Challenge : Dewatering 250 meter fenland dyke with limited access - unable to be cleaned by con¬ventional means!

ADC were contacted by Technical Engineer Ian Watts from Black Sluice In¬ternal Drainage Board and asked to de-sludge a 250 meter section of fenland Dyke with limited access - which was unable to be cleaned by con¬ventional means. Michael Reeve and Steve Paige, the directors of ADC, contacted Simon Moos Maskinfabrik A/S to come up with a solution to the problem. Simon Moos Maskinfabrik A/S has tackled this and similar dewa¬tering challenges many times before and this specific interesting dewatering challenge - is the reason why ADC heavily invested in the AVC/DOD dewa-tering equipment from Simon Moos Maskinfabrik A/S.

Solution : Dewatering the Fenland dyke with the AVC/DOD on-site sludge dewatering system.

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. Once a jet-vac was filled the sludge was transferred via the DOD polymer make up and dosing unit which causes the separation be¬tween the solid and water fractions on-route to the AVC roll-on-off dewater¬ing container where the dewatered solids form a dry cake. The water frac¬tion or permeate is then allowed to return to the water course behind the gang working the wet sludge which is then re-used to assist the transit of the sludge to the jet-vacs. Once the dewatering process has finished the cake is then transported for disposal and the process is then repeated.

Product facts

• The AVC (dewatering container) and the DOD (polymer and dosing unit) is a system characterized by:
• Large volume reduction - typical > 90 %.
• High dry matter percentage in dewatered sludge - normally > 15 %.
• High COD and BOD5 reduction - up to 95%.
• A mobile system with large draining capacity.
• A well-tested system with 30 years development experience.
• A system where you due to vol¬ume reduction obtain an attractive total economy as a result of re¬duced wages, fuel and depositing costs.
