In a water treatment plant, the chemical species of salt load primarily include sodium (Na+), chloride (Cl-), calcium (Ca2+), magnesium (Mg2+), sulfate (SO4²-), and bicarbonate (HCO3-). These ions can originate from natural sources, such as mineral leaching, as well as from anthropogenic activities, including industrial discharges and road salt runoff. Managing the concentration of these salts is essential to prevent issues like scaling, corrosion, and negative impacts on aquatic life. Treatment processes often involve precipitation, ion exchange, or reverse osmosis to reduce salt concentrations effectively.
The chemical energy in tap water mostly comes from the treatment process that water undergoes in water treatment plants. During treatment, chemicals are added to purify the water, and these chemicals contribute to the chemical energy in tap water. Additionally, some chemical energy may come from natural minerals dissolved in the water as it flows through rocks and soil before reaching the treatment plant.

Chemical treatment is not typically considered a step in the three primary steps of water treatment, which are generally coagulation/flocculation, sedimentation, and filtration. Chemical treatment is often incorporated into these steps to aid in the clarification and disinfection of water.
