Sieves

Filtring with Auto-cleaning

Automatic filtration system solid-liquid, with mechanical auto-cleaning. The tamper allows solids with a minimum loss of charge. All materials with a diameter bigger than 80mm are removed. The auto-cleaning system is incorporated with a pipe cleaner to eliminate materials laying at the discharge surface (patented system B.O.P.I.U 97016780). Flow-rate for tampering variable between 50 to 2125 m3/h.

Helical Screw

Combined equipment for the separation of solids present in waste waters, for it performs transport, compaction and dehydration. This equipment is composed by a charge funnel, transporting screw and compactor. The filtration area can be of Johnson profile between 0.25 and 2mm, or with perforated sheet between 3 and 10mm of drilling diameter. The flow-rate may vary between 25 and 1100 m3/h.

Vertical Helical Screw Sieve

Combined equipment for the separation of solids present in waste waters, for it performs transport, compaction and dehydration always in vertical working position. This equipment is composed by a filtration area with a charge funnel, transporting screw and a compactor. The filtration area can be of Johnson profile between 0.25 and 2mm, or with perforated sheet between 3 and 10mm of drilling diameter. The flow-rate may vary between 4 and 440 m3/h.

“Basket-like” Helical Screw

Combined equipment for the separation of solids present in waste waters, for it performs transport, compaction and dehydration. This equipment is composed by a basket shaped filtration area, transporting screw and compactor. The filtration area can be from 0.5 to 6mm. Flow-rate may go up to 4000 m3/h.
