Potassium hydroxide in water treatment . Chemically known as KOH, it is more commonly known as potash or potash caustic. It is like caustic soda that can be added to water to raise the pH level. Potassium hydroxide is a white, odorless solid that is often packaged in bags in shells or pellets. Potassium hydroxide is an approved chemical with a concentration of 50% or less for multiprocessed reservoir systems.
When storing potassium hydroxide, having a proper storage method will help prevent leaks or other types of accidents. The entry of potassium hydroxide into the water creates a significant heat while forming a caustic solution. If not done properly, it can cause a violent and exaggerated reaction. It is also a severe irritant that can cause serious damage to the upper respiratory tract. If swallowed, it is toxic and corrosive to the skin.
Applications of potassium hydroxide is produced by electrolysis of potassium chloride brine in electrolytic cells. When potassium chloride brine is fed to the electrolytic cell, this process results in a solution of potassium hydroxide and chlorine and hydrogen products. Potassium hydroxide is used in a wide range of industrial applications. One of the most common applications is in adjusting the pH level of water. Used in water treatment plants. Adding potassium hydroxide makes the water much more acidic. It is a pH regulator. It works as a corrosion inhibitor in water pipes. It protects corrosion in the distribution system and plumbing system of houses.
Raw water from each source is first allocated through the tower’s packaged aeration systems. The aeration process eliminates volatile compounds, raises the pH of the water, and provides initial oxidation. The water is aerated and then enters the quick mix tanks where potassium ganate is constantly injected for final oxidation and potassium hydroxide is added to adjust the excess pH. If needed in the future, the tanks will also be equipped with a coagulation injection system (polyaluminum chloride) for color control, organic. The purified water flows as a fungus through parallel flocculation tanks to form a clot and then equates to a purification tank. From there, the pre-treated water is pumped to stored feed tanks located on each membrane slider.
Water is filtered through special infiltration pumps through microfiltration membranes. After treatment, the water is treated with sodium hypochlorite for disinfection and sodium fluoride for disinfection before entering a porous inverter for the contact time before entering the distribution system. In general, the washing water from the process is sent to recycling tanks. From there, the supernatant is pumped to the rapid mixing tanks for additional treatment, and the collected solids are sent into the on-site wetlands or wastewater.
It is a way to recover or use potassium from wastewater for multiple applications. Because algae and plants are able to survive and thrive in high-salt environments, potassium-containing wastes can be used as fertilizer for the growth of microbes, algae, and plants. Microbes, plants and algae are able to absorb essential nutrients such as nitrogen and potassium from the effluent. After reducing the potassium content of the effluent, the wastewater can be treated to separate other pollutants. On the other hand, the amount of potassium may first be separated from the wastewater to be used for the growth of microbes, plants and algae, and then used again to regenerate cationic resins in certain forms of potassium.
This article demonstrates the use of potassium hydroxide in water treatment. Potassium hydroxide is used in water treatment to regulate the pH of water. This material is used to prevent corrosion of water pipes.
