Non-resistive circulation to elevated containers

A system with fluid for circulating a fluid in a non-resistive manner to elevated position comprising a circulation unit comprising:

• at least one source container,
• at least one closed container, and
• at least one elevated container;
• wherein the system further comprises:
• at least one group of source conveyors for fluid circulation, operatively connected between the at least one source container and at least one closed container, and
• at least one group of extract conveyors for fluid circulation, operatively connected between the at least one closed container and the at least one elevated container,
• wherein each group of conveyors comprises
• at least one circulation circuit between at least one closed container and at least one elevated or source container, the at least one circulation circuit having a circulation input and a circulation output, and
• wherein the system is provided with
• circulation mechanisms, and
• start stop mechanisms,
• characterized in that the system achieves non-resistive circulation by circulating through one group of conveyors at a time, wherein the fluid level in the at least one elevated or source container for the circulation output is substantially equal to the fluid level in the at least one elevated or source container for the circulation input in the circulation circuit,
• wherein the circulation circuit is circulating an equal amount of fluid from the at least one elevated or source container, as it circulates to the at least one closed container.
