APPLICATION OF UPFLOW BIOLOGICAL AERATED FILTERS PROCESS BY USING FLOATING FILTER GRANULAR MEDIA IN JAPAN
For floating filter granular media type nitrification-denitrification process, a pilot scale test was carried out for the purpose of applying for local wastewater treatment plants. From the results treated by holding a certain volume of wastewater influent to a reaction tank, the rate-limiting reaction of the present system was ascertained to be nitrification reaction. Further, it was confirmed that in the case of changing the daily volume of the wastewater influent, a good treatability could be obtained at a filtration rate equal to conventional biological aerated filter.
