[Case Study on Wastewater BOD and Sludge Reduction] Ricoh Company, Ltd. Ebina Factory
We will introduce a case study of a lab test for reducing excess sludge treatment costs!
We would like to introduce a case study of a laboratory test conducted at Ricoh's Ebina Plant to reduce excess sludge treatment costs. As a result of three BOD comparison tests, an average reduction of approximately 20% in BOD was confirmed. In this test, the wastewater was diluted by half. However, in actual use, since the entire wastewater is modified, a BOD reduction of about 40%, which is double the test results, can be expected. 【Method of BOD Laboratory Test】 1. Collect 1 liter each of inflow and outflow water from Ricoh's Ebina Plant. 2. Divide the inflow into 500ml portions, labeling them A and B. Similarly, divide the outflow into 500ml portions. Further, modify inflow A with BW (Bio Water). 3. Mix inflow A with outflow A, and inflow B with outflow B (since it's 500ml each, the ratio is 1 to 1). 4. Measure the BOD of the BW-treated water and untreated water (using the 20°C 7-day incubation method). *For more details, please refer to the PDF document or feel free to contact us. *The section titled 'Reason for Interest' displayed during the PDF download is generated by AI from Ipros Inc.
