What does 'slaking' help achieve in wastewater management?

Slaking is a process specifically related to the preparation of lime, which is crucial in wastewater management. When quicklime (calcium oxide) is added to water, it reacts with moisture to form calcium hydroxide, also known as slaked lime. This reaction results in the heat generation and transforms the quicklime into a usable form for various water treatment processes.

The use of slaked lime in wastewater management is vital for several applications, including pH adjustment, phosphorus removal, and softening of water. By preparing lime correctly through slaking, treatment facilities can ensure that the lime will effectively treat wastewater and achieve the desired water quality standards.

While other choices involve aspects of wastewater treatment, they do not directly relate to the specific process of slaking and its primary purpose in preparing lime for use in water treatment applications.
