4. Mobile sludge dewatering technology
MaskoFlex®
Mobile sludge dewatering technology
- Economically sustainable waste minimisation technology for a better environment
Mobile dewatering unit
Dewatering on site and return of the water to the source immediately.
High content of solids of the dewatered sludge.
Suitable for septic tanks.
Increases efficiency/number of tanks per kilometre driven less fuel, CO2 emission.
Less capacity needed on treatment plants.
>10 times more efficient than traditional vacuum units.
FlexLine danner grundlag for de øvrige modeltyper.
Udviklet med baggrund i ønsker og erfaringer fra kunder.
Design har vægtet tungt i udviklingen af modellen – unikt for JHL. 4

5. The operation, which takes approximately 3 minutes per m3, is quiet and relatively odour free as the unit is designed as a closed system
”The flow and environment in the septic tank is maintained as the dewatering is carried out on site, and the reject water is returned to the right septic tank during the operation. The JHL dewatering technology ensures continuity throughout the work day and therefore saves time and money” AQS Environmental Ltd, Ireland
”The MaskoFlex® unit empties septic tanks (2 m3) before unloading of the unit is needed”, ISS Denmark
