Caustic Soda Tanks – What is Caustic Soda?  Also known as Sodium hydroxide and lye is a highly caustic compound and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. 

Here are some main industries that Sodium hydroxide is used in:

Chemical Pumping. Sodium hydroxide is also widely used in pulping of wood for making paper or regenerated fibres. Along with sodium sulphide, sodium hydroxide is a key component of the white liquor solution used to separate lignin from cellulose fibres in the sulphate process. It also plays a key role in several later stages of the process of bleaching the brown pulp resulting from the pulping process.

Water Treatment. Sodium hydroxide is sometimes used during water purification to raise the pH of water supplies. Increased pH makes the water less corrosive to plumbing and reduces the amount of lead, copper and other toxic metals that can dissolve into drinking water.

Cement, Mortars, Concretes and Grouts. Sodium hydroxide is used in some cement mix plasticisers. This helps homogenise cement mixes, preventing segregation of sands and cement, decreases the amount of water required in a mix and increases the workability of the cement product, be it mortar, render or concrete.

Cleaning Agents. Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called “caustic”. It is added to water, heated, and then used to clean process equipment, storage tanks, etc. It can dissolve grease, oils, fats and protein-based deposits. It is also used for cleaning waste discharge pipes under sinks and drains in domestic properties.

Food preparation. Food uses of sodium hydroxide include washing or chemical peeling of fruits and vegetables, chocolate and cocoa processing, caramel colouring production, poultry scalding, soft drink processing.

Sodium Hydroxide Storage Tanks

Enduramaxx manufactures a complete range of bunded storage tanks for the processing and storage of bulk Sodium Hydroxide. Our bunded tanks have been designed explicitly with pollution control in mind. Selected for integral protection from leakage and overfilling. These plastic tanks are constructed using rotationally moulded mid-density polyethene.  These bunded Caustic Soda Tanks contain a minimum 110% volume of the inner tank. A bunded tank is a ‘tank within a tank’ which helps customers conform to current health and safety legislation.

Closed Top Bunded Tanks are available in a wide range of sizes from 400 litres to 30,000 litres.  The customisation to a client’s specific requirements is available upon request.

Open Top Bunded Tanks like our closed top bunded tanks, our open-top bunded tanks are also available in a wide range of sizes from 400 litres to 30,000 litres.  The customisation to a client’s specific requirements is available upon request.

Uses for caustic soda liquor is used in a wide variety of industries. Its primary use is to raise the pH in the water treatment process. It can also be used in a variety of other applications including;

  • Aerospace – pH balance, plating and anodising
  • Agricultural – Effluent treatment and pH balance
  • Automotive – Tanker cleaning, effluent treatment, degreaser
  • Chemical / Petrochemical – Effluent treatment
  • Cleaning – Powerful cleaner, breaks up dirt and pH adjuster
  • Electronics – Effluent treatment, pH balance, plating baths as a cleaner
  • Food & Beverage – pH treatment, cleaning of pipes, peeling of fruit & vegetables
  • Pharmaceuticals – Production of pharmaceutical intermediates and water treatment
  • Rubber Industry – Effluent treatment and reclaiming rubber
  • Waste Recycling – Effluent treatment Water Treatment
