  • Patent number: 10611651
    Abstract: An electrode module including electrode plates spaced from one another by spacing means, a plurality of support members each extending through each electrode plate and at least one spacing means between two adjacent electrode plates for releasable securing of the electrode plates together, and each electrode plate includes a plate portion. Each electrode plate includes one supporting and connection lug portion configured to support each electrode plate at a first busbar or a second busbar in an electrochemical reactor for electrically connecting each electrode plate of the electrode module with a first busbar or a second busbar for supplying electrical current between one of the first busbar and the second busbar and each electrode plate of the electrode module.

  • Patent number: 10604427
    Abstract: A water treatment apparatus includes an electrochemical reactor including a shell structure and a support structure for supporting the shell structure on a base. The support structure includes at least one support element supporting the shell structure from the ledge. A head room portion includes, within the inner space of the shell structure, at least one shelf for receiving and supporting at least one lug portion of at least one electrode plate for suspending the electrode plate. The shelf being located, when in use, preferably directly above the ledge.

  • Patent number: 10329173
    Abstract: A system for treating water includes an electrochemical water treatment unit having a first self-supporting framework limiting a first inner space. An electrochemical reactor is arranged in the first inner space vertically below a first opening at a top side of the electrochemical water treatment unit. The system includes a maintenance unit having a second self-supporting framework limiting a second inner space. The maintenance unit includes a second opening in a bottom side. The maintenance unit is arranged above the electrochemical water treatment unit so that the first opening and the second opening are aligned. A hoist is moveably arranged along a rail structure at the top side of the maintenance unit.

  • Patent number: 10287181
    Abstract: An electrochemical reactor for electrochemically treating water, including a shell structure defining an inner space. The shell structure further includes an inlet portion having an inlet for conducting a water flow to the inner space, and a reactor chamber in flow connection with the inlet portion, and preferably with an outlet portion. The inlet is arranged such that the water flow to the inner space is directed away from the reactor chamber so as to cause the water flow to mix by forcing the water flow to change direction before entering the reactor chamber. A water treatment apparatus having such a reactor, and the use of such a reactor are also disclosed.

  • Patent number: 10166550
    Abstract: A flotation plant includes a tank module which includes a self-supporting framework having an inner space. The tank module includes at least one flotation tank. The flotation tank is disposed in the inner space of the self-supporting framework. The tank module is a self-supporting unit capable of being transferable and hoistable as an integral entity. The flotation plant includes at least two drive units for the rotation of drive shafts, each drive shaft being connected to a rotor for mixing and/or forming bubbles in the flotation tank. An overflow receptacle is disposed at the level of the upper part of the tank module for receiving an overflow from the flotation tanks. The flotation plant includes an overflow channel which is connected to the overflow receptacle for receiving and conducting the overflow from the overflow receptacle to a pumping means. The overflow channel is disposed outside the tank module.

  • Patent number: 10137460
    Abstract: A drive module which is a self-supporting structure being transferable and hoistable as an integral entity. The drive module includes a self-supporting framework having a shape of a rectangular parallelepiped. The self-supporting framework defines an inner space within the self-supporting framework. The drive module also includes at least two drive units. The drive units are supported to the self-supporting framework in the inner space of the self-supporting framework. The drive units are connectable to an external rotatable shaft for the rotation of the rotatable shaft located outside the drive module.
