A modular integrated plant system having has a liquid receiver (2) with a dosing element (3) comprising two holes, respectively, one for the passage of an air feeding tube (5) to the receiver (2) and another (6) for discharge of liquid from the receiver (2) under the action of gravity. A watertight platform (4) contains liquid from the receiver. Water flows from the receiver (2) due to a difference in height between the feeding tube (5) and the discharge tube (6), only if the water level in platform (4) is lower than the length of tube (5). An absorbing cloth is at the bottom of the component (4). A drainage means (9) removes the excess water from the platform (4), and aerating means (10) for the platform (4) has of holes positioned above the water line.
