What is Alkaline Recovery?

Alkaline recovery is the process of reclaiming and reusing alkaline solutions, often found in industries like wastewater treatment and chemical manufacturing. This process helps reduce operational costs and minimize environmental impact by preventing the discharge of harmful chemicals.
Membrane separation technology is instrumental in alkaline recovery, employing advanced filtration methods such as reverse osmosis, nanofiltration, and electrodialysis to selectively remove contaminants from alkaline solutions. These membrane technologies enhance the efficiency and effectiveness of recovery, allowing for higher purity and concentration of the alkaline solution, which can then be reused in industrial processes.

We specialize in the application of advanced filtration methods, including reverse osmosis, nanofiltration, and electrodialysis, to optimize alkaline recovery. These membrane technologies ensure the efficient separation of contaminants, enabling the production of high-purity, concentrated alkaline solutions ready for reuse in industrial processes.
Spiral Wound Nanofiltration (NF) Membranes
Spiral Wound NF technology are used for selective separation, allowing smaller ions and molecules to pass through while retaining larger contaminants. This process is effective for recovering alkaline solutions with moderate salinity, providing a high recovery rate with minimal energy consumption.
Electrodialysis (ED)
Electrodialysis uses an electric field to move charged particles through ion-selective membranes, separating positive and negative ions from the alkaline solution. This method is particularly useful for concentrating and recovering alkaline solutions in applications where ion removal is crucial.
What is the Chor-Alkali Industry?

The chlor-alkali industry is responsible for producing key chemicals like chlorine, sodium hydroxide (caustic soda), and sodium carbonate. These chemicals are essential in various industries, such as water treatment, paper, textiles, and chemicals. The primary process used in the chlor-alkali industry is the electrolysis of salt (sodium chloride), which separates it into chlorine gas, hydrogen gas, and sodium hydroxide solution.
In the chlor-alkali industry, the softening process is typically used to remove hardness-causing ions, such as calcium and magnesium, from water used in electrolysis. This is important because hard water can scale and damage equipment, reducing efficiency. Softening is usually achieved through the addition of lime (calcium hydroxide) or soda ash (sodium carbonate), which reacts with the hardness ions to form insoluble precipitates that can be removed by sedimentation or filtration. This ensures that the water used in the electrolysis process remains clean, helping maintain equipment performance and prolonging the life of the plant.
