The principle of the flotation technology marketed under the AS-FLOT trade name is based on a separation process that is employed to separate dispersed particles (solids or grease) from a liquid. During flotation, pollution particles agglomerate with air micro-bubbles producing flotation foam, which is lighter than water. The foam rises to the flotator surface, from where it is withdrawn to a storage tank.
Wastewater contains specific dissolved organic pollution that is manifested in high concentrations of the BOD 5 , COD, extractable substance, and solid substance indicators. The temperature also shows high fluctuations, mainly in water from meat production. Depending on the requirements for output parameters, we are able to design, deliver, and ensure the assembly and operation of not only mechanical pre-treatment, but also biological after-treatment. Biological after-treatment is applied in cases when water should be released into a recipient. Sewage is not subject to mechanical pre-treatment - flotation. After separate mechanical pre-treatment, it is directly routed to the activation part of the WWTP.
