Filters & Tools
Products to eliminate pollutants, odorous substances and biogenic corrosion
The fouling process of wastewater often starts as early as in the sewer or the force main. Causes for this include low flow rate, long residence time, high temperatures and low pH value. This results in the formation of hydrogen sulphide (H2S) – a toxic gas that causes unpleasant odours. On top of that, even low H2S concentrations can lead to concrete degradation. Sewage structures are thus destroyed, which results in high investment costs.
We have the products you need for immediate and effective pollutant, malodour, and corrosion control:
- Manhole biofilter
- Top filter
- Universal filter
- Pipe filter
- Pipe filter cartridge
- Sewer infiltration water barrier
- Air trap
- Odour and emission barrier
- Flexible segment valve
