Ecomacchine S.p.A. products

The machine operation is controlled by a Pause-ON timer. If the water level upstream the mechanical bar screen should increase and exceed a pre-set threshold, a level measurer can start the machine, even during the pause phase. The machine stop and the beginning of the pause phase is possible only whether the cleaning rake has reached a pre-set position out of water and the material collected has been discharged.

The water to be treated is conveyed into the feed hopper where the sand and any other solid particles decantation process takes place. The screw lifts the solid materials from the hopper to the discharge outlet. After having been separated from water, the sand is washed with clean water by a spraying nozzle; the dirty water returns to the tank and the washed sand is lifted by the screw. At the first starting, before the grit is lifted and evacuated outside the machine, the solid materials must begin settling down to form a bed of grit. When a sufficiently thick bed of grit is formed, the equipment begins evacuating the solid material (grit).

The water coming out of the diffusion drum to the sedimentation zone must have a very low kinetic energy in order to guarantee a good separation and settling of the solids. Moreover, the bottom scrapers must have a continuous and logarythmic profile in order to successfully convey the sludge into the central well in less than a complete rotation of the shaft, 270° (¾).

The sizing of the API tanks is made according to the AP (American Petroleum Institute) standards. Tank width: 1.5-4 mt Tank length: 5-20 mt.

The sizing of the feeding zone is based on the following parametres: • influent flow rate • dimensions of the pipings The water flowing to the sedimentation zone must have a very low kinetic energy in order to guarantee a good separation and settling of the solids.

Tank diameter: 3-15 mt

Diameter: 15-45 m. Peripheral drive clariflocculator with slow mixers

Belt filter presses type “400” main characteristic is their low price thanks to the design optimization aimed to use simple and reliable components. Most of the sludge dewatering plants achieve the maximum satisfaction by using this type of machines. Belt filter presses type “400” are manufactured in different models in order to meet the sludge characteristics and quantity to be dewatered.
