The dissolveris a pressure resisting, double cham-bered container, fitted with inlet aijdoutlet pipe connections, operatingcocks and rate of flow valve. A known weight of filter alum be-ing placed in the inner compartment,the inlet and outlet valves are openedpermitting a definite number of gal-lons of water to flow through the dis-solver under pressure in a length oftime that will insure every particle ofalum being dissolved. About 100 min-utes is usually allowed to wash everytrace of alum from the dissolver. The filtered solution of varyingstrength is piped, under pressure, tothe mixing tank, where the flow intothe tank is through a nozzle, thestream being directed against thefloor of the tank. This nozzle createsa violent churning action in the tankwhich effectively mixes the contentsof the tank. The solution is emptied, by meansof a v
