Product Description

Food Grade Slaked Lime Powder Calcium Hydroxide For Sewage PH Value Adjustment

Product Description

Our high-quality Lime Powder, also known as Hydrated Lime, Slaked Lime and Calcium Hydroxide, is a premium industrial-grade product manufactured with advanced production techniques in China. It is a white, odorless fine powder with excellent chemical stability and strong reactivity, widely used in mining, water treatment, flue gas desulfurization and other industrial fields.

This Lime Powder features high purity (≥90%), low impurity content and uniform particle size distribution, ensuring reliable performance in various applications. In mining operations, it is ideal for ore dressing water treatment, pH neutralization of mining wastewater and solid-liquid separation assistance, effectively reducing environmental pollution and improving production efficiency. For water treatment scenarios, it can quickly adjust the pH value of sewage, remove heavy metal ions and clarify turbid water, suitable for municipal sewage, industrial wastewater and mining drainage treatment.

In addition, our Lime Powder is widely applied in flue gas desulfurization in power plants and factories, effectively absorbing sulfur dioxide and reducing air pollution. It also serves as an ideal auxiliary material in construction, papermaking and chemical industries, with good compatibility and stable performance.
