[Digestion] Digestion Digest, Vol 6, Issue 17

[Choppalli Venkata Krishna]

There are some 'Janata Model' Fixed Dome digesters in India - these were installed in 198 in India under the National Programme on Biogas Development.. In '86, Deenbandhu Fixed Dome model took over from  over Janata Model for its multi advantages over Janata. Still a good percent of these plants are functional. Functionality depends on after installation care, regular feeding and any other that can make the plant functional. Ofcourse prime conditions for longivity of any digester are - Quality of building materials, Skill of construction. and proper CURING. The toilets in Indian villages are connected to the inlet side of the digester if a pre concieved toilet jointing is there; if the cocept is later than the digester constrution, the toilet's out let is fed/connected to the Inlet tank of the Digester with a top cover to prevent possible odour of fresh excreta.-CVKrishnaIndiaOn Mon, 28 Feb 2011 03:16:03 +0530 digestion-request at lists.bioenergylists.org wrote>Send Digestion mailing list submissions to>digestion at lists.bioenergylists.org>>To subscribe or unsubscribe via the World Wide Web, visit>http://lists.bioenergylists.org/mailman/listinfo/digestion_lists.bioenergylists.org>>or, via email, send a message with subject or body 'help' to>digestion-request at lists.bioenergylists.org>>You can reach the person managing the list at>digestion-owner at lists.bioenergylists.org>>When replying, please edit your Subject line so it is more specific>than "Re: Contents of Digestion digest...">>>Today's Topics:>> 1.
