      • Static mixers designed specifically to meet the special requirements of the global desalination industry.

        The Statiflo DSM provides the highest mixture quality with minimum dosing of additive(s), eliminating overdosing to enhance downstream separation efficiencies and membrane lifespan. The requirement for dosing lances with small additive release holes, aided by internal baffles, has been eliminated.

        The Statiflo DSM has been independently tested for pressure drop and mixture quality (variation coefficient, CoV) by BHR Group, world leaders in fluid engineering, research & consultancy. Mixers have been tested at industry realistic fluid velocities and additive ratios and demonstrated to achieve better than industry standard mixture quality. 

        Applications

        Pre-treatment applications for minimising biofouling, sealing and membrane plugging:-

        • Inlet blending
        • pH control
        • Disinfection
        • Anti - scalant
        • Coagulation
        • Flocculation 

        The very latest techniques for design and modelling have been used to develop the Statiflo DesalMixer (DSM) for turbulent flow dosing and blending applications in the pre-treatment and post-treatment stages of desalination processes.

      • The Innovative Gas Dispersion System: Custom Designed, Engineered and Built

      • The Statiflo Gas Dispersion System (GDS) is a totally new concept for simultaneous mixing and mass transfer.

        The Statiflo GDS is designed to overcome the difficulties associated with the use of a single static mixer. The system uses two different mixers, the first, in a sidestream, to form small gas bubbles and the second, in the main line to provide contact time and efficient mass transfer. As the gas bubbles are formed in a constant velocity sidestream, the gas bubble size is constant and independent of any variations in the main liquid flow.

        Typical applications:

        • Aeration of drinking water for iron, manganese and carbon dioxide removal
        • Ozonation of drinking water and waste water
        • Carbonation of mineral water
        • BOD and COD reduction
      • Statiflo Chemical Dosing Lances

      • Statiflo chemical dosing lances are custom designed and engineered to maximise the efficiency of Statiflo's static mixers. They are also available as standalone products for all of your chemical dosing requirements.

        Feature and benefits:

        • Ensures correctly distributed flow around mixing elements.
        • Custom designed for each application
        • Available in a variety of materials, including plastics and exotic alloys, eg. Hastelloy
        • Withdrawable under pressure
        • Available with a variety of different pressure ratings depending on your requirements.
        • Ensures safe and predictable dosing operation.
      • Channel Mixers

      • Statiflo's Channel Mixers are revolutionising the design and operation of water and waste water treatment plants.

        Statiflo Series 900 Channel Mixers rapidly achieve a high degree of mix with extremely low headloss in very short lengths.

        Complete mixing in the channel is possible, achieving a low CoV, over a wide range of flowrates. With headlosses of just a few millimetres feasible, gravity flow is an option, eliminating the expense of pumping, saving not just capital costs, but ongoing maintenance and energy costs too.

        Statiflo Channel Mixers can be installed in new treatment works or easily retrofitted into existing installations, even when flooded and live. The modular design concept, based on the STMC mixing elements, allows wide variations in aspect ratio (height/width) suitable for square or nearly square channel sections, narrow deep channels and wide shallow channels. Independent trials have established that the STMC concept is the most efficient of all known commercially available static mixers.

        Open channels can develop unusual velocity profiles not found in conventional piping systems. Statiflo has invested considerably in developing a procedure to ensure that the correct amount of additive is injected proportional to the local mainstream flowrate.

        Applications include:

        • Raw water blending
        • pH control
        • Rapid coagulant addition
        • Polyelectrolyte dosing
        • Residence time control

        The high efficiencies and benefits of the channel static mixer apply to any scale, the largest installed to date is 7m wide x 5m deep, handling 7 tonnes/sec of water.

      • Wastewater Mixers

      • Statiflo Non-Ragging Pipe Mixer (NR)

        The Statiflo NR Mixer has been specifically designed for sludge mixing or wastewater applications with high fibre content.

        In full-scale trials with a major UK water utility the Statiflo NR Mixer outperformed all competitor's designs including a static mixer, an orifice plate and sludge valves.

        These pictures and graphs illustrate the superior performance of the Statiflo NR Mixer compared with a competitor's mixer.  The graph  shows the typical effects of ragging with increasing headloss and reduced flow until the competitor's mixer ceased to operate in less than four hours.

        Statiflo Non-Ragging Channel Mixer (NRC)

        A non-ragging static mixer for dosing additives into wastewater including raw sewage.  The Statiflo NRC Mixer has been designed specifically for P removal applications but can equally be used on any chemical dosing service on raw sewage where non-ragging properties are essential.  It has a unique variable geometry custom designed for the widest range of wastewater velocities and channel depths found on a typical wastewater treatment plant.

        Statiflo NRC Mixers have been installed since 2008 and have consistently remained rag free and have required no maintenance.
