The time will of course vary with theheight of solution at which it flows into the Montejus and the air pressureused in forcing it out. Automatic Montejus apparatus is made in stoneware for lifting solu-tions which act on lead. These are built to withstand a pressure offrom 60 to 75 lb., and have capacities ranging as high as 225 cu. ft., perhour. APPARATUS AND APPLIANCES Air Lifts.—One of the best ways of elevating corrosive solutions bvcompressed air is by the air lift system. It is especially applicable tounfiltered solutions, containing grit, that might have an injurious effecton either metal, stoneware, or rubber pumps. The apparatus is simple,cheaply installed, and entirely automatic. Fig. 107 shows the usualarrangement of the air lift for corrosive solutions. If lead is unaf-fected by the solution, the entire
