Distilled water and sterile water are totally different. Water in pristine form, (as in the rain water or water obtained from snow) is called pure water. When water is taken from other sources (that is other than rain water) it may contain salts and other dissolved solids and this is therefore impure water.
To remove these salts or other dissolved solid etc from the impure water the process of distillation is used. Distillation is a process in which water is boiled and heated till it evaporates and the evaporated vapour is cooled, thereby condenses to form water again. This processed water is called distilled water.
Uses of distilled water are for working, cleaning of sensitive chemical plants, machines etc, and in preparation of chemical solutions where pathogens, microorganisms are not of concern. It be noted that distilled water is pure water free from other chemicals etc but is not sterile.
Sterile water is that which inhibits the growth of microorganisms. Since in nature there are a variety of microorganisms which withstand and survive heat treatment even beyond 100{+0}C, these temperature resistant organisms resist and survive after the process of distillation.
Thus the distilled water though pure, is not sterile water. So further processing of distilled water is done to make this water sterile. This is done by autoclaving the distilled water where due to increased pressure in the autoclave (as happens in domestic pressure cooker) the temperature is raised much beyond 100{+0}C due to which the high temperature resistive microorganisms called pyrogens get destroyed, rendering the distilled water sterile.
Thus, the difference between distilled water and sterile water is that whereas distilled water is not free from microorganisms and may permit their growth, sterile water is totally free from microorganisms .No organic growth is possible in this. It is this sterile water which is used for injections and parentaral preparations in pharmacy.

Sterile water is clean water without any other chemicals added. Sterile Saline is a solution of 0.9% Sodium Chloride used for would irrigation and cleaning.
Both are used for cleaning wounds. Lets take a look at some advantages and disadvantages of both of them:
0.9% Sodium Chloride Saline is the traditional antiseptic and wound cleansing solution used today in hospitals. Whilst it has minimal healing properties, it does not have any detrimental properties either.
Water has been used for centuries as a cleaning solution for wounds. However, water causes wounds to 'weep' resulting in more frequent dressing change. This can be very inconvenient and if it is neglected it can cause infection.
Therefore I think that Saline Solution is the better choice for cleaning wounds.

What is the difference between sterile distilled water and sterile water?
Sterile distilled water has been purified through the process of distillation, which removes impurities and minerals. Sterile water, on the other hand, has been sterilized to remove any microorganisms but may still contain mineral content.
What is the difference between sterile water and buffered water?
you can get mumps off sterile water!
Are there any difference between distilled water used for batteries and distilled water used for terbine washing?
No, distilled water is distilled water.
What is the difference between bottled spring water and bottled distilled water?
*
Are sterile water and sterile distilled water the same?
no. Distilled water has had all chemicals and minerals removed, usually by steaming and re-condensation. Sterile water has been treated, usually heat treated, to destroy pathogens (any living organisms). So, you can sterilize distilled water, but not all distilled water is sterile. manufacturing criteria do NOT require that regular distilled water be packaged to prevent contamination. Water sold as sterile water must be packaged to avoid contamination. On the other hand, water full of minerals can be sterilized; the minerals are still present. So if you want mineral free, organism free water, you need sterile distilled; if just mineral free, distilled.
What is the difference between bottled water and distilled water?
The main difference between distilled and bottle water is the ions and minerals found in them. In distilled water, no ions nor minerals can be found while in bottled water such elements are present. The taste is also different due to the ions present (or absent in the case of distilled water) in the water. !!
How is water distilled?
Distillation is achieved by boiling the water and collecting and cooling the evaporate in a sterile container.
What is the difference between bottled spring water and distilled water, and which tastes best?
The water in my area sometimes tastes odd. What is considered the better choice in terms of pure drinking water? How does bottled spring water compare to distilled water? Whats the difference between the two?
Can you use sterile water in place of distilled water in a cigar humidor?
Yes. Just make sure it is a medical grade sterile water. Don't use boiled tap water. Ideally you should use propylene glycol (PG) as well.
What is the difference between sterile water and bacterial static water?
sterile water is just free from microrganisms while pyrogen free water is specifically free from those orgainsms which cause fever.
Explain the difference between tap water and distilled water?
Tap water contains impurities like nutrients, some trace elements, and microorganisms. Distilled water is close to pure H20.
What is difference in water and distilled water?
Distilled water is more pure than tap water or seawater.
