摘要:
The apparatus comprises a motor (16) which is mounted on a float and in which the motor drives an impeller device (20) which extends below the liquid surface (11), with the motor (16) being mounted in a chamber (12) which is fully sealed from the liquid and which serves as a float (10). The apparatus may be fitted with a supply conduit (30) in order to bring gas, such as air, from above the liquid surface to the vicinity of the impeller device (20). The apparatus may be used for the treatment, mixing and/or aeration of liquids such as for example waste water.
摘要:
System for treating an aqueous medium volume, in which a fluid sucking means (7) is associated to a fluid conveying means (4), characterized in that the sucking means is associated to the conveying means and is adapted for creating a downwards suction of fluid in the conveying means from the inlet (5) towards the sucking means, whereby the difference between the level of the inlet and the level of the sucking means is at least 40cm.

The invention describes a device for treating liquids, in particular waste water, it being possible for the device both to aerate and mix the water. This device comprises an aerator and comprises a structure to which an independently working mixer is attached. The assembly may be attached to a float or be suspended above the liquid. Preferably, the mixer will be displaceably attached to the structure. The structure may be attached to the aerator or to the float.

The decanting device mainly consists of a float (1) and a decanting container (2, 20) with an open upper side, which is provided with an overflow rim (22), and at its lower part with a drain (3). According to the invention, the float (1) surrounds completely the overflow rim (22) of the decanting container (2, 20) and the decanting container (2, 20) has guiding means allowing the decanting container (2, 20) to move vertically with respect to the float (1) between a first position in which the decanting container (2, 20) is in an "hydraulically closed "position with the overflow rim (22) fully above water, and a second position in which the decanting container (2, 20) is in a "hydraulically open" position with the overflow rim (22) located under the water level whereby the water can flow over the overflow rim (22) into the decanting container (2, 20). The decanting container is equipped on its outer surface with a closing element (5) allowing to close the passage between the decanting container and the float when the decanting container is in the closed position.

The invention describes a screw for a water treatment apparatus, such as an aerator or mixer, said apparatus comprising a power source (1) driving a shaft (2) on which is fitted a screw that sucks the water up or impels it downward. The screw consists of a helicoidal, spiral-shaped screw blade construction round said shaft, with an upper end part (A), a lower end part (C) and a middle part (B) between said two end parts, with at least one of said end parts comprising an extra screw blade.
