Screentec is an automatic vertical bar screen for Headworks, Pump Stations, Lift Stations, Wet Wells and Manholes. It protects pumps from rags, wipes, plastics and other solids. Screentec prevents pumps from clogging up, extends their life cycle, and improves the quality of wastewater treatment. Thanks to its vertical bar screen design, Screentec fits into narrow and deep structures, avoiding costly structural changes. Screentec does not have any moving parts under grade level, providing easy and safe maintenance for the operational staff.

Operating Mode

• A rake, set up on a sturdy belt, moves downward following two guide rails on each side of the frame.
• The rake collects all the material trapped by the bar screen.
• The rake travels upward, lifting up all the collected material.
• Collected material can be ejected into a washer/compactor, such as Compactec, or directly into a dumpster

Features & Benefits 

• Vertical Design: With a 90° installation angle, Screentec can fit any wastewater structure, up to 50′ deep.
• Minimal & Easy Maintenance: Screentec does not have moving parts at the bottom of the frame. Weekly maintenance consists only of a visual check of the top section of the frame. Grate-level access via the secure hood minimizes operator time, risk, and expense.
• Odor Control: The frame of the vertical bar screen is completely enclosed. Adding a washer-compactor with a bagger system, such as Compactec, maintains total odor control. Screentec can be installed in residential areas without risk of odor complaint.

Aqualitec Raketec 

Raketec is a multiple-rake bar screen system with no moving parts under grade level. It is a two-chain, free sprocket mechanism guarantying reliability and ease of use. A combination of stainless-steel rakes, and durable brushes thoroughly cleans debris from the screen.

Operating Mode

Two heavy-duty chains, driven by a powerful drive shaft, carry a system of rakes placed one foot apart.
Each rake contains multiple teeth and/or brushes, and the stainless-steel drive chains are connected with links bearings free to minimize maintenance. The chain rollers and chain guides are made of high-density polyethylene (HDPE), with no metallic lower bearings and no lower sprockets.

A scraper, placed at the point of discharge, cleans the screened material from the rakes and ejects the debris. Raketec’s rakes are designed to mesh perfectly with the bar screen system. The rakes clean debris from the bar screen, and convey waste material up to grade level.
Raketec can be set to run continuously, on a timer program (cycle on/off), or with a water level sensor.

Features & Benefits

• Simple Design: The gear motor, mounted at the top of the frame, rotates the drive shaft. The links of the chain fit into two cogwheels, located on each extremity of the drive shaft. Driven by the rotation of the shaft, the links of the two stainless steel chains slide into the HDPE track. With the HDPE track system, there is no friction between the chain and the frame of the bar screen. There is no requirement to grease the chain.
• Free Sprocket, no lower maintenance: At the lower part of the bar screen, the chains slide over two HDPE stationary rollers. With no moving parts at the bottom of the machine, no maintenance or underwater operation is necessary.
• High Capture Rate: A combination of stainless-steel rake teeth and brushes attached to the drive chains, placed one foot apart from each other, allows for extremely efficient cleaning. The brushes capture all rags and wipes, while the stainless-steel teeth assemblies clean between the bars of the screen to remove smaller debris such as grit, sand, and fibers.
• Minimal & Easy Maintenance: With no moving parts at the bottom of the bar screen, no maintenance is required. The weekly maintenance consists only of a visual check of the chains and the discharge chute. The back of the bar screen has an easy and safe access hood. If needed, brushes and teeth rake can be replaced quickly and easily by unfastening three bolts.
