The ECOSEWER has been designed ro remove from return water channels large contaminants such as rags, plastic, pieces of wood, etc, without holding back the smaller, more noble elements that must be recyded by the paper mill water treatment plants. With the ECOSEWER, waste is removed at a height that allows it to be collected in removable containers. The device consists of a tubular body in A1S1 304L or 316L stainless steel, the length of which varies in accordance with system requirements. The lower part, which must be positioned inside the channel, is fitted with a perforated grille that allows the passage of water and small solid matter, but holds back the large contaminants. There is a carbon steel, shaftless rotating screw inside the tubular body which is driven by reduction gear situated at the upper end of the device. The movement of this screw carries the waste upwards, allowing the water to drain from it. In the lower part of the tip of the screw, special brushes clean the entire length of the perforated grille to prevent any risk of clogging. The ECOSEWER is constructed in six standard sizes. The choice of Model depends on the size of the channel and the flow of water to be cleaned.
