Denitrification deep bed filter is a gravity flow biological filter that integrates filtration and denitrification, which can efficiently remove suspended matter (SS) and nitrate nitrogen (NOx-N). The T-type filter brick of denitrification deep bed filter combined with the arrangement gas pipe can replace the old backwashing process of deep bed filter (filter plate + long handle filter cap). The characteristics and advantages of the filter brick are as follows:

Features:

1.A secondary distribution tank is set to improve the uniformity of water distribution and break through the limit of filter width to meet the needs of the process;

2.Reasonable arrangement, increase the uniformity of air distribution and water distribution and filter brick axial distribution length, improve the effect of air distribution and water distribution.

Advantages:

1.Carbon source and fixed biofilm combination, no sewage backflow, save power, improve denitrification rate, reduce denitrification filter volume;

suitable for sewage treatment and upgrading, high efficiency, low energy consumption;

2.After the introduction of activated sludge process, a combination of physical filtration and biological oxidation, exquisite structure.
