Caustic Soda in water treatment

Caustic soda and other alkaline salts are used to regulate the acidity of water and also in the water treatment industry. The acidity can have devastating effects on water transmission systems and adverse effects on the health of consumers. Acidic water can dissolve metals from the piping system, causing corrosion and perforation of pipes, fittings, pumps, and other water transfer equipment. Metals dissolved in water may also cause health problems. sodium hydroxide is a very good option to solve this problem. Hydroxide deposition is the simplest and most common method of removing metals from water. Sodium hydroxide increases the pH of water, with this increase, the solubility of metals decreases and they gain weight and settle. one of the benefits of caustic soda is its liquid form, it does not need to be made into a slurry or solution, and the desired pH depends on the type of contaminant and its solubility limit. Sodium hydroxide has many advantages for use as an acidity regulator and purifier, this chemical dissolves well in water, it is not expensive, and it can react with less acid to precipitate in the form of salt. This mineral has become a very useful material in the water treatment industry, the high solubility of caustic soda makes it easy to use and therefore is preferred over cheaper materials such as calcium hydroxide (lime).

For acidic water, one of the ways to regulate acidity is to use liquid soda in the treatment process. Burning soda is added to the well to increase the acidity of the water. A feeder pump should be added to the water well to have a positive effect on the system and to prevent corrosion of good equipment and suction pump.

How is caustic soda used in water treatment?

To answer this question, we will describe the mechanism of action of sodium hydroxide as a specific agent or purifier of water

What does caustic soda do in water treatment?

by adding this salt to the water, the amount of acidity increases and its alkalinity increases, this causes the harmful substances to the intensity decreases and the water is purified. In some cases, caustic soda solution is pumped into the tanks of anionic resins, in the presence of these types of resins, sodium hydroxide can strengthen their properties.

Caustic soda in drinking water treatment:

The function of this substance in the treatment of drinking water is similar to the method described, A very important point in using caustic soda in drinking water treatment is to measure the amount of caustic soda after the treatment stage and before consuming it. The excessive increase of these substances leads to various diseases in humans and also causes serious damage to the skin.

Sodium hydroxide is also used to reduce the hardness of the water. Due to the various benefits of flaxseed to lime, it can be a good alternative for this purpose. Magnesium is done more completely.

How to remove caustic soda from water?

In order to clean and eliminate sodium hydroxide and other residual sodium in water, we can use the 1M hydrochloric acid solution, metal particles remaining in water can also be removed by this method, another method to eliminate Removal of residual sodium hydroxide is the use of ion-exchange resins that destroy caustic soda by this substance.
