Document Summary
The ph, hardness, total dissolved solids, metals, organics, surfactants, nutrients, oils and greases, and hydrocarbons are the chemical water quality parameters. It is a method of expressing the concentration of hydrogen ions. Monitoring and measuring ph levels is critical in all phases of environmental engineering and science. The ph of water is an important consideration because it determines its suitability for both human consumption and industrial use. Water ph has an impact on chemical coagulation, disinfection, water softening, and corrosion control. When using biological processes to treat wastewater, ph must be kept within a range that is beneficial to the organisms involved. Chemical processes used to coagulate wastewaters, dewater sludge, or oxidize certain substances, such as cyanide ion, necessitate tight ph control. The dissolution of multivalent metallic cations such as calcium, magnesium, strontium, ferrous iron, and manganese ions causes water hardness.
