LG Chemicals Uses Primozone
Objective
Implement a reliable ozone-based wastewater treatment system at LG Chemicals in South Korea to reduce COD levels from 300 ppm to 100 ppm, improve operational stability, and lower operational costs compared to the previous ozone generators.
Primozone solution
12 x GM48 ozone generators
In Ochang, South Korea, the LG Chemicals facility produces electric car batteries and display panel film. To ensure sustainable operations, the company uses ozone for wastewater treatment, reducing COD (Chemical Oxygen Demand) from 300 ppm to 100 ppm. Each of the two water-treatment plants on-site has a capacity of 70 cubic meters per hour and operates six GM48 ozone generators.
After four years of using another brand of ozone generator, LG Chemicals experienced technical issues that prompted a search for a more reliable solution. The company replaced the existing units with six Primozone GM48 ozone generators in one wastewater treatment plant. Impressed by the performance, LG Chemicals added another six GM48 units in the second plant the following year.
While the GM48 ozone generators showed similar power consumption to the previous machines, LOX costs were reduced by 30%, demonstrating both efficiency and cost savings. Today, the Primozone GM48 units continue to operate reliably at LG Chemicals, supporting sustainable and effective wastewater treatment.
