Zero liquid discharge

1.Concentration and reduction of saline wastewater

2.Preparation of inorganic salts for acid-base reuse

Concentration Types: 

*Inorganic salts, such as sodium chloride, ammonium chloride, ammonium sulfate, ammonium nitrate, etc.

*Inorganic acids and bases, such as hydrochloric acid, sulfuric acid, sodium hydroxide, potassium hydroxide, etc.

*Organic acids, bases, and salts, such as formic acid, acetic acid, ammonia water, acrylic acid, sodium formate, etc.

Concentration Levels: Sodium chloride: 15-20%；Ammonium chloride: 15-20%；

Sodium hydroxide: 8-10%

Energy Consumption for Concentration:

To concentrate 1 ton of 1% sodium chloride to 15%, it consumes 3 kWh of electricity.

Application Fields
