Oxidation-reduction phenomena are highly significant in the environmental chemistry of natural water and ,wastewater,. In a lake, for example, the reduction of oxygen (O 2) by organic matter (represented by CH 2 0). [CH ,2 O, + O 2 → CO 2 + H ,2 O,], results in oxygen depletion that can kill fish.. The rate at which sewage is oxidised is crucial to the operation of a waste ,treatment, plant.

Another way to neutralize acidic water is to add a solution of, sodium hydroxide, or, sodium carbonate, (soda ash). This is usually done by installing a chemical feed pump before the pres-sure tank. If you are on a low-sodium diet, con-sider using potassium hydroxide instead of the sodium salts. This treatment system is simple, and inexpen-
