The Water Conditioning Plant is very flexible and can be used for the treatment of water containing different kinds of pollutant substances. The quantity of pollutant substances can vary within the values that are normally shown in the industrial wastewaters. The instruments for pH and rH measurements, mounted on the unit, are fitted with analog output for the A/D conversion. The Water Conditioning Plant has been designed to perform practical experiments of water conditioning. The industrial wastewaters can be splitted in a first classification, into the ones containing organic products, determining a decrease of oxygen dissolved in the rivers where they flow and into wastes containing inorganic products whose toxicity is typical of the dissolved compounds. The realization of this equipment allows the treatment up to 170 liters of polluted water.

The Watertight Propeller Dynamometer of high capacity is sealed against pressure of up to 1 bar above atmospheric pressure and against relatively high vacuum (1 bar = 10 to the power 5 N/m2 = 0.1 MPa). Idle friction of the measuring shaft is small despite the use of sealing rings and is approximately 0.3 Nm for dynamometer and 0.4 Nm for dynamometer. The dynamometer can be used also for propulsion tests with relatively high torque and thrust values in ship models under water. That has slightly larger dimensions, but is of similar appearance. It is thus suitable for use in the measuring section of cavitation tunnels, as an inner drive dynamometer in ship models or in dummy bodies mounted in the measuring section of a cavitation tunnel.
