J sfllllll— i The W & T ??EQUISCALE” VISIBLE VALLUM CHLORINATOR T yp e M S V E -M Chlorination, by its very nature, is a precision operation. Applying chlorine for water purification, sewage treatment or any other process, a chlorinator must accurately measure and thoroughly diffuse millionths of a pound of chlorine to each gallon of water, sewage or unit of volume being treated. Variable conditions of chlorine temperature and pressure are only the beginning of a long chain o / variable factors each of which must be controlled by the chlorinator in performing its important work. Preventing overdosage and underdosage of chlorine is obviously important. Equally important . . . a chlorinator must com­pensate for the many variable factors and must maintain a dependable accuracy during a long life, with a minimum of maintenance. To meet these requirements, a chlorinator must be designed on sound engineering principles . . . must be built in accordance with the highest standards of precision manu­facture . . . of the finest materials available. Recognized as the leader in the field of chlorination, the W &T Visible Vacuum Chlorinator meets all of these demands . . . Years of operation in all kinds of service have proven the Visible Vacuum principle to have many advantages over any other principle of chlorinator design. All of the working parts of the apparatus are housed under a glass bell jar . . . visible to the operator at a glance. Hydraulic operation eliminates the need of small delicate parts . . . there are no springs or diaphragms to require continual attention. Chlorine gas . . . always under a partial vacuum from the time it enters the equipment, cannot readily escape. Since water controls the operation, the chlorine supply is automatically shut off when the water supply is shut off for any reason. For cleaning or adjustment of the equipment chlorine may be removed from the interior by closing the chlorine inlet valve manually
