Results of the study on the treatment of wastewater from cleaning heavy fuel oil tanks using inorganic powder coagulants.
Easily reduce COD Mn and n-hexane extractable substances! It is possible to obtain colorless and transparent treated water.
We would like to present an overview of the results of treatment tests conducted using special adsorbents and the inorganic powder coagulant "Super Namit" for the wastewater from the fuel oil tanks of a thermal power plant. The concentrations of oil and COD components were lower than expected; however, after performing adsorption treatment with the special adsorbents "CS-05" and "NAC-01," we were able to easily reduce COD Mn and n-hexane extractable substances by using our product for coagulation treatment. We were able to obtain colorless and transparent treated water. 【Treatment Conditions】 ■ Added 0.3% of the special oil adsorbent CS-05 and stirred for 10 minutes. ■ Added 0.5% of the special powdered activated carbon "NAC-01" and stirred for 10 minutes, then added 500 ppm of "TN315NY-T3," stirring vigorously for 1 minute and gently for 2 minutes to form flocs. ■ Filtered this using ADVANTEC No.5A quantitative filter paper and requested analysis from a measurement certification facility. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Processing Results】 ■ The raw water was brownish and turbid, neutral, with a COD Mn of 32.7 mg/L, and contained 78 mg/L of normal hexane extractable substances. ■ The treated water became colorless, transparent, and odorless, with a COD Mn of 20.2 mg/L, and the normal hexane extractable substances were reduced to below 2 mg/L. *For more details, please refer to the PDF document or feel free to contact us.
