Phosphoric Acid 85% Supplier — Vadodara, Gujarat

Phosphoric acid (H₃PO₄, 85% food/industrial grade) from Drashti Chemicals supports metal treatment, sugar decolourisation, fertilizer intermediates, and boiler compound formulation in Gujarat. Unlike strong mineral acids, phosphoric adds buffer capacity and nutrient value — relevant when treated water enters irrigation or when phosphate coating is the process objective.

Industrial 85% grade covers most applications; lower-grade 75% available for cost-sensitive fertilizer blending. Food-grade with heavy-metal limits required for sugar, beverage, and edible oil refining — specify on PO. Phosphoric is viscous at 85% — heated storage (40 °C jacket) or dilution to 50% improves pumpability in winter. COA confirms assay and chloride.

Metal pretreatment: 10–20% phosphoric acid dip for iron phosphate coating before painting. Sugar: 100–300 ppm in clarification. ETP: rarely used for pH due to phosphate discharge limits — prefer HCl or H₂SO₄ unless phosphate precipitation is intentional. Neutralisation with lime produces calcium phosphate sludge — account for sludge volume in clarifier sizing.

Packaging: 35 kg carboys, 250 kg HDPE drums, IBC totes. MOQ one carboy; bulk quote on request for fertilizer and metal-finishing clusters in Rajkot and Jamnagar. MSDS and COA per lot. Store above 15 °C to prevent crystallisation. GST 24AGLPC6288M1ZX. Drashti Vadodara dispatch.

Phosphoric vs. citric acid for cleaning: citric chelates scale and rinses cleaner for food CIP; phosphoric leaves phosphate film useful for corrosion inhibition on steel. Phosphoric vs. sulphuric: phosphoric is weaker, less corrosive to skin, adds nutrient; sulphuric is stronger for rapid pH drop. Choose phosphoric when downstream phosphate is asset, not pollutant.
