Zeolite-A is used as a detergent builder to remove hardness causing calcium and magnesium ions from the water. Zeolite-A is used as an alternative to polluting sodium tripolyphosphate in the powder detergents
- A world class technology for the manufacture of Zeolite–A powder is developed and commercialized.
- Prepared Zeolite-A has calcium binding capacity of 160-170 mg of CaO/g and particle size of less than 5 micron.
- The physicochemical properties of product Zeolite – A powder compete with those of produced by Degussa, PQ Corporation, SPIC Fine Chem. etc.
- In the process sodium silicate and sodium aluminate solution allowed to react in different steps under controlled conditions to prepare Zeolite-A.
- Expertise is available to produce Zeolite–A powder using bauxite, Bayer liquor, sodium aluminate powder, waste alumina, kaolin and siliceous earth as starting materials
CSMCRI have successfully commissioned and undertaken trial runs for the production of Zeolite – A on commercial plant of the capacity 10,000 MT/annum
With stringent environmental regulations and demand for green alternatives causing water pollution, the Zeolite-A as a detergent builder has excellent opportunity
The process generates alkaline effluent containing sodium hydroxide, which can be treated using appropriate technique to recycle/reuse DM or RO water.
Technology has been licensed to different industries.
Commercialized, Under commercial production by NALCO, Odisha and Gujarat Credo Minerals Industries Limited Gujarat
Silica source (sodium silicate or silica containing waste), alumina source (sodium aluminate, aluminum hydrate, or alumina waste), sodium hydroxide, RO or demineralized water etc.
Raw material storage tanks, solution preparation tanks, Jacketed Reactor with stirrer, Pumps, Filter press, spray drier, packing unit etc.
Robust technology with capability to use waste and economic raw material for the preparation of Zeolite-A, will make the process techno-economical feasible and competitive in the open market.
Process know-how for Zeolite-A; Demonstration of the process at 25 Kg/batch; License fee, royalty and other financial details are available on request.
