Abstract: The equipment for collection of impurities in stagnant waters having a catamaran design includes two catamaran floats (1) having a form of a hollow body terminated by the jaws (7), where at the front part of the catamaran floats (1) there is mounted in the frame (2) the conveyor belt (3) with the removable mesh belt (11) with fixed forks (12), with the drive (5) of the belt (11). At the middle part of the catamaran floats (1), under the conveyor belt (3), there is attached the removable container (8), in the cavity of the catamaran floats (1) there are the batteries (14) connected to the photovoltaic cells (9), which are installed on bracket (4) of the photovoltaic panels and at the end of the catamaran floats (1) there is fixed the marine engine (13), the rudder (6) and the remotely programmable control (10), and the equipment is also provided with a separate remote control—a joystick.

Abstract: An equipment for disposal of cyanobacteria in stagnant waters has a float structure, to which two types of bipolar electrodes (1 and 6) are mounted under the surface of water, interconnected and supplied with electric direct current via an alternator (10). The equipment comprises a supporting float (5) having the shape of a hollow body, in which there is a transversely positioned rib (4) with an attached suspended electrode (1), interconnected to supplies of photovoltaic cells (8) and alternator (10), fixed on the rib (4) there is the device (9) for utilizing wind power, connected to an alternator (10), driving the water pump (2), which is placed in the delivery pipe (3) and is connected directly to the axis of the device (9), for utilization of wind power. Fixed on the supporting float (5) there is the upper float (7) with the anchored grid electrode (6) and with the stored photovoltaic cells (8), interconnected with the electrodes (1) and (6).
