Submersible Mixer Structure
Model Selection and Flow Field
The selection of a submersible mixer is a relatively complicated task. The correct selection directly affects the normal use of the equipment. The first principle of agitators model selection is to allow the submersible mixer to exert its full mixing function in a suitable volume. Generally, it can be determined by flow rate. According to the different process requirements of the wastewater treatment plant, the optimal flow rate of the submersible mixer should be guaranteed to be between 0.15~0.3m/s. If the flow rate is lower than 0.15m/s, the push flow mixing effect will not be achieved. If the flow rate exceeds 0.3m/s, it will affect the process effect and cause waste. Therefore, before selecting a model, we need to confirm following things about the wastewater treatment.
1. Places where the QJB submersible mixer will be used, such as: sewage pool, sludge pool, and biochemical pool.
2. Parameters of the wastewater medium, such as: suspended solids content, viscosity, temperature, and PH value.
3. The tank shape and size, wastewater depth and installation method of the agitators.
At the same time, energy saving factors should also be taken into consideration, because this will affect the user's future operating costs.
Finally, one or more submersible agitators should be used according to the specific situation.
