1. Alkaline Coagulant For Water And Wastewater: Sodium aluminate supplies reactive alumina together with alkalinity, letting plants remove phosphorus and phosphate, magnesium, silicates and suspended solids and improve clarity, and it suits low alkalinity wastewater where acid coagulants need extra alkali; co-coagulation with other coagulants is routine in municipal and industrial plants.
2. Raw Material For Zeolites And Molecular Sieves: Used as the alumina and sodium source in hydrothermal synthesis of synthetic zeolites and molecular sieve grades, where a controlled Na2O to Al2O3 ratio and a low impurity profile help build a stable framework for detergents, adsorbents, desiccants and separation media.
3. Reactive Alumina Source For Catalyst Production: Catalyst producers use this soluble, highly reactive alumina source in catalyst manufacturing, and it also feeds white alumina trihydrate and carrier production; the material supports desiccant and adsorbent output and the alumina supply chain behind fluid catalytic cracking, hydrocracking, hydrotreating, reforming and isomerization units.
4. Surface Treatment Agent For Titanium Dioxide Pigments: Hydrous alumina deposited from sodium aluminate is one of the most widely applied inorganic treatments on titanium dioxide pigments, improving light fastness, dispersibility and outdoor durability while reducing chalking in exterior paints, and it also serves as a coating extender in pigment manufacture.
5. Wet End Additive For Paper And Board: Papermakers use large volumes of sodium aluminate where it raises wet end pH and improves sizing and filler retention, and it helps control pitch deposits so mills obtain more consistent sheets and fewer deposit related breaks on the machine.
