Mechanical and Manual Bar Screen is a wastewater treatment screening device designed to remove large solids, debris, and floating materials from water or sewage before it enters further treatment stages. It is typically installed at the inlet of treatment plants, pumping stations, or industrial effluent channels to protect downstream equipment such as pumps and clarifiers.

Key Features:

• Types:

  • Manual Bar Screen – Operated by hand using rakes or hooks, ideal for small-scale or low-flow installations.

  • Mechanical Bar Screen – Equipped with automated rake mechanisms, chains, or brushes for continuous cleaning without manual intervention.

• Material of Construction: Mild Steel with anti-corrosion coating, Stainless Steel (SS304/SS316) for durability and chemical resistance.

• Bar Spacing: Customizable (commonly 10–50 mm) based on debris size requirements.

• Mounting: Channel-mounted or self-standing designs available.

• Operation: Inclined bar arrangement for easy debris collection and disposal.

Applications:

• Municipal wastewater treatment plants

• Industrial effluent treatment systems

• Irrigation canal intake structures

• Stormwater pumping stations
