Statiflo International is a world leader in the development and application of static mixers and associated technologies with thousands of customers in every process industry in over 80 countries.
Our headquarters are located in Macclesfield in the north west of England.
We also service industries throughout the world from offices strategically situated in the USA, Germany and Canada, as well as through our globally distributed network of agents.
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.
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.
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.
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.
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.
