When quicklime is combined or slaked with water, it produces Lime Powder, which is a colourless crystal or white powder. It is used for a variety of purposes, including food preparation. As a flocculant in water and sewage treatment is one of its most common uses. It creates a fluffy charged solid that helps remove tiny particles from water, culminating in a cleaner product. The low cost and low toxicity of lime powder make it ideal for this purpose.
