Abstract: An apparatus for processing liquids such as water or the like by means of a reverse osmosis device has a main pump which provides an entrance pressure to the reverse osmosis device in connection with a throttle. In order to avoid any losses of energy, another pump is connected to the main pump. Via a rigid shaft, a turbine is connected to the other pump which turbine receives the high pressure located in the concentrate and releases it to the other pump.

Abstract: Apparatus for washing soiled comminuted products, such as comminuted plastic foils, bands or the like comprises an elongated container adapted to be filled up to a predetermined level with a washing solution into which the products to be washed are fed at one end of the container and discharged from the other end, in which a separating wall extending transverse through the container between the ends thereof defines in the container a washing zone between the one end of the container and the separating wall and a discharge zone between the separating wall and the other end of the container, and in which an agitating device is provided in the washing zone for agitating the products therein and for driving the products below a lower edge of the separating wall from the washing zone to the discharge zone, from where the cleaned products are discharged by a discharging device including a sieve drum rotatable about an axis extending transverse to the longitudinal direction of the container.
