Zero residual wastage Along with the Drencher tank and a dosifier for phytosanitary products, the system forms a close circuit without any residual wastage. Suspension solids and organic matter are collected in a big-bag for subsequent handling by an authorized company. 100% recovery of residual wastage The system pumps the waste water with its respective sludge by a press filter which retains any contaminating matter thus allowing 100% of soluble fungicides such as Imazalil, guazatine and fosetyl Al to pass.

The filter press system not only allows for the retention of suspended solids, but it also presses them into a compact material that dries over time, thus preventing the accumulation of significant volumes and reducing the removal costs to a minimum. Microbiological control Although the press filter acts as a barrier for the majority of fungi spores, including Penicillium, when the pallets are processed, a disinfectant is added during the topping up process of the treatment solution which allows the control of pathogenes during the working day until the emptying of the residual waste water to the SRC system for recovery. Save money by minimizing the consumption of fungicides with more uniform treatments The initial filling of the drencher tank is performed with a recovered solution that already has the adequate concentration of fungicides without requiring the addition of further products (except for thiabendazole) thus obtaining a saving by avoiding residual wastage containing fungicides. Furthermore it allows solutions to be renewed on the same day (once a certain DECCO IBERICA Post Cosecha S.A.U. Políg. Ind.

The amount of residue generated depends of the dirtiness of the boxes on arrival, which could vary between 2 and 4 kg. of residue for every 1.000 lt. of solution.
