Pretreatment Equipment / Screws

For transport, dosing and caking of different types of waste.

Worm screws.

They consist of an endless screw that rotates on its own axis, thus moving the materials towards the discharge.

  • Made of carbon steel and AISI 304 or AISI 316 stainless steel.
  • Adaptable to installation needs.
  • The installation does not require civil works or large spaces.
  • High durability, resistant to oxidation and corrosion.
  • No jams or obstructions.
  • High transport capacity.


The ranger of conveyor screws consists of five different models

TC – Compactor screws

It is a compact unit that performs various functions in the process of removing solids from urban and industrial wastewater treatment plants, minimizing its moisture content and volume.
Special application in the treatment of solids from screening and roughing processes, helping to achieve greater dryness in the output sludge.

TT – Conveyor screws

For the displacement of waste. It is installed horizontal or with inclinations of up to 25º.

DA – Sand classifier

It consists of a sandbox made of GRP or stainless steel and a hollow shaft screw that collects and transports the solids, reaching a removal percentage of 97% of sand.
High efficiency in WWTP of discharges with high sand content, for example in potato and beet processing.

TTC – Channel screen conveyor

Sieving, transporting and compacting heterogeneous solids in a single unit. Equipped with a perforated mesh as a sieve at the water inlet for greater filtration. Variable incline of up to 35º.
Ideal for urban wastewater, agricultural industries, and food industries.

PPC – Compact pretreatment plant

Compact wastewater pretreatment unit that integrates a TTC and a DA in a single unit, thus carrying out several processes: roughing, sand classifying and degreasing.
Very effective equipment for the pretreatment of wastewater.

TTM – Mixing screws conveyor

It has a high mixing capacity since it comes with a double internal mixing system.

*Toro Equipment offers the option of acquiring pre-assembled equipment, ideal for WWTP that does not require civil works or for specific needs.
