Leiblein - Floatation Wastewater Clarifier
In addition to non-sedimentable solids and floating materials such as oils and fats, the flotation clarifier also efficiently separates precipitated materials such as suspended solids from liquids. This makes this flotation system particularly suitable for the treatment of process or waste water, which has very high purity requirements.
The flotation clarifier is based on the flotation separation method. By using micro-bubbles, the contaminants float up in the flotation system and are removed at the surface. The microbubbles in the flotation clarifier are generated by the MicroGas™ microbubble generator. In contrast to conventional technologies, such as dissolved air flotation (DAF), this is not based on the principle of gas dissolution, but on the direct induction of microbubbles. Additional lamella packages provide a significantly larger clarification area, allowing even heavier suspended solids to float efficiently.
The combination of the innovative MicroGas™ technology with effective lamella packages provides an excellent flotation result.
- Large clarification area due to lamellas: powerful, high throughputs and compact design
- No recycling stream required for microbubble generation as with dissolved air flotation
- Few components, therefore minimal space requirement
- Easy to install, operate and maintain
- Avoidance of downtimes due to pump or nozzle failures (e.g. due to solids from overflow)
- Energy efficient: Minimum energy consumption < 0.05 kWh/m³
- Low operating costs
- Independent of temperature and pH value
- Adjustable gas flow rate; adjustable bubble size and bubble volume
- Stronger separation efficiency through chemical pre-treatment
The flotation clarifier is particularly suitable for applications that require a high level of purity. It is mainly used for process and wastewater treatment in the food and petrochemical industries.
