MaskoFlex®

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.

Mobile sludge dewatering technology- Economically sustainable waste minimisation technology for a

better environment

”The MaskoFlex® unit empties 60-70 septic tanks (2 m3) before unloading of the unit is needed”, ISS Denmark

”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 operation, which takes approximately 3 minutes per m3, is quiet and relatively odour free as the unit is designed as a closed system
