  • Flomar®
    Flomar®

    Inorganic flocculant
    Polyaluminium chloride hydroxide 18% Al2O3
    FLOMAR®® 200 is a liquid inorganic flocculant, completely miscible in water, whose active principle is constituted by a polymer complex of hydroxy-aluminium ions.

    Properties
    FLOMAR® is supplied in aqueous solution in order to simplify transport, storage and dosage. Its advantages compared to traditional flocculants (ferric chloride and/or aluminium sulphate) are:
    • Higher flocculant power, due to the formation of larger flakes, with a resulting higher sedimentation rate
    • More easily filterable decanted mud
    • High effectiveness in a wide pH range, which makes the use of neutralizing agents, such as caustic soda or lime, unnecessary
    • Lower decrease in treated water pH
    • Higher reduction of turbidity with the same active principle expressed as Al2O3, with consequent saving of reactive
    • ood performance at low temperatures
    • In case of overdoses, an increase in the turbidity of treated water is not to be reported, therefore making it suitable for water, whose suspended solids content varies suddenly and casually
    • Besides the clarification, there is also a drastic abatement of COD and of phosphorus concentration in treated water

    Areas of application
    The high concentration of aluminium makes FLOMAR® particularly suitable for the treatments of industrial and civil waste water treatments, as well as for the processes of sizing in the paper industry.
    Moreover FLOMAR® is compliant with the “Type 1” category of the European Standard EN883: 1997 (Chemicals used for treatment of water intended for human consumption - Polyaluminium chloride hydroxide and Polyaluminium chloride hydroxide sulfate), as well as with the technical specifications of the UNICHIM C-5 Technical Sheet - Chemicals used for treatment of water intended for human consumption “Polyaluminium chloride hydroxide sulphate”, therefore it can be used in water treatment plants with excellent results.

    Conditions of use
    FLOMAR® can be dosed as is or diluted. In this latter case, the dilution water should always be demineralized or distilled.

    Stability
    FLOMAR®, if properly stored, can be considered stable over time. It is recommended, however, in order to retain all the properties of the product, to carry out a thorough cleaning of storage tanks at least every 12 months. It is also good practice not to keep the product for periods longer than six months.
    It was observed that certain substances present in the plastic (PE or PP) of new containers intended to contain FLOMAR® may in some cases trigger a crystallization process of the product, with the formation of a white drag that settles on the bottom of the container. The formation of this precipitate, which however does not alter the characteristics of the product in any way, can be avoided by using containers that have already contained the product or that have been cleaned up with a diluted solution of hydrochloric acid.

    Production process
    FLOMAR® is produced through a completely inorganic dedicated process based on acid digestion of Al(OH)3. Only demineralized water is used, and all the other raw materials are obtained by using inorganic processes, therefore FLOMAR® is completely free from organic impurities.

    Packaging, storage, handling
    FLOMAR® is supplied in tankers from 12 to 28 tons.
    All equipment in contact with the product, from storage to dosage, should be in acid-resistant material.
    For handling and any other information concerning users’ safety and health, please refer to the Material Safety Data Sheet, which should be peremptorily requested at the time of the first order.
