The dredging and screening of sewage matters (MDV) require a simple, robust screening system with few consumables, in order to recover the maximum number of wipes in particular: this is the role of the modelPACK MDV.
The MDV Pack SERCOURB / SERCOMP is used for screening waste matter and liquid grease.
The dredging and screening of sewage matters (MDV) require a simple, robust screening system with few consumables, in order to recover the maximum number of wipes in particular: this is the role of the model PACK MDV.
A curved screen SERCOURB inserted in a stainless steel box above ground entirely covered, is used for sieving. Its curved grid retains particles larger than the mesh size, recommended at 10 mm. These are scraped and pushed to an integrated screw compactor SERCOMP.
The PACK MDV is made up of the following elements:
A curved screen SERCOURB, inserted in an above-ground box, having the following characteristics:
A sieve screen, curved, removable, made of stainless steel plates laser cut with a 10mm mesh. (Different mesh available on request)
Two grid widths are available depending on the discharge flow rates:
The scraping system includes:
In standard, to protect the bar screen, a stone trap is integrated directly into the vessel. The filtrate evacuation is made via a tap fitted with a valve, and the pebbles are extracted manually directly into a trash can.
Alternatively, the pebble trap can be installed upstream of the stainless steel box. Its bolted lid is equipped with a siphoid blade that breaks the flow and directs the stones to the bottom of the structure where a basket made of perforated sheet metal is laid.
It is recommended to handle this basket with a hoist or other lifting tool, as its full weight can be important.
The pebble trap is equipped with a drain stitch on its bottom.
