The TR-TRD screens are innovative solutions for solid-liquid separation, particularly suitable for high flow rates, and effectively combine filtration and compacting processes. These screens are equipped with a rotating screen basket, available in perforated sheet or wedge wire options, which serves as a filter. This is followed by a transport screw leading to a compacting and dewatering section, optionally equipped with either a chute or a bagging system.

Screenings are transported by a shafted screw to the compacting and dewatering section, where they undergo significant volume and weight reduction, by up to 40%. Typically installed within a channel of appropriate width, these machines can also be placed inside a receiving tank.

There are two models, similar in operational principle but differing in design:

1. The first model features a rotary drum screen where the drum and the shafted screw are powered by the same shaft, directly connected to the gear reducer. This configuration is ideal for small to medium-sized rotary drum screens.
2. The second model, designed for larger sizes, incorporates a double drive system: one for the drum and a separate one for the spiral conveyor. This allows the drum to rotate at a slower speed than the spiral conveyor, optimizing performance for larger units. This design also potentially reduces the overall absorbed power and the weight of the unit.

Key Features of the TR-TRD screens:

• Screw: Made from robust stainless steel AISI 304 / 316.
• Structure: Constructed with stainless steel AISI 304 / 316 for durability.
• Length: Customizable to fit specific plant layout requirements.
• Trough Protection: Equipped with bolted stainless steel wearing bars.
• Screen Basket: Options include a perforated plate or wedge wire screen.
• Screen Basket Cleaning: Features bolted brushes and spray nozzles for efficient maintenance.

Optional additions include a control panel, available in either electromechanical or PLC configurations, to cater to different operational preferences.

Application Areas:

• Municipal wastewater treatment.
• Industrial wastewater management in various plants.
