While both vitamin B12 and folic acid play essential roles in supporting health, their functions in the body differ. Vitamin B12 is crucial for the formation of red blood cells, the maintenance of the nervous system, and the synthesis of DNA. Folic acid is also involved in DNA synthesis and cell division, making it vital for the growth and repair of tissues. Additionally, folic acid is especially important during pregnancy for the development of the fetal neural tube.
Coagulants, such as alum (aluminum sulfate) and ferric chloride, are also employed in sewage treatment. These chemicals assist in the removal of suspended solids, colloidal particles, and turbidity from wastewater. When added to the treatment process, coagulants promote the aggregation of small particles into larger flocs, which can be more easily removed through sedimentation. This process is particularly important in primary treatment phases, where physical separation of solids occurs.
