System for treating water

A system for treating water comprising:

• at least one electrochemical water treatment unit comprising a first self-supporting framework having an outer form of a cuboid and limiting a first inner space, wherein at least one electrochemical reactor is arranged in the first inner space, wherein the at least one electrochemical reactor comprises at least one electrode module releasably arranged in the at least one electrochemical reactor, wherein the at least one electrochemical water treatment unit comprises a top side, a bottom side disposed opposite to the top side, a pair of opposed end sides and a pair of opposed sides extending between the top side, bottom side, and opposed end sides, wherein the at least one electrochemical water treatment unit comprises a first opening in the top side, and wherein the at least one electrochemical reactor is arranged in the first inner space of the at least one electrochemical water treatment unit vertically below the first opening in the top side;
• a maintenance unit comprising a second self-supporting framework having an outer form of a cuboid and limiting a second inner space, wherein the maintenance unit comprises a top side, a bottom side disposed opposite to the top side, a pair of opposed end sides and a pair of opposed sides extending between the top side, bottom side, and opposed end sides, and wherein the maintenance unit comprises a second opening in the bottom side;
• the maintenance unit configured to be arranged above the at least one electrochemical water treatment unit so that the first opening in the top side of the at least one electrochemical water treatment unit and the second opening in the bottom side of the maintenance unit are aligned and so that a section of the maintenance unit is unsupported by the at least one electrochemical water treatment unit;
• a third opening in the bottom side in the section of the maintenance unit;
• and
• a hoist movably arranged along a rail structure at the top side of the maintenance unit in the second inner space of the maintenance unit, so that the hoist is movable to a position above the second opening in the bottom side of the maintenance unit and to a position above the third opening in the bottom side of the maintenance unit.
