The present invention relates to a method for concentrating, with low energy, a solute-containing solution in a state of multiple-no osmotic pressure difference (M(multiple)−Δπ=0 RO), and, more specifically, to a method for concentrating, with low energy, an solute-containing solution intended to be concentrated, as a low pressure in a state of multiple-no osmotic pressure difference. The method for concentrating a solution containing a solute at a low pressure in a state of multiple-no osmotic pressure difference, of the present invention, consumes less energy, enables concentration to be performed until a saturated aqueous solution with a maximum solute concentration is obtained or the concentration of the solute becomes 100% even though an extraction solvent is not used, and does not require the use of an additional osmosis-inducing solution.

Method for concentrating aqueous solution with low energy by using reverse osmosis and forward osmosis in state in which multiple-no osmotic pressure difference is induced

A cargo transporting vehicle configured to travel along a path of a work site is provided. The cargo transporting vehicle includes: a traveling unit configured to travel on the path; a plate configured to load a cargo thereon; a loading unit including at least an articulated arm structure in which a width and an extendable length are adjusted according to dimensions of the cargo, the articulated arm structure being configured to load and unload the cargo onto and from the plate; and a plate lifting unit configured to raise or lower the plate.
