TDFC proposes techniques that allow for the removal of the suspended solids (organic as well as inorganic) from the water and for the refining of the treatment process in order to achieve a final fine-removal of the pollutants. These techniques are high-pressure sand filtration and carbon-activated absorption towers. Sand filtration occurs under high-pressure on a multi-layer filter bed. Filtering media specific for each layer assure complete removal and easy backwashing operation. The system is completely automatic and self-cleaning, in order to guarantee the highest operational reliability. For further removal of organic pollutants, TDFC employs absorption towers. In these devices organic compounds are absorbed by the surface carbon granules and thus removed from the water.       << Back
