LG replaces ozone supplier to Primozone

In LG Chemicals facilities in Ochang, South Korea they manufacture electric car batteries and film for display panels. They are using ozone to treat wastewater to reduce COD from 300 ppm to 100 ppm. They have two water treatment facilities and each water treatment plant using six GM48. Each water treatment plant water capacity is 70 m3/hr.

Before, LG Chemical used a different ozone generator for their wastewater treatment. Due to too many technical issues during four years of operation, LG decided to replace the old ozone generators. With six units of GM48 from Primozone in one of the wastewater treatment plants, they were really satisfied with the Primozone solution. In the following year they exchanged to another six units of GM48 in their other wastewater treatment plant. For power consumption was similar with former ozone generators but they reduced 30% of LOX expenses. Still Primozone generators are working well on the sites.
