News: Dewatering tech helps environment

ADC invested heavily in clever new polymer de-watering equipment from Denmark. The result makes specialist drain clearance faster and far less of an impact on the environment, with a fraction of waste now going to landfill.
Moos de-watering technology
European search for innovative technology
ADC (East Anglia) based in Wisbech has invested heavily in the Simon Moos AVC dewatering equipment. ADC were contacted by Ian Watts the technical engineer/team leader for Black Sluice Internal Drainage Board (BSIDB) to de-sludge a 250m meter section of Fenland Syke on the outskirts of Boston Lincolnshire. This section had limited access and was unable to be cleaned by conventional means. BSIDB is responsible for 34 pumping stations and the maintenance of 500 miles of watercourses within the area.
A technical solution to the problem
Mike Reeve and Steve Paige the directors of ADC then contacted Steve Lawie the UK & Ireland sale manager for Simon Moos to come up with a solution to the problem, a problem Simon Moos has tackled many times beforein his native Denmark.
Two Jet-vacs remove the wet sludge
Both ends of the Dyke section were dammed and the water over pumped to reveal the sludge and debris below. Two conventional jet-vacs were used to remove the wet sludge and a team of men were placed in the dyke to work the suction hose.
Separating the solid and water with polymer and dosing unit
Once a jet-vac was filled, the sludge was transferred via the Moos polymer make up and dosing unit which causes the separation between the solid and water fractions on-route to the Moos roll-on-off AVC de-watering container where the de-watered solids form a dry cake
Dry caked silt is transported for disposal
The water fraction or permeate is then allowed to return to the water course behind the gang working the wet sludge to the jet vacs. Once the de-watering process has finished the cake is then transported for disposal and the process is repeated.
The directors at ADC (East Anglia) are constantly looking for ways to improve the companies service to their customers.
Efficient system in polymer induced dewatering
Mike Reeve (Operations Director) : ‘We are commited in the search for new technology and innovations. These searches have led us to many different places throughout Europe. Our latest addition comes from Denmark in the form of mobile silt/sludge dewatering units manufactured by Simon Moos Maskinfabrik A/S, a company who has been workingin the effluent/sludge dewatering sector for many years and has developed efficient systems in polymer induced dewatering, Steve Lawie from Simon Moos’s worked closely with us getting this project started by sharing his expertise with us’.
Massive reduction in landfill
‘This is the solution to the difficulties of efficient wet waste disposal that we now encounter due to far fewer facilities being available to us which will accept tanker waster into landfill. We can now offer our clients a better environmental alternative. By de-watering river, culvert silt/sludge’s by this method we are able to reduce the amount of waste removed by between 75% to 95% depending on the material that we are treating. This not only brings a cost saving to our clients but also vastly improves any environmental impact with massive reductions in material going to landfill’.
