Inquiry (采购产品): COMMERCIAL GRADE GRANULAR ALUMINUM SULPHATE Please email me asap provided if your company can supply COMMERCIAL GRADE ALUMINUM SULPHATE (A12 (SO4)3 14 H2O)(Adapted from AWWA B 403-93)which meets the below requirement at the lowest price, thanks Quantity: 12,000 METRIC TONNES OF GRANULAR ALUMINUM SULPHATE PACKAGING Aluminum Sulphate should be packaged in 1 tonne bags and 25 kg bags and must be shrink wrapped and properly palletized. The pallets shall be sufficiently braced at both and the center so as to prevent their collapsing. Aluminum Sulphate is prepared from aluminum hydroxide,aluminum trihydrate or alumina-bearing ores such as clay and bauxite. The aluminum ore is ground to a required fineness and digested with sulphuric acid at elevated temperatures Insoluble materials are removed by sedimentation and the supernatant solution is allowed to crystallize into a solid, dry hydrate product A12(SO4)3 14 H2O containing 17% A12 O3. The purchase of Granular Aluminum Sulphate shall be based on the percent soluble aluminum, expressed as A12O3 generally 17% for the solid hydrate. BASIS FOR REJECTION AND PROVISION FOR RETESTING 1.3.1 REJECTION: The basis of rejection of solid Aluminum Sulphate offered or purchased shall be: - (a) Available water-soluble aluminum of the solid aluminum Sulphate less than 9.0% as A1 or 17.0% as A12O3. (b) Total water soluble iron expressed as Fe2O content shall be no more than 0.75 percent on the basis of 17.0% A12O3. (c) Insoluble material in excess of 0.5 percent and foreign material such as pieces of wood, “fibrous material”, and grit, which may result in the malfunctioning of dosing pumps. (d) Excessive finely powdered materials as to constitute a dust nuisance on the plant compound as a result of emptying of bags containing Granular Aluminum Sulphate. **** Hidden Message ***** Peter Beharry FL 33166 USA Company: Pharm Trin E-mail: pharmtrinp@yahoo.com **** Hidden Message ***** pharmtrinp@yahoo.com
