Screening plays a vital role at municipal or industrial wastewater treatment plants. Stones, wipes, rags, and other large debris in collection systems ultimately end up at wastewater treatment plants. This material clogs pumps, aeration systems, and other critical process equipment, resulting in high maintenance costs and inefficient operation.

Screening can also improve the overall performance of the treatment plant by reducing the load on downstream processes and helping to improve the quality of the treated wastewater, which can be an important factor in achieving discharge permits and meeting regulatory requirements.

SAVÉCO’s FSM Basket Screen is a coarse screen used in pumping stations and treatment plants to effectively capture and remove large solids, rags, and debris from municipal and industrial wastewater.

General Description

The screen basket sits below the influent pipe in the wet well to remove debris from the wastewater as the flow passes through the basket. The basket is raised and lowered on guide rails using an electric hoist and stainless steel cable. Curved guide rails above ground allow for easy dumping of the screenings into a dumpster. The screenings drop onto a chute that directs the screenings into the dumpster.

The screen is raised and lowered by the operator via a local control panel with push buttons.

As the basket rises from the wet well, water drains from the screenings. The operator completes the emptying of the basket with a rake. Limit switches are installed on the cable hoist to limit the travel of the basket screen.

The basket consists of a stainless steel box with steel bars and perforated plates on the sides of the basket. When the basket is raised, a screen is lowered over the inlet to screen the wastewater entering the wet well. Therefore, no debris gets into the wet well when emptying the basket.

The equipment includes all the necessary frames and accessories required for the trouble-free and safe operation of the basket screen.

Features

• High reliability and robust construction
• Screenings easily conveyed to the dumpster
• Stainless steel construction (304SS or 316SS)
• Cost-effective with outstanding performance
• Low maintenance costs
• Low horsepower motor for lifting basket
• Suitable for outdoor use and cold weather operation
• No spray wash required
• No manual hand crank to lift the basket

Control Panel

The control panel is located near the basket screen in a non-hazardous location. The panel includes the power and control circuitry to properly operate the equipment and ensure compliance with applicable regulatory and safety requirements. By having the control panel located near the basket screen, plant operators can easily access the controls and monitor the equipment’s performance. This allows for quick and efficient adjustments to be made to the operation of the screening equipment, which can help to ensure that the process runs smoothly and efficiently.
