A current European water-treatment standard describes 25% w/w as a usual commercial ammonia-solution concentration and gives a density of approximately 0.906 g/cm³ at 20°C and a typical commercial-product pH of 12–13.
Applications
Mining and mineral processing, pH adjustment, neutralisation, industrial water treatment, wastewater treatment, chemical manufacturing, cleaning formulations, textile processing and industrial process chemistry.
Key Benefits
Strong alkaline performance, completely miscible with water, effective pH adjustment and broad industrial versatility.
Packaging
Supplied in compatible chemical-resistant containers. Drum, IBC and bulk supply configurations may be available depending on quantity.
Storage
Store in tightly closed compatible containers in a cool and very well-ventilated chemical storage area. Protect from heat and incompatible chemicals. Ammonia vapour is irritating and corrosive, and suitable PPE and ventilation are essential.
