Abstract:
An electrochemical reactor (1) for electrochemically treating water, comprising a shell structure (3) defining an inner space. Said shell structure further comprises an inlet portion (4) having an inlet for conducting a water flow to the inner space, and a reactor chamber (6) in flow connection with the inlet portion (4), and preferably with an outlet portion (5). The inlet is arranged such that the water flow to the inner space is directed away from the reactor chamber (6) so as to cause the water flow to mix by forcing the water flow to change direction before entering the reactor chamber (6). A water treatment apparatus having such a reactor, and the use of such a reactor are also disclosed.

The central shaft and the filter being rotatable around longitudinal axis of the central shaft. The filter apparatus further comprises an identification unit arranged to store an identification code specific for the filter element, a receiver apparatus comprising a receiver means arranged to receive wirelessly an identification signal comprising said identification code, and a forwarding means for forwarding an output signal based on said identification code.
Abstract:
The invention relates to a flotation tank module and its uses, a flotation plant, a method of changing of the flotation tank module, a method of replacing the self-supporting tank in the flotation tank module and a self-supporting tank. The flotation tank comprises a framework. The framework has a shape of a rectangular parallelepiped and comprises a framework bottom and framework sidewalls (3, 4). A self-supporting tank for receiving the liquid is placed inside the framework without being attached to the framework bottom and the framework sidewalls (3, 4).
Abstract:
A rotor (100) of a gas dispersion arrangement, comprising a cover disc (1), air slots (2) arranged to protrude away from the cover disc (1), the air slots (2) defining an interior space (3) in the interior of the rotor, an air channel (4) connected to the air slot (2) for supplying air to be dispensed in slurry, and slurry slots (5) arranged between and an alternating way with the air slots (2) around the interior space (3). The slurry slots (5) are in fluid communication with the interior space (3), and radially extending blades (6) arranged for separating the air slot (2) from adjacent slurry slots (5). The cover disc (1) comprises at least one through-hole (7) extending from an upper surface (8) of the cover disc to at least one of the slurry slots (5).
Abstract:
The invention relates to a system for treating water comprising an electrochemical water treatment unit (1) comprising a first self-supporting framework (2) limiting a first inner space (3). An electrochemical reactor (4) is arranged in the first inner space (3) vertically below a first opening (10) a top side (6) of the electrochemical water treatment unit (1). The system comprises also a maintenance unit (11) comprising second self-supporting framework (12) limiting a second inner space. The maintenance unit (11) comprising a second opening (13) in a bottom side (7). The maintenance unit (11) is arranged above the electrochemical water treatment unit (1) so that the first opening (10) and the second opening (13) are aligned. A hoist (16) is movable arranged along a rail structure (17) at the top side (6) of the maintenance unit (11).
Abstract:
A flotation plant which is built to a modular storeyed structure. The flotation plant has a first storey (I), the first storey being the lowest storey of the plant and comprising a pump sump module (1). The pump sump module (1) is a rigid and self-supporting unit capable of being transferable and hoistable as an integral entity. The pump sump module (1) has a height (h1). The pump sump module (1) comprises a self-supporting framework (2), a sump tank (4) in the inner space (3) of the self-supporting framework (2), and a pump (5) connected in fluid communication with the sump tank (4). The flotation plant has a second storey (II), which is located at the level above the first storey (I). The second storey (II) includes a tank module (6) which has a height (h2). The tank module is configured to implement flotation, produce an overflow and to discharge the overflow to the sump tank (4). The height (h1) of the pump sump module (1) is 35 – 70 % of the total height (h1 + h2) of the pump sump module (1) and the tank module (2).
Abstract:
A flotation plant comprises a tank module (1). The tank module includes a self-supporting framework (2) having an inner space (3). The tank module includes at least one flotation tank (4). The flotation tank is disposed in the inner space (3) of the self-supporting framework (2).

Abstract:
A flotation unit comprising at least one flotation tank (3) and other equipment configured for implementing a flotation process for a feedstock subject of flotation. The flotation unit is built with self-supporting modules (2, 7, 11, 12, 17) to form a modular storeyed structure having superimposed storeys (I, II, III), the self-supporting modules (2, 7, 11, 12, 7) being transferable and hoistable as integral units and stackable on top of each other to form the storeys. A flotation plant may contain one or several flotation units in succession. A flotation plant may contain several groups of successive flotation units in parallel.
