Improvement of wastewater treatment facility at instant noodle manufacturing plant for processing stability and odor reduction.
As a result of changing the existing aeration device in the adjustment tank to an Aqua Blaster and enhancing processing capacity, we achieved a reduction in normal hexane extractables and sludge!
To enhance the processing capacity of the oil and fat content, the existing aeration device in the adjustment tank was changed to an Aqua Blaster, resulting in an increase in processing capacity. As a result, the amount of normal hexane extractables was reduced by over 50% after passing through the adjustment tank, and other items similarly decreased, leading to a halving of the sludge generated during pressurized flotation. Previously, the pH on the inflow side tended to be acidic, requiring chemical neutralization; however, now, due to the effect of the Aqua Blaster, it has automatically become neutral, eliminating the need for neutralizing agents. Additionally, the dissolved oxygen (DO) level at the outlet of the adjustment tank has consistently been maintained at over 2.0 mg/L, resolving issues with sedimentation in the final settling tank, and the odor of dewatered sludge has changed from anaerobic to aerobic.
