Ensuring access to clean water is a global priority, and chemical treatments are fundamental to achieving this goal. Calcium hydroxide, commonly known as slaked lime, is a vital chemical used extensively in water and wastewater treatment processes. Its efficacy, cost-effectiveness, and broad applicability make it a cornerstone of modern water purification. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality calcium hydroxide essential for municipal and industrial water treatment facilities.

One of the primary functions of calcium hydroxide in water treatment is pH adjustment. Many natural water sources are acidic due to environmental factors or industrial discharge. Adding calcium hydroxide, an alkaline substance, raises the water's pH to a neutral or slightly alkaline range. This is critical for preventing corrosion in pipes and ensuring water is safe for consumption and distribution. The process involves the reaction: Ca(OH)2 + 2H+ → Ca2+ + 2H2O.

Calcium hydroxide also plays a crucial role in water softening. It reacts with dissolved bicarbonates of calcium and magnesium, precipitating them out of the water as insoluble carbonates and hydroxides. This process, known as lime softening, reduces the hardness of water, preventing scale buildup in pipes and appliances. The reactions involved are complex, but fundamentally aim to remove dissolved minerals that cause hardness.

Furthermore, calcium hydroxide is employed as a coagulant and flocculant. When added to water, it helps to aggregate smaller suspended particles, forming larger flocs that can be more easily removed through sedimentation and filtration. This is particularly effective in removing turbidity and color from water, as well as in precipitating certain heavy metals. Its application in wastewater treatment also includes stabilizing sludge and neutralizing acidic industrial effluents.
