Calcium Hydroxide: Transforming Sewage Treatment with Stupendous Significance
As a strong alkaline substance, calcium hydroxide plays an irreplaceable and important role in the field of sewage treatment. In the industrial production process, metal refining, chemical production and other links will produce a large amount of wastewater containing strong acidic substances such as sulfuric acid and hydrochloric acid.
Calcium hydroxide can react with these acidic substances to neutralize, for example, react with sulfuric acid to generate calcium sulfate and water, thereby effectively adjusting the pH value of the wastewater to a neutral or alkaline range, creating suitable conditions for subsequent treatment processes.
Applicability and limitations of calcium hydroxide in wastewater treatment
In practical applications, calcium hydroxide is particularly suitable for treating acidic wastewater with low pH values and containing heavy metal ions, and the treatment effect is stable and reliable. However, this process also has certain limitations: for high-concentration heavy metal wastewater or complex wastewater containing a large amount of suspended solids and oily substances, it may be difficult to achieve the ideal treatment effect using calcium hydroxide alone, and other treatment technologies need to be coordinated. In addition, due to the low solubility of calcium hydroxide in water, scaling problems caused by excessive local concentrations are prone to occur during operation, which may cause secondary pollution risks.
The birth and formation of CRQ calcium hydroxide production line
In order to meet the market demand for high-quality calcium hydroxide products, the CRQ calcium hydroxide production line came into being. The production line integrates the technical research and development results of Kronos for many years. It consists of core equipment such as CRSH series lime digesters, delayed digestion bins, CRHG series special grinding mills and CRXF series powder selectors, supporting 5-30t/h production capacity output.
Advantages and applications of CRQ calcium hydroxide production line


The production line adopts a modular design, which can flexibly adjust the process plan according to the characteristics of raw materials, product uses and investment budgets, and has outstanding advantages such as energy saving, environmental protection and intelligent control. Its products are widely used in more than ten fields such as metallurgy, construction, and environmental protection. Especially in sewage treatment, it can provide calcium hydroxide products with stable performance and provide reliable guarantees for key process links such as neutralization of acidic wastewater and removal of heavy metals.
The important role of calcium hydroxide in sewage treatment has been widely recognized, and the launch of the CRQ calcium hydroxide production line provides the industry with efficient and stable production solutions. In actual engineering applications, it is necessary to comprehensively consider factors such as wastewater characteristics, treatment goals and economic benefits, and scientifically select calcium hydroxide products and supporting equipment to achieve the best sewage treatment effect and promote the sustainable development of environmental protection.
