What is filtration in water treatment?
Using filtration in water treatment, solid particles are entirely removed from the water. This can be from ground water, surface water or even pre-treated wastewater. These processes in water treatment have a clear objective: to provide the correct quality of water for the specific industrial application.

Distillation is a process in which impure water is boiled and the steam is collected and condensed in a separate container, leaving many of the solid contaminants behind. Disinfection. Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed.
What are the steps of water treatment?
Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include: Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water.
What is a water softener?
Water Softeners. A water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.”. Distillation Systems.
Why is chlorine added to water?
After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.
How are ions removed from a solution?
First, positively charged ions are removed by a cation exchange resin in exchange for a chemically equivalent amount of hydrogen ions. Second, negatively charged ions are removed by an anion exchange resin for a chemically equivalent amount of hydroxide ions. The hydrogen and hydroxide ions introduced in this process unite to form water molecules. The term is often used interchangeably with demineralization. The cation resin is regenerated with an acid and the anion resin is regenerated with sodium hydroxide (caustic soda).
What is the plant life that is found in stagnant water?
Algae. Plant life (green scum) containing chlorophyll is usually found in stagnant surface water. Excessive growths may create taste and odor problems, and consume dissolved oxygen during decay. Sometimes it may be controlled in a pond by the addition of Potassium Permanganate.

When did hydrotherapy start?
Hydrotherapy as a formal medical tool dates from about 1829 when Vincenz Priessnitz (1799–1851), a farmer of Gräfenberg in Silesia, then part of the Austrian Empire, began his public career in the paternal homestead, extended so as to accommodate the increasing numbers attracted by the fame of his cures.
When was water used as a torture?
a. ^ While the second sense, of water as a form of torture is documented back to at least the 15th century, the first use of the term water cure as a torture is indirectly dated to around 1898, by U.S. soldiers in the Spanish–American War, after the term had been introduced to America in the mid-19th century in the therapeutic sense, which was in widespread use. Indeed, while the torture sense of water cure was by 1900–1902 established in the American army, with a conscious sense of irony, this sense was not in widespread use. Webster's 1913 dictionary cited only the therapeutic sense, water cure being synonymous with hydropathy, the term by which hydrotherapy was known in the 19th century and early 20th century.
When did hydrotherapy become popular?
Hydrotherapy became more prominent following the growth and development of modern medical practices in the 18th and 19th century. As traditional medical practice became increasingly professional in terms of how doctors operated, it was felt that medical treatment became increasingly less personalized, the development of hydrotherapy was believed to be a more personal form of medical treatment that did not necessarily present to patients the alienating scientific language that modern developments of medical treatment entailed.
What is the process of removing carbon dioxide from water?
AERATION: A process in which air is intimately mixed with water to remove undesirable gases, such as carbon dioxide and hydrogen sulfide. Carbon dioxide can be more economically removed from water by aeration than by chemical precipitation or by the use of ion exchange resins.
What is a buffer in water?
BUFFER: A substance or combination of substances that resist a change in pH when an acid or an alkali is added to water in which they are dissolved.

- Calcite
1. Calcium carbonate (CaCO3). A trade name for finely ground limestone, very high in calcium carbonate, which is used to raise the pH of acidic water. - Calcium ( Ca )
1. One of the primary elements of the earth's crust commonly found in water as a dissolved solid. The presence of calcium in water is a factor contributing to the formation of scale and insoluble soap curds which are means of clearly identifying hard water. It is sometimes referred to as lime.

- Dealkalization
1. A process for the reduction of alkalinity in a water supply. It is generally accomplished by a chemical feed processor combined cation and anion exchange systems. - Deashing
1. The removal from solution of inorganic salts by means of adsorption by ion exchange resins of both the cations and the anions that comprise the salts.
