<p>PCT No. PCT/AU86/00352 Sec. 371 Date Jul. 21, 1987 Sec. 102(e) Date Jul. 21, 1987 PCT Filed Nov. 21, 1986 PCT Pub. No. WO87/03275 PCT Pub. Date Jun. 4, 1987.An electronic control and dosing system for desalinators (10) has a baffle, disposed between the evaporation and condensation chambers, fitted with probes (70, 71) which detect the presence of liquid created by entrained bubbles, that pass through the holes in the baffle. A control circuit (72), connected to the probes (70,71), closes a solenoid valve (62) to shut off the supply of feed water to the desalinator (10) until the threat of entrainment has passed. A foaming and/or scale inhibiting polymer, contained in a tank (64), is periodically introduced to the feed water inlet line (63) by a solenoid valve (65) controlled by a timer circuit (66).</p> |
