## Overview

 

 

 





 

 



In the 90's, Veolia Water Technologies has developed a very rapid filter to enlarge its offer in opened and gravity filters, for drinking water production, particularly to match with the development of new big WTP around the world.  
Filtraflo™ TGV development came from dual-layer filters (Filtraflo™ DC type) rapid filtration feedback, and has been optimized with only one media layer : sand media  
  
Filtraflo™ TGV is actually the most advanced gravity filtration system and the most compact within the filtration Veolia Water Technologies offer :

- technology one sand layer (sand high : 2 m, velocity with N filters : 15 m/h, with N-1 filters : 20 m/h)
- technology dual layer sand / Anthracite
- technology dual layer sand / GAC
- technology dual layer sand / MnO2
- technology three layer sand / MnO2 / GAC or Anthracite
- Each filtration media type needs an appropriate backwashing mode management, with air + water sequences.

Veolia Water Technologies can deploy its Filtraflo TGV technology tailored to the following needs :

- turbidity and suspended solids treatment
- micropollutants treatment
- manganese treatment…

### Filtraflo™ Range

All Filtraflo™ filters employ the same basic principle that involves a rapid gravitational filtration of raw water through a granular media. The filtering bed is composed of single or dual media layers.

### FILTRAFLO™ Carb

Filtraflo Carb is a chemical free polishing solution involving micrograin activated carbon, that allows by adsorption the removal of the Natural Organic Matter, the pesticides, and a large spectre of micro-pollutants in treated water while also filtering it.
