Sereco - Model FC - Screw Sludge Filter
From Fine Screening
The screw filter is suitable for many applications, in particular for the micro-screening and for the filtrations of sludge and floating materials of civil or industrial wastewater treatment plants. The type FC consists of one multifunction screw and a semi-cylindrical filtering screen, which is, in its turn, formed by longitudinal wedge wire bars. The screw is controlled by a sturdy gear motor ensuring the filtering screen cleaning, the lifting, compacting and sacking of the screened material.
Products Details
That effect is achieved by the contemporaneous decreasing of the diameter and pitch of screw turns and by the special cylinder with friction-draining function. The screened material, before being discharged and sacked in a suitable container, is submitted to compaction and de-watering involving an about 50% decrease in weight. The screw filter is able to totally eliminate the suspended solids having diameter bigger than the size of the filtering gap, and considerably cut down the polluting load. Moreover, the completely closed body, which is a peculiarity of this equipment, avoids the diffusion of bad smells. On request, the screw filter can be provided with a system for the screened material washing with nozzles and pressurized water. The screw filter length and diameter are set according to the channel height and width; they therefore depend on the water flow to be treated. On request it is possible to have models with the length of the filtering screen different from the standard one, in order to increase the flow of water to be treated. Moreover, always on request, it is possible to have screw filters with the desired discharge height. The standard construction is in stainless steel.
