Key Industrial Applications of Caustic Soda Lye 50%

✔ Water & Wastewater Treatment

Sodium Hydroxide 50% is a powerful pH neutralizer and acid scavenger used in both municipal and industrial wastewater plants. It precipitates heavy metals, neutralizes acids, and helps control biological activity.

✔ Pulp & Paper Industry

Used in pulp digestion, bleaching, and fiber separation, Caustic Soda Lye is essential in both mechanical and chemical pulping operations.

✔ Petroleum & Natural Gas

Acts as a neutralizing agent and catalyst in petroleum refining, sulfur compound removal, and fuel additive processing.

✔ Chemical Manufacturing

Serves as a base for producing sodium salts, surfactants, dyes, pharmaceuticals, and a wide range of organic and inorganic compounds.

✔ Food & Beverage (on request: food-grade only)

Used in cleaning and sterilizing processing equipment, and in certain food-safe applications such as peeling fruits and vegetables — food-grade NaOH must be specified.
