  • Oxy - Filters

    The DynaSand Oxy filter works according to the same continuous process principle as the tried and trusted conventional DynaSand filter. The aeration of the filter bed is the major difference in the process. A biologically activated filter is generally equipped with air nozzles in the filter bed. The nozzles are difficult to reach and tend to ...

  • DynaSand - Model Oxy - Nitrification Filter

    The water which is to be nitrified is admitted into the DynaSand filter through the inlet distributor. As the water flows upwards through the filter bed, ammonia (NH4+) is converted into nitrate (NO3-) by bacteria Nitrosomonas and Nitrobacter - which form a layer on the surfaces of the filter grains. The bacteria, which are autotrofic and thus ...

  • DynaSand Deni - Filter

    Just like in a conventional DynaSand filter, the water to be denitrified is admitted into the filter through the inlet distributor. As the water flows through the filter bed, nitrite (NO2) and nitrate (NO3) are converted into nitrogen (N2) by a layer of micro-organisms formed on the surfaces of the filter grains. The nitrogen is discharged from ...

  • Deni - Denitrification Tank Filter

    Denitrification is generally performed in activation tanks. However, in many cases it is practical to partially denitrify the fluid in a DynaSand filter, the so-called DynaSand Deni. The denitrifying bacteria do not require oxygen - the filter bed therefore does not have to be aerated. External carbon sources must be added for denitrification, ...

  • DynaSand - Filter

    Simplicity, reliability and ruggedness are the main features of the DynaSand filter. The function of the DynaSand is very simple: the feed is introduced in the lower end of a media bed and filtration takes place upwards. The lower end of the media bed separates the dirt particles, and is selectively and continuously removed from the bed by an ...
