Abstract:
1. A method of modular construction of a methane digester facility comprising the steps of: placing a plurality of prefabricated portable concrete panels to form a pair of opposing side walls and a back wall connected to the side walls by corner concrete panels; placing a modular concrete angled front piece at a front end of each side wall to produce a sloped door inset piece; placing a row of headers on the side walls and the back walls; placing a plurality of footers in a row between the modular concrete angled front pieces, wherein troughs formed in the tops of the headers, the front pieces, and the footers form a continuous sealing channel around the top of the methane digester facility; and sealing an interior space of the methane digester using a flexible membrane roof having inflatable ends insertable into the continuous sealing channel.
