Automated Operation

Optimized membrane system enables automated operation with very easy maintenance.

Food Industry Application

Applicable to kimchi manufacturing, food desalination, and microbial separation.

No Chemicals Required

As a product manufacturing process where chemicals cannot be used, the membrane system is the optimal solution.

Competitive Advantage

Reducing salt usage in the brining process lowers production costs and is expected to boost exports.

Significant Waste Reduction

NF separation reduces brine waste to approx. 1/10, cutting treatment costs and required facility space.

Groundwater Savings

Brine reuse significantly reduces groundwater consumption, delivering cost savings.
