    The Aquazur V is a descending current open sand filter designed for drinking water and wastewater treatment. It filters suspended solids using a thick layer of homogeneous sand, allowing high filtration speeds. It washes efficiently in three steps without turbidity peaks. Operation is easy as it does not require measuring individual filter flows. The Aquazur V is suitable for drinking water treatment and municipal wastewater tertiary treatment for suspended solids and phosphorus removal.

    Aquazur V ®

    open sand filtration


    drinking water & urban wastewater

    a high speed and performant


    sand filter with multiples
    advantages

    efficient washing system


    no turbidity peak due to no overload when washing the
    other filters

    easy operating control


    no need of filter flow measurement

    Designed for drinking water plants, Aquazur® V is a descending current open


    sand filter. It retains suspended particulate matter in raw water thanks to a thick
    layer of sand. The homogeneity of the sand increases the filter run time, while
    the thickness enables filtration at high speeds and the high water head (1.20 m)
    prevents degasification.

    The Aquazur® V is typically used for drinking water treatment line: coagulation,
    separation, filtration and can be also used after decarbonatation in a Densadeg®.
    The Aquazur® V is also highly suitable for municipal wastewater tertiary treatment
    regarding suspended matter and phosphorus removal. This type of tertiary filtration
    is particularly interesting to improve any downstream disinfection process (U.V.,
    chlorination, etc.)
    operation
    filtration
    The unfiltered water, distributed to the filter by the inlet weirs, enters 3 Rinsing by backwash with filtered water at 13-15 m/hr, with a crosswash
    over the sand. It crosses through the sand, where suspended solids of 7 m/hr.
    are retained. Filtered water is evenly collected by the floor nozzles.
    The chamber below this floor is connected to the filter outlet, usually The overall duration of washing ranges from 10 to 12 minutes, with water
    by a filter controller. From the outlet, the water is conveyed to lasses amounting to 4 to 5 m3/m2 of filter area, only 2 m3/m2 of which is
    subsequent treatment steps. During filtration, sand gradually clogs filtered water.
    the filter. When a preset degree of clogging is reached, filter washing
    must take place.
    operating control
    washing in three steps
    The major control parameter is the degree of sand clogging, which commonly
    determines when whashing is necessary. Filter flow measurement is not
    1 Lowering of the water level to the washout weir.
    necessary, as the various filters deliver the same flow, evenly split by the inlet
    weirs. Filtered water turbidity is usually monitored at the outlet of the filter
    2 Filtered water backwash at 7-15 m/hr combined with air scour
    battery and not for each individual filter.
    at 50-60 m/hr and crosswash with unfiltered water at 7 m/hr. A
    perfectly even distribution of water and air scour is achieved by
    the special design of the nozzles.
