Pulp and Synthetic Fibers: Purifying caustic soda from hemicellulose and other organic contaminants, achieving a 95% reuse rate of sodium hydroxide.

Food, Beverage, and Dairy: Purifying waste alkaline cleaning streams (CIP) and solutions regenerated after ion exchange (in sugar decolorization production), achieving a 95% reuse rate of sodium hydroxide.

Chemical Industry: Applied in alkali recovery and final product concentration in many alkaline environment production operations.

Tested alkaline solutions include:

4% NaOH Sodium Hydroxide

10% NaOH Sodium Hydroxide

20% NaOH Sodium Hydroxide

20% KOH Potassium Hydroxide

Typical applications in the above media include:

Recovery of alkaline streams (sodium hydroxide, potassium hydroxide)

Recovery of metals from alkaline streams

Recovery of spent electrolytes

Reducing COD content before neutralizing industrial wastewater

Recovery of alkaline solutions used for container and equipment cleaning

Some common applications requiring the use of strong corrosive alkaline cleaning
