Discover how quicklime for water treatment in India plays a vital role in improving water quality by controlling pH levels, removing impurities like heavy metals and suspended solids, and supporting effective wastewater treatment processes. In India, where industrial and municipal water pollution is a growing concern, quicklime (calcium oxide) is widely used to neutralize acidic water, precipitate phosphates, and enhance flocculation in treatment plants. For example, in the Ganga River cleanup projects, quicklime has been applied to reduce chemical oxygen demand (COD) by up to 40%, as reported in a 2023 study by the Central Pollution Control Board. To maximize effectiveness, operators should dose quicklime at 100-200 mg per liter of water, depending on initial pH and contaminant levels. This approach not only meets Indian discharge standards (IS 1050 but also reduces sludge volume by 15-20% compared to alternative chemicals like lime slurry. For best results, combine quicklime with coagulants such as alum to improve settling rates. By adopting these practices, water treatment facilities across India can achieve cost savings of up to 30% while ensuring compliance with environmental regulations.
