Grober Green

It was a beautiful day today, as the supporting beams for the ceiling on the digester tank were installed.  The sun was shining and not a cloud in sight for the better part of the day.  The supporting beams are solid pine pillars, and the ceiling is going to be made up of many planks of pine as well.  The ceiling is made out of wood because it will naturally absorb the unwanted sulfur byproduct of the digestion process.

Also in the past few days, the forms for the first ring of the new holding tank have been put up, as well as the structural re-bar for the walls.  Inside the digestion tank, tar was sprayed onto the uppermost ring.  This ring will be the only ring in contact with the gases, and so the tar will protect the wall from any wear and tear that would occur there.  The sand and rocks that washed into the trenchs around the digestion tank and F.O.G. tank were shoveled out and cleaned up to allow us to pick up the bentonite carpet and nail it to the walls of the tanks.  This allows for the future rain water to run away from the base of the tank rather than stay around the walls and foundation.

The forecast is showing more sun over the week, which means progress will not be delayed by pumping water out of the pits, and hopefully it stays that way.
