

DIFFERENCES BETWEEN AEROBIC BIOTOILET AND COMPOSTING TOILETS:

SL.NO COMPOSTING TOILETS AEROBIC BIOTOILET

1. Originally conceived as waterless systems, composting toilets have no water seal incorporated and have been reported to have foul odour and flies;

All Enbiolet installations are water-sealed and therefore effectively control the spread of odour and vectors

2. Composting toilets have effluent accumulation at the base of the unit in the evaporation chamber which is often a mix of both fecal sludge and bulking materials releasing foul odour;

As a sealed system, the water-seal and vent pipe integrated into the design of the tank of most units control the passage of flies and insects and controls odour.

3. Wastewater overflows outside the compost tray; No overflow of liquid occurs. The effluent water originates after the solids undergo bacterial digestion in the first chamber and gets discharged from last chamber.

4. Users are required to pour bulking material after each defecation, rotate the handle & monitor daily.Its difficult to handle rotation, frequent emptying and user numbers is limited to 1-4 people.

Regular cleaning and periodic maintenance is required for Enbiolet, especially weekly Bio-media charging & fortnight disinfection. User no. ranges from 20-30 times usage per day

5. It is suggested for compost removal at the end of 6 months of regular use but rapid filling up of drum contents and liquid overflow outside the digester in less than 2 months, leads to the emptying/cleaning of drum contents rapidly;

Enbiolet technology is free of producing compost and promotes solid waste reduction.
