ECOMIX RW 00 900 Application areas The compact submersible mixers of the RW series have been designed for a wide range of applications. The units can, for example, be used for many mixing and stirring applications in sewage treatment plants and in industrial and chemical processes. The submersible mixers can be installed in all tank shapes and sizes. Depending on the requested intensity of mixing and flow formation, one or more mixers may be installed in a single tank. Installation ABS submersible mixers are generally installed using a universal guiding system which allows use of the unit at different water depths in a tank. Dead zones within a tank are therefore avoided. Using the ABS guide tube system it is a simple matter to raise or lower the mixer for maintenance purposes or for repair even when the tank is flooded. Selection In order to ensure optimum selection we ask for the following information: Purpose of application Tank shape Tank dimensions Medium to be mixed Viscosity, specific weight Temperature,drymatter content, etc Performance Curves Hz Mixer Selection System Velocity diagram

ECOMIX RW 00 900 The major advantage of horizontally operating submersible mixers in comparison to conventional mixers, is that they allow the possibility to direct the flow in different directions. This allows better optimization of the flow pattern in the tank. Depending on the location of the mixers we get different types of flow patterns which have different effects. In order to ensure the best arrangement for an effective energy saving mixing operation in the various types of tanks, the positioning hints in the sketches below should be carefully considered. Round Tanks 0.5 d 0.5 d 7 0 d d The rotating flow formation is the simplest type of flow. It is an effective method to mix materials with a high drymatter content, as a high flow velocity is established after a relatively short running time. It should be noted, however, that heavier particles may be deposited on the floor in the center of the tank Effective thorough mixing in a round tank, without rotation of the material, can be achieved if the submersible mixer is setup at an angle of 7 to 0 to the center line of the tank. The height of liquid in the tank should be within the ratio 0. to times the tank diameter. Rectangular Tanks Rectangular tanks can be effectively mixed if the mixers are installed as shown in the illustration below. When using a mixer the length/width relationship of the tank should not be greater than 5. Otherwise a number of mixers should be installed. Optimum energy usage is achieved if the length/width ratio does not exceed.5. L 0.

ECOMIX RW 00 900 RW 00 in pump stations The RW 00 mixers are mainly used for mixing applications in pump sumps. The function of the mixer is to thoroughly mix up the contents of the sump before the pumps themselves start up, so that after completion of the pumping only a small amount of deposit remains. Silting up of the pump sump is therefore effectively avoided. In addition this mixer can prevent the formation of floating crusts in pump sumps. In general the operation of the mixer in the pump sump is controlled as follows: The mixer is operated by a level control unit which switches it on shortly before the pumps themselves are switched on. In general a timer allows 0 to 45 seconds mixing before starting of the pumps. An additional level control unit switches off the mixer while propeller coverage of 0 to 40 cm remains.
