producer of alum for over half a century- is particularly well geared to supply all your alum requirements. Stringent quality controls are exercised from start to finish. Manufacturing plants are strategically located throughout the country to assure prompt, efficient service. Advantages of liquid alum. More and more firms are becoming interested in liquid alum which Cyanamid pioneered. Material costs are lower-so are costs of unloading, storing and handling. Liquid alum requires simpler, easier-to-maintain feeding equipment -less storage space. And it disperses more rapidly in water providing more effective coagulation. But liquid or dry, you can depend on Cyanamid for all your alum needs. Two grades: commercial and iron-free, in dry and liquid f o r m - both conforming fully to AWWA standards. Dry: in powdered, ground, rice-size and lump form; shipped in 100 lb. multiwalls (bulk carloads on arrangement). Liquid shipped in tank cars or tank wagons.
