Acid-Resistant Alkali Membrane

Working Principle



The acid-resistant alkali membrane uses advanced membrane technologies such as permeation, reverse osmosis, nanofiltration, ultrafiltration, and dialysis to effectively avoid secondary pollution. This new separation technology not only purifies waste liquids but also recovers valuable substances. It is energy-efficient, low-cost, pollution-free, simple to operate, and easy to maintain, making it highly promising for treating acidic and alkaline waste liquids.



Applications



•  Chemical Industry: Recovering acids in production processes using acidic media and concentrating final products.

•  Food, Beverage, and Dairy Industry: Purifying and reusing acids from CIP processes during production and equipment cleaning.

•  Metal Recovery: Extracting metals like copper, zinc, cobalt, molybdenum, tungsten, uranium, and gold from extraction residues.

•  Industrial Wastewater: Concentrating metals in industrial wastewater to reduce operational and wastewater treatment costs.

•  High-Value Metal Recovery: Recovering valuable metals from discharge streams and industrial wastewater.

•  Carbon Slurry Process: Efficiently pre-separating copper and gold ores to improve subsequent gold extraction rates.

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

•  Food, Beverage, and Dairy: Purifying waste caustic solutions from CIP and ion exchange regeneration solutions (used in sugar decolorization), achieving a 95% reuse rate of sodium hydroxide.

•  Chemical Industry: Recovering alkali in many alkaline production operations and concentrating final products.
