[Anaerobic wastewater treatment system case study] Nakata Foods in the food industry

We will introduce a case where bioimpact was implemented to achieve high-efficiency energy recovery.

Nakata Foods is a food manufacturer in Wakayama Prefecture that specializes in the production and sale of pickled plums, plum wine, and plum processed products. The plum seasoning wastewater generated during the pickling process is an extremely high-concentration wastewater exceeding BOD: 100,000 mg/l, making it difficult to treat with conventional wastewater treatment facilities. To utilize the plum seasoning wastewater as a biomass resource, we introduced our anaerobic wastewater treatment facility, "Bio Impact." Previously treated as industrial waste, the plum seasoning wastewater can now be processed at a lower cost due to the high-efficiency anaerobic wastewater treatment facility. This has significantly reduced the burden on small and medium-sized businesses by allowing for acceptance at a more affordable cost than before. 【Facility Overview】 ■ Facility: Nakata Foods Biogas Power Plant ■ Start of Operation: April 2019 ■ Treatment Capacity: 20 tons/day (dedicated to plum seasoning wastewater generated from our own and local plum processing businesses) ■ Biogas Utilization Equipment: Diesel engine generators (60kW x 6 units) ■ Annual Power Generation: Approximately 2 million kWh ■ Treated Water: Utilizes public sewer system *For more details, please refer to the PDF document or feel free to contact us.
