Soda Ash Light (Sodium Carbonate) Supplier — Vadodara

Soda ash light (Na₂CO₃) is used for pH correction, glass batching, detergent formulation, and water softening at plants across Gujarat. Drashti Chemicals Vadodara supplies light soda ash so procurement can issue one PO. Light grade dissolves faster than dense — useful in continuous neutralisation loops where undissolved granules can blind screen filters.

Match the lot on bulk density, chloride and iron, not on a producer name. Typical light-grade bulk density is about 0.55 g/cm³. Specify chloride and iron limits on the PO for food-adjacent or glass use — we quote lots against those ceilings.

Dosing for pH adjustment: soda ash light reacts roughly twice as fast as hydrated lime in cold water, making it preferred in winter at outdoor neutralisation pits. Rule-of-thumb: 1 kg soda ash raises 10 m³ of pH 4 water to approximately pH 7 — verify with your alkalinity titration. Overdosing pushes pH past 10 and precipitates calcium as carbonate scale on heat exchangers. Start at 80% of calculated dose and titrate.

Packaging: 50 kg HDPE-lined bags standard; jumbo bags and bulk pneumatic tanker for plants above 20 MT/month. MOQ one bag for lab validation; pallet quantities dispatch same day from Vadodara. COA and MSDS included. GST 24AGLPC6288M1ZX. Store dry — soda ash is hygroscopic and caking in monsoon storage is the main quality complaint we help clients solve with sealed bins and first-in-first-out rotation.

Soda ash light vs. caustic soda: soda ash adds carbonate alkalinity and is safer to handle; caustic gives sharper pH lift per kg but exotherms on dissolution and demands SS316 dosing systems. Soda ash vs. lime: soda ash avoids sludge from lime dissolution and works in closed-loop systems; lime wins on raw cost for large open ponds. For boiler feed softening, pair soda ash with ion exchange rather than relying on chemical softening alone.
