Dissolved air flotation plants for the treatment of industrial waste water Lugan® flotation plants further treat waste water resulting from wash processes, for instance from the wash stations of vehicles.  After a pretreatment in a separation plant they remove emulgated oils and fats as well as heavy metals.
The plants have proven themselves in a variety of industries, from the food industry to wash stations, and fulfilled the requirements of many different applications, from individual plants for an indirect return to the environment to recycling, as well as pretreatment for biological plants.
The post-treatment of waste water ensures that it meets the requirements regarding pH values, hydrocarbons, lipophilic materials and heavy metals.  COD and BOD values are significantly reduced.
