Inline Static Mixers are used in the Municipal and Industrial Water Treatment Process

Inline Static Mixers & Inline Mixing: The demands for precise and responsive chemical dosing in the treatment of drinking water is growing. Applications such as disinfection, flocculation, fluoridation, plumbosolvency, control of taste and odour, ph correction, turbidity, ozonation to name but a few require precise metering of chemicals.

Not only does this require the precise metering of chemicals to meet process demands, stringent levels of residuals, but also to perform when operating in a variety of flow conditions. Therefore there is a need to shorten process times and to ensure that any analysers/sample probes are measuring a representative sample after chemical dosing.

To assist in this process Statiflo inline mixers for water treatment can be supplied complete with chemical injection lances which direct the chemical into the heart of the mixer for optimum performance of the mixer.

The inline mixing and correct dosage of these chemicals has a fundamental influence on each stage of the treatment process and ultimately the complete process itself. So often site conditions do not provide the high level of mixing and process times to meet the prerequisite conditions. The use of in pipe or channel static mixers provides the required level of mixing so that optimum chemical dosing is achieved.  Thereby saving chemical, improving the performance of the treatment process as well being able to operate in a variety of conditions and flows encountered in todays treatment processes.

With modern advances in water treatment the use of powerful oxidants such as ozone and AOP processes (Advanced Oxidation Process) are not uncommon. Ozone is a strong oxidising compound which rapidly oxidises organic materials, iron, manganese and other substances when it is added to drinking water. In addition, it is an extremely effective disinfectant against bacteria and viruses. Ozone is very unstable and therefore has a short life. It is therefore essential that the ozone is mixed and dispersed into the water as soon as possible. Statiflo static mixers and gas dispersion systems are ideally suited for this application and there are many installations worldwide.

Static mixers have gained in popularity, as unlike stirred tanks the complete water flow and chemicals are subject to complete and thorough mixing in a relatively short period of time. The required energy for mixing is taken from the main water flow. The resulting headloss is very low and will depend upon the operating conditions and the design of the chosen mixer. Statiflo have considerable experience in designing and selecting the right mixers for the acceptable and calculated head loss.
