Metabolic Pathways. 1  Although we can recognize a substrate and product. of individual enzymatic reactions metabolic. 2  Pathways can be linear, branched, cyclic or even. spiral. 3  Pathway activity is controlled in three ways.  Metabolites and enzymes may be localized in. different parts of the cell called metabolic.
Products often purchased by wastewater treatment plants include: 1  Alum or aluminum sulfate. 2  Sodium aluminate. 3  Polyaluminum Chloride.  Polymer 1  (dewatering) Sodium hydroxide.  Ferric 1  Chloride. Ferrous Chloride.
To take care of pathogens in the water, you have to introduce a disinfecting agent that will get rid of them. The most popular pool disinfectant is the element chlorine, in the form of a chemical compound such as calcium hypochlorite (a solid) or sodium hypochlorite (a liquid). When the compound is added to the water, the chlorine reacts with the water to form various chemicals, most notably hypochlorous acid. Hypochlorous acid kills bacteria and other pathogens by attacking the lipids in the cell walls and destroying the enzymes and structures inside the cell through an oxidation reaction.
