The three types of microbial control methods are: disinfection, sterilization, and commerical sterilization.
Sterilization is the complete removal of all microorganisms ( e.g: becteria, virsues,...etc) from the surface area of 'anything' While Disinfection is an in-complete removal of microorganisms from" inanimate or nonliving" objects. and has three distinctive levels. High level disinfection, intermediate level, and low level. Both sterilization and disinfection have chemical and physical methods. And since the question is about the methods of sterilization then there are: physical methods: Heating and radiation chemical methods: some chemicals like 'Etheline Dioxide', or by chemical evaporation.
Disinfection refers to the destruction of pathogenic microorganisms but not their spores. Common disinfectants like bleach, alcohol, and hydrogen peroxide can effectively kill bacteria, viruses, and fungi, but may not eliminate spores which are more resistant and require stronger methods like sterilization.
Chlorine, bromine, uv, ozone.
High, intermediate, and low are the three levels of disinfection. This is in the context of medical devices.

I know one way to purify water is by filtering it with some sort of aquifer-like material. Three common methods of purifying water are filtration, chlorination and ultraviolet light disinfection. There is also reverse osmosis, distilling and Ionization. The methods used depend on how dirty the incoming water is, and how pure you want the water to be. See NSF and EPA standards for specific information.
Some alternative methods to purify water besides boiling include using water filters, chemical disinfection methods like chlorine or iodine tablets, ultraviolet (UV) light treatment, and distillation.
Disinfection the process of destroying pathogenic organisms or rendering them inert. Disinfection differs from antisepsis in that its a method of disinfection using chemical solutions.
The strongest disinfection method is usually considered to be a combination of high heat (such as autoclaving) and chemical disinfectants like chlorine bleach or hydrogen peroxide. These methods are effective at killing a wide range of microorganisms, including bacteria, viruses, and fungi.
