BIO – DIGESTER

SINTEX MAKE BI0 – DIGESTER

The Sintex Bio – Digester Technology is a cleantechnology that does not pollute ground water andthe effluent is water, CO2 and Methane gas. Theeffluent water is enriched with minerals that isodorless, colorless, and free of pathogens and canbe used for gardening or recycled for flushing. Italso does not require any electricity and thedigestion takes place in an anaerobic environmentand in a sealed container due to bacterial activity.There is no sedimentation and therefor the tankdoes not require evacuation at all. As the effluentwater is safe it can be used safely where there is nosewerage or drainage system.

WHY SHOULD AVOID SEPTIC TANK ? ➢ The Septic tank is a device commonly used in areas

with no connection to main sewage pipes provided bylocal governments or private corporations. The term“Septic” refers to the anaerobic bacterial environmentthat develops in the tank which decomposes ormineralizes the waste discharged into the tank.

➢ The main problem with septic tank is that bacterialfermentation of the waste is not complete as theprocess is neither completely aerobic nor completelyanaerobic. In such situation, only facultative type ofbacteria do the job resulting into large quantity ofsludge and H2S gas which is foul smelling. Sludgehas to be removed which smells badly at the place ofdisposal.

WHAT IS BIO – DIGESTER ? ➢ To overcome the problems of septic tank, bio –

digester technology have been developed whichemploys anaerobic microbial consortium thatperorms fermentation underanaerobic conditionsin anoxic environment provide in the tank. Beingcompletely anaerobic process the process oforganic matter biodegradation is almost complete(99%) and there is hardly any sludge generationof H2S production.

➢ The bio – digester is readymade device(Fermenter) made of mild LDPE. This is a closedcontainer and only treated effluent comes out ofthe outlet besides biogas coming out of the gaspipe.

CONSTRUCTION OF BIO – DIGESTER

It is composed of 2 components – (i) theanaerobic microbial consortium which isformulated from group of bacteria that are veryefficient to perform the bio – degradation of thehuman waste in wide range of temperature andin presence of toxic chemicals. (ii) The vessel inwhich fermentation is carried out with the helpof bacteria is called bio – digester.

There are following advantages of Bio – digester technology over conventional septic tanks :

I. Space Requirement :- Size of Bio – digester for fixed number of users is lowerthan the size of conventional septic tanks, so they can be installed inspace constrained areas also tank

II. Cost : The installation cost of Biodigester will always be lower thanconventional tank (Please refer table above). Further Biodigester doesnot require any cleaning hence there is no recurring cost as againstseptic tank.

III. Quality of Effluent: Effluent quality of Biodigester is much better thanthe conventional septic tank in terms of BOD, CO, Colour,Pathogenicity, Smell etc.

IV. Use of Toilet cleaning agents: Use of cleaning agents (In justifiedquantity ) is permitted in Biodigester but not recommended in septictank

V. Effluent Gas: The gas coming out of septic tank is mainly CO2 andH2S whereas from Biodigester is biogas composed of mainly CO2 andMethane., The biogas can be used as energy source whereas gas ofseptic tank foul smells and only adds to the pollution.

VI. Installation: The Biodigester can be installed in any geo-climaticlocations in the county where as septic tank has a limitation for placeof installation.

VII. Eco-friendly: The discharge from the septic tank (gas, sludge andliquid) adds to the environmental pollution as waste material,whereas effluent liquid and gas from Biodigester can be used forirrigation and energy purposes, respectively.

VIII. Maintenance: The biodigesters once installed do not requirecleaning or any other maintenance whereas septic tanks requireregular cleaning which in most of the cases is manual and unethical.
