AVF Technology

Automated Variable Filtration (AVF) technology is a State-of-the-Art technology in which upward flow of influent is cleaned by downward flow of filter media. During the process itself, the filter media is cleaned by the filtered influent itself, thus there is no requirement for any additional filter media cleaning process or fresh water. The AVF process utilizes a proprietary system of continuously cleaned descending bed filters deployed in a variable array. The system normally operates in series for production of highest quality filtrate by double pass filtration. The key benefits of the system are:

  • Higher solids capacity
  • No moving parts
  • Low pressure drop
  • Continuously cleaned media beds
  • Elimination of ancillary equipment
  • Even flow distribution
  • Lower operating and maintenance costs
  • Cost effective to install
  • Fraction of the cost of low pressure membranes
  • Average reject of 5-15%
  • Extremely low power consumption
  • Protection against waterborne diseases
  • Ease of Operation & Maintenance

APPLICATIONS of AVF

  • Municipal Drinking Water
  • Municipal Wastewater Treatment
  • A Broad Range of Industrial Applications
  • Wastewater Recycling and Reuse
  • Protection of Environmentally Sensitive Watersheds and other Phosphorus Restricted Basins
  • High Quality Pre-filtration for Membrane Processes
    and Desalination
