Main Features

1.    High packing density of membrane components and low investment per unit membrane area 
2.     Compared with reverse osmosis, it has a higher permeation flux under high salt and low pressure conditions 
3.    Can intercept impurities through effective ingredients; It can also intercept effective ingredients through salt and other impurities 

Application Cases

1. Amino Acid Production Line:

Applied in a large-scale amino acid factory in Shandong, China. It realized 95% decolorization of L-lysine fermentation broth, reduced salt content by 88%, and increased product purity from 82% to 99.2%, while reducing energy consumption by 30% compared with traditional processes.

2. Natural Sweetener Processing:

Used for stevia extraction in a food additive company in Zhejiang. It separated steviol glycosides from impurities such as sugars and colloids, increasing the active ingredient content from 40% to 90%, and the product meets international food safety standards.

3. Pharmaceutical Intermediate Purification:

Deployed in a pharmaceutical enterprise in Jiangsu for the purification of cephalosporin intermediates. It removed 92% of inorganic salts and by-products, shortened the subsequent refining cycle by 40%, and improved the total yield of finished drugs by 15%.

4. Beverage Industry Concentration:

Adopted by a fruit juice processing plant in Guangdong. It concentrated natural fruit juice (orange juice, apple juice) at low temperature, retaining over 98% of vitamins and flavor substances, and increasing the sugar content from 12°Bx to 45°Bx without thermal damage.

5. Industrial Wastewater Treatment:

Installed in a printing and dyeing factory in Hebei. It decolorized printing and dyeing wastewater with a decolorization rate of 90%, reduced chemical oxygen demand (COD) by 75%, and the treated water can be reused for production, saving 50,000 tons of water annually.
