Improvement of the performance and the safety of the Dongsuh food facilities thanks to the HYDREX™ range of water treatment chemicals and associated services
Dongsuh Food was founded in May 1968 and has been producing Maxwell House instant coffee since 1970. Thier main business is the manufacture and sale of food & beverages and agricultural products. The company is headquartered in Seoul, Mapo-gu Dongsuh building, with plants located in Bupyeong, Changwon and Jincheon.
The wastewater treatment within the manufacturing process is organized as follows: coffee process – 2 lines (500 m3/day & 1,800 m3/day); prima process: 500 m3/day.
The Dongsuh Food team needed to use chemicals in wastewater treatment which optimize both operational and economic aspects. At the same time they had to reduce air pollutant emissions during sludge incineration.
- Based on jar-test results on the produced wastewater, the chemical Hydrex was chosen
- Chemical consumption was reduced through precision control and accurate dosing
Veolia Water Technologies proposed the most suitable chemical program based on the test results, and now provides Dongsuh Foods with the Hydrex-
6135, 6310, 6752 chemicals for their wastewater treatment process.
- Cost reduction
- Reduced chemical consumption
- Improved flocculation efficiency
- Reduced energy consumption
- Regulatory compliance
