In recent years, efforts to address environmental issues have become an integral part of corporate activities. In order to achieve zero emissions (zero emissions), advanced treatment is required, and running costs such as equipment costs and maintenance and management costs will be incurred. How to keep running costs down is an issue for sludge treatment. At our company, we have achieved a reduction of approximately 75% of excess sludge without emitting "exhaust ozone" by using ozone for complete reaction. The sludge volume reduction device "NIIKURA Onitoji" can reduce and reduce the running cost, which has been a big burden until now, by significantly reducing excess sludge.
In addition, ozone can be used to decolorize wastewater, and it can also be used as a COD countermeasure for biogas power generation.
