The world’s largest static mixer? W


hat is possibly the largest static mixer in the world is nearing


completion before dispatch to Hong Kong.


The Statiflo STMC mixer, which is 8.5m wide x 7m high and


weighs 18 tonnes, will be installed in a final effluent channel to ensure that sodium hypochlorite solution will be uniformly dosed to give a high mixture quality with a Coefficient of Variation (CoV) < 0.05.


Even at the


maximum flow of 4.15 Mm3


/day (48m3 /


sec) the headloss across the mixer will be only 130mm. The Statiflo


supply includes the dosing lances which are positioned immediately upstream of the mixing elements and the mixer has been pre assembled in order to provide


trouble-free installation once it is on site.


The advantage of this and other static mixers in the Statiflo static mixer range is that they are maintenance-free, require no spare parts and have a low carbon footprint as the headloss is very small.


The Statiflo range extends to pipe mixers with various mixing element designs to suite the application, gas dispersers for the efficient dispersion of gases like ozone for water treatment and a full array of custom designed static mixers for the process industries. l

Intelligent valve reduces pipework T


he ideal valve for use in a hygienic processing environment is easy to clean using clean-in-place (CIP), contains a low internal volume and a minimum number of connections as well as offer super precise flow control abilities. These exact criteria were used to design the Robolux valve from Bürkert, a space saving, intelligent field device which is suited for use in pharmaceutical, chemical, food and beverage processing. Hygienic processing places high demands on the reliability and cleanability of production facilities.


Common challenges, such as corrosion in pipe systems, valve


manifolds and tank installations in different pharmaceutical, chemical and biotech facilities, for example, can be cut, thereby reducing costs and improving plant availability. The Robolux valve has two independent process switching functions achieved with one membrane. This reduces the installation space requirement, eliminates T-adapters and minimises the overall number of valves and membranes required. The multi-port membrane valves were designed for high- purity installations and make it possible to design complex systems that are considerably more compact than those using conventional fluid control valves.


The design of the valve is also intended to minimise the internal volume and produce no dead flow zones.


In addition to improved flow and evacuation, both cleaning and changeover of the interfaces for the manufacture of other products is easier and faster, with less wastage of expensive chemicals and ingredients.


This technology makes it possible to replace two traditional shut-off diaphragm valves and at the same time eliminate all dead legs and one tee-piece with one single valve. l
