Continuous operating wastewater treatment plant based on the precipitation flocculation principle combined with a DAF-based flotation system for water clarification on industries like Chemicals, Detergents, Automotive or Vegetable Processing. VAMEF includes all the chemical reaction components, such as chemical agents dosing units, automatic reaction pH control, and stirred reaction vessel. The flotation unit has all the standard components. VAMEF models come in two basic principles, circular flotation reactor, which carries a circular central engine scraping arm, and a more traditional shape, with a rectangular flotation chamber which carries a come-and-go chain scraping bridge, for the larger models, such as the R ones.
