摘要： The control apparatus (9) makes it possible to obtain a desired quantity of a fluid produced bythe system by controlling a 'single' valve (3) provided in a secondary line which transports a concentrated liquid discharged from a reverse osmosis device (4). In one embodiment of the invention, the control apparatus is applied to a fresh-water distillation system. Once a desired fresh-water flow rate (Q 1 ) has been set, the control apparatus (9) can automatically determine a necessary valve opening (Av) in accordance with performance characteristics (21 to 28) of components [a system line between a centrifugal pump (1) and the reverse osmosis device (4)] of the fresh-water distillation system. In response to this, the valve generates a desired pressure at the inlet of the reverse osmosis device (4). As a result, the reverse osmosis device (4) produces fresh water at a flow rate which is, in practice, equal to the set value (Q 1 ). According to another aspect of the invention, means (36,38) which minimize the power of the centrifugal pump are provided. According to a third aspect of the invention, monitors (see Figures 8,10,12 and 13) which evaluate the performance of each of the components of the system are also provided. The monitors can be utilized to renew data on the performance of the system which is employed in the control apparatus.

摘要： PCT No. PCT/JP84/00180 Sec. 371 Date Oct. 5, 1984 Sec. 102(e) Date Oct. 5, 1984 PCT Filed Apr. 10, 1984 PCT Pub. No. WO84/04049 PCT Pub. Date Oct. 25, 1984.A novel control for use with a reverse osmotic treatment system is disclosed. The unit (9) provides the desired flow of product solution from the system by controlling a "single" valve (3) disposed on a secondary line for conveying a concentrated solution coming out of a reverse osmotic apparatus (4). One application of this control unit is in desalination of salt water. Once the desired level of the flow of desalinated water (Q1) is initially set, the control unit (9) determines automatically the necessary opening (Av) of the valve in accordance with the performance characteristics (21 to 28) of the components of the desalination system [centrifugal pump (1), reverse osmotic apparatus (4) and the system line]. In response to this determination, the valve develops the desired pressure at the inlet of the reverse osmotic apparatus (4), which then produces desalinated water at a flow rate substantially equal to the initially set value (Q1). In another aspect, the invention provides means (36, 38) for minimizing the power requirement of the centrifugal pump. In a further aspect, the invention provides monitors (FIGS. 8, 10, 12 and 13) for evaluating the performance of respective components of the treatment system. The monitors can be used for updating a set of information about the performance of the system with which the control unit is used.
