Abstract: A production method for biomass-alcohol includes a saccharification step of saccharifying biomass, a first concentrating step of ultrasonically vibrating the saccharified solution and atomizing the saccharified solution into a mist, so as to elevate the sugar concentration in the saccharified solution by removing water from the saccharified solution, a fermentation step of fermenting the saccharified solution concentrated in the first concentrating step to form an alcohol water solution, and second concentrating step of separating alcohol from the alcohol water solution fermented in the fermentation step.

Abstract: A water-treatment membrane module with raw-water manifolds connected in common to both end portions of spiral membrane modules and allowing raw water to flow in or out of the spiral membrane modules, in which each of the manifolds comprises a box and cover which may be opened for inspection and access to a treated water manifold in fluid communication with the water collecting pipes.
