Importance of Caustic Soda in Water Treatment

March 01, 2021

Caustic soda, also known as lye, is an alkaline chemical compound and a chlorine by-product. It is used in a wide range of sectors, including laundry, textiles, and food and beverage. However, today we will concentrate on the importance of caustic soda in water treatment. Caustic soda is named for its caustic or corrosive qualities, which can cause significant chemical burns if not properly treated. If you want to import caustic soda, you should know what type of caustic soda you need and how to store it. The way good caustic soda is made by getting in touch with caustic soda flakes suppliers in Dubai.

At room temperature, sodium hydroxide is a substantial white present as caustic soda flakes, granules, or pellets. It is in a liquid shape, colorless, and denser than water. It often becomes slippery and tries to reach weak points in storage tanks, leading to leaks.As it is liquefied in water or neutralized with acid, it delivers reasonable quantities of heat, which may use the light up the fuel materials. This is a safe and cost-effective alternative to sodium hydroxide (caustic soda) for alkalinity and pH correction of wastewater. Below, therefore, are significant benefits of using caustic soda for water. 

Water Purification

Due to its high alkaline qualities, caustic soda is also used as a purifying agent for water, serving as a disinfectant and eliminating impurities while also increasing its pH. It is commonly found in industrial or private water treatment systems.

Control the PH and Reduces Harm

Controlling the pH of industrial wastewater is necessary to prevent damage to wastewater collection/transmission infrastructure by minimizing the corrosive effect of gaseous acidic pollutants such as H2S or, if extended to farmland, by preventing damage to irrigated crops. If the wastewater reaches the treatment facility, pH regulation is essential for optimizing aerobic and anaerobic microorganism behavior. Therefore, caustic soda price plays the main factor in various wastewater treatment applications.

Reduces Corrosion

One possible way to minimize water's corrosiveness, while reducing excess calcium carbonate deposition is to transfer post-treatment chemicals from lime to caustic soda to change the pH. Caustic soda or Sodium hydroxide (NaOH) raises the water's pH without calcium ions required for calcium carbonate precipitation. As a result, caustic soda should reduce the risk for calcium carbonate precipitation relative to lime for a given pH adjustment.

One way to reduce the deterioration of pipes is to create water that is not corrosive to metals such as cast iron, lead, and copper. Non-corrosive water prolongs the pipes' life and reduces the amounts of information and copper in the water. One way to minimize water corrosively is to increase the pH. This improvement can be conveniently accomplished in a treatment plant where chemicals and feed systems are already required for pH modification.

The use of caustic soda in Dubai instead of lime can minimize calcium carbon precipitation while achieving the required final water pH. However, the advantage of caustic soda over lime can only be understood under specific water safety standards. Generally, caustic soda offers soft water some advantage over lime. The value of caustic over lime reduces as the hardness of calcium increases.

The processing of caustic soda or lee is hazardous and could result in severe chemical burns on the skin. Apart from common sense and prevention, such as marking the beverage and keeping it away from children and pets, caustic soda needs more comprehensive precautions because it can cause significant burns. Always get in touch with caustic soda suppliers in Dubai to avoid such incidents.
