Import Aluminum Sulfate — Buy in Bulk from Supplier in Portugal

Aluminum sulfate from Vanity Bubble Chemicals Unipessoal Lda is supplied as a technical-grade coagulant primarily used in water treatment and paper manufacturing. The product is available in liquid form, filled to order in IBC containers, pallet cans, or bulk quantities depending on buyer requirements. Delivery is offered within three working days to the buyer's specified location from the supplier's warehouse in Anadia, Aveiro district. The source does not state a specific purity percentage, CAS registry number, or Al2O3 equivalent content, so buyers should request a certificate of analysis before ordering.

The material is typically manufactured by reacting bauxite or aluminum hydroxide with sulfuric acid, yielding a solution containing aluminum sulfate with varying degrees of hydration. Standard commercial grades for water treatment typically contain 8.0% to 8.5% Al2O3 by weight when expressed on a dry basis, though this supplier does not confirm this figure. Liquid aluminum sulfate solutions commonly have a specific gravity between 1.32 and 1.35 at 20 degrees Celsius for the standard 8.3% Al2O3 grade. pH of a 5% solution typically falls between 2.5 and 3.5, reflecting the acidic nature of the hydrolyzing aluminum species. Bulk density of solid hydrate forms ranges from 1,000 to 1,100 kg per cubic metre, though this supplier ships only liquid forms.

Principal applications include municipal and industrial wastewater treatment, drinking water clarification, and sizing in paper production. The coagulant neutralises negatively charged colloidal particles, enabling floc formation and sedimentation. Paper mills use it to control pH during sizing with rosin or alkyl ketene dimer. Buyers in the Iberian water sector, Portuguese paper mills, and industrial facilities requiring pH adjustment or phosphorus precipitation represent the core market. The supplier's three-day delivery commitment suits buyers with tight inventory cycles. All technical specifications, including exact concentration, free acid content, and trace metal limits, should be confirmed directly with Vanity Bubble Chemicals Unipessoal Lda before contract finalisation.
