  • Depending on the nature of wastewater and the amount of suspended solids, from 30 to 60% of large and small inclusions of organic and inorganic origin are removed, which significantly reduces the load on all subsequent stages of water treatment.
  • Simple and reliable design. All parts are made of stainless steel AISI 304. Compact design, small footprint.
  • The drum filter element is made of wedge wire and has excellent hydraulic performance. In addition, this screen unit is more wear-resistant than other types of filter elements.
  • Does not require operator presence. The solids are discharged automatically. Continuous treatment allows reuse of up to 95% of water, which significantly reduces the costs of the entire complex. It is only necessary to observe and periodically remove the filtered and collected contaminants.
  • Mobility. If necessary, it can be easily reinstalled to another place.
