||A poisonous odorous gas widely used to kill harmful bacteria in a drinking water supply. Ingestion of chlorine can cause bladder, rectal, and breast cancer.
||An intestinal protozoan parasite resistant to chlorine. It infects the intestines and causes diarrhea, nausea, and cramps.
||A group of chlorine-resistant micro-organisms that when ingested can cause gastrointestinal illness.
||In many areas fluoride is added to water for the purpose of preventing tooth decay. This process is referred to as water fluoridation. Fluoride is
usually added after the disinfection process. In the United States, fluoridation is usually accomplished by the addition of hexafluorosilicic acid, which decomposes
water, yielding fluoride ions.
||A disease that results from an infection by the by the protozoan parasite Giardia, caused by drinking water that is either not filtered or not chlorinated.
|Is short for micrometre which is equal to one millionth of a metre. A Micron rating is the average size of the openings between pieces of filter media.
For example, a 40-micron filter has larger openings than a 5-micron filter. Consequently, the 40-micron filter element will let larger particles pass through the filter
vs the 5-micron element.
As a general rule, the smaller micron rating for a filter is better, but as with most everything, there is a trade-off. Flow capability usually drops off as the micron rating
gets smaller. To overcome this, low micron-rating filters must have larger elements to keep from sacrificing precious flow.
||A measure of the general acidity or alkalinity of a substance. A Neutral pH is 7.0 with acidic substances ranging from 0 to 6.9 and basic substances
ranging from 7.1 to 14.
||A synonym for drinkable water and is a measure of water quality
||Volatile Organic Chemicals. Synthetic chemicals dissolved in water, like insecticides and herbicides, which vaporize at low temperatures.
