Ever since 2000 BC, people of ancient Greek have already known that boiling water might purify it, and they are also equipped with the knowledge of using sand for filtration. Even though at that time people only judge the cleanness of water by the turbidity of it. Little is known about microorganisms or chemical contaminants. It was not until 1500 BC that people started to use alum, an ancient kind of water treatment chemical, to purify water. But, right now, after such a long history of water treatment, chemicals that could be used for purifying water are various. So, what exactly are they? Please let me introduce them to you in the following contents.
Here is the content list:
l lWhat types of chemicals can be added to treat water?
l lWhat types of water treatment chemicals are used most often?
Even though using chemicals for water treatment has a long history ever since the Egyptians first discovered the principle of condensation. The flourishment of water treatment chemicals is started from industrialization in the past two centuries. During the two hundreds of years, a great variety of water treatment chemicals have been developed and been used in the water treating industry. Basically, 15 types of water treatment chemicals are still in use nowadays. Which are algaecides, antifoams, biocides, boiler water chemicals, coagulants, corrosion inhibitors, disinfectants, defoamers, flocculants, neutralizing agents, oxidants, oxygen scavengers, pH conditioners, resin cleaners, and scale inhibitors.
Since the range of types of water treatment chemicals is so broad, and the length of this passage is limited. Today, I mainly talk about the three most often used types among all the 15 types of water treatment chemicals. The first is algaecides, which are water treatment chemicals that kill algae and cyanobacteria or green algae when added to water. Algaecides are effective against algae, but due to environmental reasons, they are not very useful in eliminating algae blooms. Defoamer is another type of water treatment chemical that is special used to eliminate foam. The cause of foam is complicated research in physical chemistry, but we already know that the existence of foam has serious problems in the operation of industrial processes and the quality of the final product is affected. If uncontrolled, foam will reduce the capacity of the equipment and increase the construction period and cost. The defoamer blend contains oil mixed with a small amount of silica. Due to these two properties of silicones, they can decompose foam. Antifoam powder covers a group of products based on modified polydimethylsiloxane. The defoamer is chemically inert and will not react with the defoaming medium. They are odorless, tasteless, non-volatile, non-toxic, and will not corrode materials. Corrosion inhibitor is another kind of water treatment chemical. Corrosion is a general term that refers to the conversion of metals into soluble compounds. Corrosion can cause the failure of key components of the boiler system, the deposition of corrosion products in key heat exchange areas, and the overall efficiency decline. This is why corrosion inhibitors are often used. Inhibitors are chemical substances that react with the metal surface and can provide a certain degree of protection for the metal surface. To put it in a more specific way, Inhibitors can form a film on the surface of the metal, therefore isolate the metal and the oxygen in the open air, so that the reaction between the metal and the oxygen could be largely decreased, and the surface of the metal part is finely protected.
