[Asia Economy Yeongnam Reporting Headquarters Reporter Kang Woo-kwon] Gimhae City in Gyeongnam announced on the 14th that the Urban Development Corporation achieved cost savings of 530 million KRW through improvements in 15 facility processes. Along with this, they also realized system improvements that can increase daily wastewater treatment capacity by 200㎥.

Based on long-standing operational know-how at the livestock manure treatment plant, they promoted revolutionary process improvements and completed a total of 15 process enhancements, enabling treatment capacity to increase from 200 tons per day to over 400 tons.

According to Gimhae City, operating costs were reduced by 230 million KRW in 2019, and this year’s expected budget savings amount to 300 million KRW, resulting in total savings of 530 million KRW.

Additionally, since June, by applying a method that changes the external carbon source input technique using the characteristics of wastewater treatment microorganisms, they derived innovative budget-saving measures such as a 35% reduction in sludge generation and a 40% reduction in external carbon sources. This has led to an additional annual budget saving effect of approximately 400 million KRW.

At the public livestock manure treatment facility, to create a pleasant working environment, the odor prevention facility was improved with a high-efficiency three-stage chemical treatment method. Furthermore, by discovering new odor reduction agents and applying the new aerobic oxygen method for odor reduction technology, additional odor reduction at the site was achieved, receiving favorable reviews from external visitors.

A representative of Gimhae City Urban Development Corporation emphasized, "The excellent example of our staff’s high operational skills and continuous improvement of wastewater treatment costs will be shared and disseminated to similar facilities nationwide to serve as a good model for enhancing technological capabilities in similar environmental facilities, and we will strive even harder."
